Cutting corrugated sheets can be done using hand or power tools. During this procedure, it is important to follow some rules so as not to spoil the material and shorten its service life.

The corrugated sheet consists of a steel sheet that serves as a base, coated on both sides with an anti-corrosion protective layer, then a primer, a layer of protective paint with inside and polymer coating - on the outside.

Structure of corrugated sheet

Therefore, it is very important to cut such a multilayer structure carefully and with minimal damage. If you ignore the rules outer covering will be destroyed, and the unprotected steel will corrode.

Another nuance to remember when working: polymer coating It is not resistant to high temperatures - under their influence it burns out. Cutting and any other processing of corrugated sheets can only be done using a cold method.

What is the best way to cut corrugated sheets based on these features?

Hand tools

They can be used for small jobs or for operations that require high precision.

Metal hacksaw and jigsaw

The most commonly used tool for cutting corrugated sheets is a hacksaw.

Using it, you can quickly and accurately make a cut without leaving burrs or nicks along the edges. Cutting a sheet straight takes little time and is easy, but figure cutting You won't be able to use a hacksaw.

Regular jigsaw - good option, if you want to cut the sheet not along straight lines, but along broken lines. Both tools are used for sheets with a relief height of no more than 25 mm.

Scissors

Scissors for cutting metal are used only when it is necessary to cut the material in the transverse direction, for shaped cutting, cutting thin strips or for a small amount of work. Treat them large number steel sheets will not work, the work is slow, and the edges of the corrugated sheets at the cut points are bent and need to be leveled with a hammer or mallet.

Electrical tools

Will help you cope with a large amount of material.

Bulgarian

Manufacturers of the material do not recommend cutting corrugated sheets with a grinder for several reasons:

• The cut area is heated during the process, and the polymer coating melts;
• the material may be damaged (chips and cracks will appear on it);
• the edges are torn and require additional processing;
• the sparks produced by the tool during operation fall on distant areas of the sheet and damage the coating even there, thereby spoiling the corrugated sheet not only at the edges.

However, many ignore the manufacturers' warnings and use an angle grinder to cut corrugated sheets. If there is no other tool, then you should at least purchase a special disk for cutting corrugated sheets to reduce damage to the material during cutting. The disk is a thin product up to 1.6 mm thick with teeth made of carbide materials.

1. The tool must be positioned so that the disk rotates in the direction of movement of the tool, and not against it. This way, the teeth will grind less, and sparks will not fall on the worker’s hands.
2. It is necessary to place under the sheet wooden boards so that the corrugated sheet is suspended and does not come into contact with the ground or table. This is done in order to protect the workbench and tools from damage.
3. After cutting, the edges of the material must be coated with a primer or other protective equipment to protect steel from corrosion.

Jigsaw

You can use a jigsaw for work only if the tool is professional: household, for home use do not have sufficient power for such a task. In addition, it is almost impossible to choose a blade that is suitable for cutting thick steel sheets for home jigsaws.
A powerful jigsaw is suitable for creating a shaped or curved edge of corrugated sheeting.

Cutting corrugated sheets with a jigsaw

How to cut corrugated sheets correctly using this tool:

• you will need a special table with clamps for the sheet so that it does not vibrate during work, or an assistant;
• the corrugated sheet must be pressed firmly against the supporting surface so that strong rattling does not occur during operation;
• It is not advisable to use a tool to cut material whose wavelength exceeds 20 mm.

Electric scissors

Electric scissors for cutting corrugated sheets come in 2 types:

1. Slotted ones are best suited because they are equipped with a special head for an even cut and do not leave bends in the places where the material is cut. They can also be used for shape cutting.
2. Nibblers also do not leave bends, since they cut corrugated sheets along two parallel lines. They can also be used for shape cutting. After work, no nicks remain on the material.

Cordless shears for cutting corrugated sheets

Circular saw

Can I use a circular saw to cut corrugated sheets? Yes, but you should use a disk with fine carbide teeth. Additionally, to protect the polymer coating, a special device is installed: a slit is cut in the center of a board or plywood 1 m long and 30 cm wide.

Before work, place a board on the sheet, positioning it so that the gap runs exactly along the area of ​​the future cut - it will serve as a guide, and the disk will not scratch the material. You need to cut sheets with a saw, setting the operating speed to the minimum value.

Drill with special attachment

Drill attachments

A special attachment for an electric drill works on a principle similar to that used by nibblers to cut. It can also be used for cutting and fitting corrugated sheets in hard-to-reach places, but this will require experience in handling the tool.

Edge processing

Having learned how to cut corrugated sheets, it is worth learning how to protect the cut points from corrosion, since any of possible ways will damage the polymer coating.

Processing the cut edges of corrugated sheets

Open areas The bases of the sheet are most vulnerable to external influences, so to restore their protective properties they need to be treated with special compounds.

To do this, moisture-resistant and anti-corrosion agents are first applied to the cut areas, and then painted. Often the paint is supplied with the corrugated sheeting, but if it was not included in the kit, you should choose the appropriate color and structure yourself. A layer of paint increases the resistance of the material to adverse external factors and extends the service life of the product.

Corrugated sheeting is a sheet of galvanized steel with a profile and a polymer coating. By appearance is similar to corrugated sheet metal, but due to the polymer coating, the cutting methods of the material in question roofing material and the tins are not the same. In order to figure out how to cut corrugated sheets and which method to choose for this, you need to familiarize yourself with the pros and cons of tools designed for cutting the material.

• grinder (angle grinder);
• electric hacksaw;
• manual and electric jigsaw;
• electric scissors;
• hand circular saw.

Grinder or angle grinder (angle grinder)

Manufacturers of this roofing material do not recommend using a grinder for cutting it due to the thermal effect on the polymer coating. However, even some sellers of corrugated sheets use it as the most convenient cutting tool.

The durability of corrugated sheets depends on correct installation and selection of cutting tools

When using an angle grinder, certain rules must be observed:

1. To work with profile sheets, you need instead abrasive wheel use a disc with carbide teeth. Such discs are called discs for cutting corrugated sheets.
2. The thickness of the disc should be from 1 mm to 1.6 mm.
3. To avoid corrosion, the cut area is covered with quality paint corresponding color.

When using a special blade, the cutting edges are very thin and neat.

Worth paying attention:
Some craftsmen, using a disk with diamond coating, cut a whole pack (10 sheets each).

When using a special disk designed for cutting corrugated sheets, the edges of the cut are smooth and neat

Using an angle grinder has its advantages and disadvantages. The advantage of using this tool is the cutting speed and convenience. Its main disadvantage is thermal damage to the polymer and zinc coating, burning of the edges and burning of sheets by sparks flying from the angle grinder. In addition, hot metal particles adhering to the surface contribute to the formation of corrosion. Torn edges of sheets after cutting with a grinder require a lot of time to remove burrs. During operation, the tool creates a lot of noise. The use of a special disc designed for cutting corrugated sheets eliminates many of the negative aspects of using an angle grinder.

Pros and cons of hacksaws for metal

When using this tool, the coating of the profile sheet is subject to the least destruction. Corrugated sheeting does not offer much resistance when cutting, so even handmade will not take much effort and time, and the absence of thermal effects helps preserve the coating of the material.

Advantages of cutting corrugated sheets with a hacksaw:

• speed;
• accuracy;
• no significant effort required.

Disadvantages of cutting sheets with a hacksaw:

• when working with a hacksaw, straight cuts are easily made, but cutting out curved shapes is impossible;
• When using a hacksaw for metal, you will need a special cutting table.

A hacksaw is used to make straight cuts

Jigsaw manual and electric

A jigsaw is a tool that, unlike a hacksaw, allows for curved cutting of corrugated sheets. There is no significant difference between a conventional and electric tool, but with the help of a jigsaw the work gets done faster.

Manual and electric jigsaws are used for cutting short-length corrugated sheets famous brands, the corrugation height of which is not more than 25 mm. Sheets can be cut lengthwise and crosswise, but the sheet must be pressed so that it does not vibrate. Cutting corrugated sheets is carried out at high speeds using the finest-toothed metal saw.

This is important to know:
To increase the cutting speed, it is not enough just the reciprocating mode; it is necessary that the tilt of the file be longitudinal.

When cutting electric jigsaw the edges burn, but not as much as when using an angle grinder

Disadvantages of using a jigsaw:

• the tool is not very convenient for cross-cutting sheets with a profile height of more than 25 mm;
• not convenient for cutting thin strips;
• the cutting speed is inferior to the grinder;
• when working with an electric jigsaw, the edges burn, but not as much as when using an angle grinder;
• unpleasant noise.

Features of using metal scissors

Advantages of cutting profile sheets with metal scissors:

• This is an indispensable tool for cutting thin strips.
• Provided they are sharpened well, they cope well with cutting across the wave.

Disadvantages of using the tool:

• Metal shears do not cut corrugated sheets lengthwise well, since the sheets have little flexibility in this direction.
• The main disadvantage of cutting with such scissors is the not very smooth edges of the cut.

Great tool for cutting thin strips

Electric scissors: effective and convenient

Electric scissors are quite convenient to use

Hand circular saw

Sheets of corrugated sheets can also be cut well with a hand-held circular saw, on which a fine-toothed disk with pobedit teeth is installed. For convenience and quick work using a circular saw, you will need an assistant. The cutting feed should be minimal.

To avoid scratching the paint on the profiled sheets, a conductor is made from a strip of plywood about 1.5 m long and 300 mm wide. A groove is cut in its center along the entire strip, not reaching the ends, which will serve as a guide for cutting. Two points are marked on the sheet along the cut line, and a jig is placed on them. The groove should coincide with the marked points. After this, the sheet is pressed well and cutting is performed.

A circular saw with pobedit teeth is an excellent tool for cutting corrugated sheets

This is important to know:
Cutting profiled flooring, which, unlike steel sheet, has a profile and an anti-corrosion coating, requires taking into account these characteristics of the material. Due to the sensitivity of the coating to high temperatures, cold cutting methods are preferred. These conditions and limitations must be taken into account when selecting a tool. For example, the use of plasma cutting, welding, autogen and other similar tools does not meet the requirements for cutting corrugated sheets, as it is associated with exposure high temperature. It is also not recommended to use abrasive tools that tear off and char protective coating.

Profiled flooring – aesthetic and durable material, which justifies its purpose provided that it is installed correctly and the tool for cutting it is selected in accordance with the manufacturer’s requirements.

The popularity of the material is due not only to its low cost, but also to its ease of processing. In this article we will look at how to properly cut corrugated sheeting so as not to damage its protective zinc and polymer layer. For cutting you will need ordinary tools, many of which are likely to be found in any home. Since the corrugated sheet weighs little, it can be sawed right on the spot.

Features of the process and material

Rolled metal with stiffeners in the form of waves, squares or trapezoids is made of steel and aluminum with a thickness of 0.3-1.2 mm. Thick sheets marked “C” (wall) are used mainly for the construction of fences. Load-bearing corrugated sheeting “N” and roofing “PK” are more suitable for arranging canopies and roofs. The “NS” brand is universal and is used for covering the roofs of buildings and structures and erecting fences.

Despite the ease of processing, when cutting profiled sheets it is necessary to adhere to certain rules so as not to disturb the galvanized surface and special protective film. Otherwise, the material will quickly deteriorate and begin to rust.

What is the best way to cut corrugated sheets? Power tools:

It is definitely difficult to answer this question. Depending on specific task: material thickness, cut line shape and installation features are used different types tools. Much depends on personal preferences.

Bulgarian

Prolonged exposure to high temperatures causes the greatest harm to the galvanized surface of corrugated sheets. Polymer or paint coating. The use of gas-cutting equipment, as well as grinders with conventional discs, for processing corrugated sheets is extremely undesirable. Indeed, in the process of peeling and even burning of the coating, edge corrosion quickly appears - lateral cracks at the ends of the sheets.

Abrasive discs are capable of heating metal up to 600°C. For acrylic, polyurethane or PVC coatings, they are dangerous and fly out for quite a long time. long distance sparks from under the disk. Plus, after cutting with ordinary discs, burrs remain on the metal that will need to be removed. And the tool makes a lot of noise when cutting.

Cutting with a grinder is allowed only with the use of cutting discs with finer teeth. The edges after processing are quite smooth, with minimal damage to the coating. However, even in this case, in order to avoid the appearance of pockets of corrosion, you should be extremely careful and avoid overheating and sparking. By the way, noise when cutting cutting discs much less.

Disc for cutting corrugated sheets with a grinder

To work with profiled sheets, you need to purchase a special disk of small thickness (no more than 1.0-1.6 mm) made of carbide metal. It is intended specifically for cutting profiled sheets. The edge after processing is more accurate. Some specialists with diamond-coated discs can easily process a pack of corrugated sheets with a thickness of 10 sheets at once.

Jigsaw

If you don’t have other tools at hand, you can use a jigsaw to cut a small amount of material with a profile height of up to 20-25 mm. With a high wave it will tear the canvas. And the tool itself can quickly fail.

Before starting work, the sheet is fixed on the table (ordinary sawhorses are also suitable) so that the edge is suspended 10 centimeters from the surface. It is more convenient to use a jigsaw with a laser pointer - the line will be smoother. It is pressed tightly against the sheet and cut along a pre-designated line. To avoid injuries, you only need to hold the corrugated sheet, and not completely lean on it.

It is more difficult to cut a large amount of corrugated sheeting with a jigsaw, so professional roofers use it mainly to obtain shaped cuts. Such an adjustment may be necessary when laying the roof in areas adjacent to smoke or ventilation pipes. It will take much more time to obtain long longitudinal lines using it than when working with an angle grinder.

Important! Just as in the case of an angle grinder, the jigsaw should not be set at high speeds. Otherwise, the corrugated sheeting will simply burn out.

Electric shears for metal

Working with them when processing thin 1-mm metal is quite convenient - they are not inferior in speed to an angle grinder. With some skill, in a short time, electric scissors can cut a sufficient amount of material both in a straight line and along curved lines.

However, tin snips often curl the edges. Therefore, after processing, you may need to straighten the sheets with a mallet. If it is not at hand, the edge is trimmed with a regular hammer, after placing a wooden spacer.

Ideal option for cutting - nibblers. Essentially, this is a miniature punch press. Since the cut line goes in two directions at once, the corrugated sheet is not deformed. You can even start work from the middle of the sheet. To avoid burrs, before starting work, adjust the scissors so that the tool is turned at 90° to the line being cut. However, the tool is not cheap, and it is used mainly by professionals.

Electric circular saw

Speed hand saw 2 times less than that of an angle grinder, so the metal almost does not melt during processing. With this power tool you can cut quite a large amount of material in a short time.

An electric saw, just like a grinder, must be equipped with a disk for cutting corrugated sheets - they are sold in all construction stores. A special cutting table will also be needed. When working, you should act carefully - the saw produces a large amount of chips, which can fly off at any moment. If you have no experience working with it, it is better not to undertake cutting corrugated sheets.

Advice! To adjust the profile, you can use a drill attachment. It is quite capable of cutting small sizes of corrugated sheets in hard-to-reach areas.

Hand tools for corrugated sheets

In addition to power tools, there are also hand tools. Working with them is difficult and slow, but hand tools has its advantages. They may well be useful for small amounts of work or the need for a neat cut.

Hacksaw for metal

Professionals often use this tool for cutting profiled sheets. Of course, working with it is a little more time-consuming. But cutting with a hacksaw has many advantages:

• the cuts are perfectly smooth, without chips and do not require additional processing;
• it can cut even the thickest sheets without any problems;
• there is no need to lay a cable to the installation site - in this case there will be no need for electricity;
• a hacksaw is safer than any power tool, and a non-professional can work with it - the likelihood of injury is much less;

• Great physical strength is not required when working: it is quite possible to cut roofing sheets with your own hands.

To work, you will need a table and devices for fixing sheets. Otherwise, you will have to hire an assistant who will hold the corrugated sheet.

Important! Use a hacksaw to make straight cuts only. Curvilinear lines are best done with scissors.

Jigsaw

With this tool it is possible to make cuts of any shape, including curved ones. But manual jigsaw much smaller in size than a hacksaw, so it will take a long time to cut. Perhaps it can only be useful for processing short curved sections. As with the jigsaw, the limitation is the wavelength. With a profile over 25 cm, the edges will be cut unevenly and will look torn.

Metal scissors

This tool may be needed to obtain curved cuts. It can also be used for processing a small number of thin-walled corrugated sheets. However, in any case, the cutting process will be longer than when working with a power tool.

The only advantage of metal scissors is the complete preservation of the coating during processing. But it is better to use them as additional tool in the event that edge processing across the wave is required. The ideal option is slotted scissors. Punching and knife cutters do not have a special head that allows for an accurate cut.

How to protect cut edges from corrosion?

Even if special tools are used, the edge of the corrugated sheet after cutting requires additional processing to protect it from oxidation. To do this, you can cover the edges of the sheets special composition(mastic or primer) or paint the cut lines with anti-corrosion paint similar in shade to the color of the protective layer.

When selecting corrugated sheets special attention is given to its length - in order to avoid transverse joints, it must exceed the dimensions roof slope. Due to this, it is possible to improve the roofing protection against moisture penetration, as well as simplify the installation procedure. If it is exceeded, the material is adjusted - trimmed in accordance with the required parameters.

It is better to place short sheets of corrugated sheets horizontally in rows, starting from the bottom and up to the ridge. Regardless of the choice of direction (from right to left or vice versa), subsequent sheets are placed on top of the previous ones and attached to the sheathing.

Where sheets are joined along slopes, the overlap level should be at least 200 mm, and bitumen sealant should be applied over the joints.

Those who install the roofing material themselves must take into account that there must be a small gap (20-40 mm) between the corrugated sheeting and the thermal insulation layer for ventilation of the under-roofing pie. Next to the ridge and at the nearest 1.5 meters from it, the sheets should be fastened with double fasteners, that is, not only to the sheathing, but also to the purlins.

When repairing a roof of any structure, the sheets should be placed parallel to the eaves with an allowance of 40 mm, that is, the sheet should still hang slightly from it.

Adjacent nearby sheets are fastened with one self-tapping screw. When laying roofing, and also when adjusting the material to the required parameters, you need to be extremely careful so as not to damage protective layer sheets. If at the end installation work, large overhangs are noticeable, then the metal profile is cut to remove excess material.

How to properly attach corrugated sheets?

Material when laying on wooden sheathing fastened with self-tapping screws at the rate of 6-8 fasteners per 1 sq. m.

You should also adhere to some well-known rules:

It is not recommended to screw in screws “live”, so the hole is drilled with a drill with an increase in diameter by 0.5 mm from the size of the self-tapping screw. Fastening must be done strictly at right angles with the sheets tightly pressed to the sheathing. If some changes are necessary, you should decide in advance how to bend the corrugated sheet, because if at this stage the structure is displaced or the seal is skewed, then when attaching the self-tapping screw, a through hole will be formed.

For convenience, you can tighten the screws with a screwdriver or drill. The screws are made of a special material, so they are easily attached to metal sheathing.

It is forbidden to nail corrugated sheets, as they can easily come off during strong gusts of wind. If you need to shorten the length of the sheet, you can use a grinder with a special disk inserted into it for cutting corrugated sheets, and avoid gas cutting and welding of the material.

Features of fastening the material in hard-to-reach areas:

• Where corrugated sheeting is laid near vertical surfaces (pipes, walls), joint strips are installed.
• The structure of the ridge element must also be securely fastened using a sealant.
• When laying a coating up to 0.7 mm thick, in order to avoid accidental damage to the roof, you will need wooden scaffolding and special shoes, a cutter for metal profiles, which is offered on the market along with other components, would also be useful.
• At the final stage, the corrugated board is cleared of debris, shavings, scratches and cut points are painted.
• After 3-4 months, you should check the quality of fastening of the screws and, if necessary, tighten them.

Corrugated sheet cutting technology

The structure of corrugated sheet metal is similar to a tin sheet, but it has some peculiarities in installation techniques, in particular, this concerns questions about how to bend a metal profile and cut it correctly.

Since the material consists of a metal base and a special protective coating against corrosion, when cutting it, it is necessary to ensure the integrity of this layer.

When choosing a method for sawing a coating, its resistance only to low temperatures is taken into account, that is, you will need cold method cutting As a rule, these can be scissors for cutting corrugated sheets and other tools that will be convenient for the developer and will be able to meet the requirements.

Naturally, cutting with plasma, autogen and other similar tools is not suitable due to the high operating temperature. The same applies to abrasive methods, which destroy and char the material in the cuts.

So, what is optimal for cutting corrugated sheets:

1. A hacksaw for metal is the most safe tool for working with corrugated sheets. Despite the fact that the entire procedure will be performed manually, it does not take much time, since the material can be easily cut, while the protective coating remains intact. The only disadvantages of this technology include the inconvenience of working with complex shapes, which requires a special table.
2. If you need to get more complex curved shapes, then you can’t find anything better than a jigsaw. The tool can be either electric or manual. A jigsaw not only simplifies the process, but also quickly cuts sheets required sizes, taking into account the original ones.
3. The building materials market offers manual and electric shears for corrugated sheets, which, although not in great demand among professional craftsmen, will do an excellent job when cutting metal sheets. Since everything depends on experience, beginners may be disappointed with this tool due to the formation of uneven edges of the material. You can correct the situation by covering such an edge with the next sheet.
4. An undeniable advantage Of all the listed methods of processing the material, cutting is done using a grinder, but not with an abrasive disc, as mentioned earlier, but with a special disc for corrugated sheets. It will also help in cases where you do not know how to make an arch from a metal profile or what tool to use.

The disc provides thin and delicate cutting, which is achieved through the use of a strong alloy for its production. Durable teeth do not break or bend even during prolonged work with metal.

As soon as the tool is selected, you can proceed to the description of the process of cutting corrugated sheets. It should be noted that even professional builders cannot maintain the integrity of the protective layer, which is why the service life of the material is significantly reduced.

The equipment described above only helps to reduce the destroyed area. The material cannot be restored, especially if bent corrugated sheeting is used, but to reduce the adverse effects, you can coat the cut area with an anti-corrosion and moisture-resistant compound.

How to cut corrugated sheets with a grinder, watch the video:

After cutting and processing the roofing sheet is completed, it is painted with factory paint, which is usually included with the material. If none was found, then you can purchase paint in a can in accordance with the texture of the roofing. This method of protecting seams from negative factors is even simpler and more convenient than traditional staining.

By following the basic rules for working with corrugated sheets, including laying and fastening, as well as cutting and processing sheets, you can achieve good result in the form of a high-quality and reliable roof covering (read: " ").

In the process of constructing private country house construction, metal roofing systems are used.

This is corrugated sheeting and metal tiles.

Almost eternal roofs. Lightweight, aesthetic, comfortable. But there is only one problem. When adjusting the junctions, it is necessary to cut off.

Below we will discuss which tools are best to do this.

Nuances when cutting corrugated sheets

There are difficulties in cutting metal profiles. Depends on the shape of the leaf. The surface is wavy and the use of traditional metal scissors is not suitable:

• The sheet will straighten in the cutting area. That is, the product is deformed, which will create difficulties during adjoining.
• Cutting corrugated sheets traditional way- not a productive process. When covering a large roof area, you will need a lot additional workers, which is economically unjustified.
• Cutting metal with regular tin snips will create difficulties when creating round, semi-circular geometric configurations.

The traditional use of cutting corrugated sheets is ineffective. There is a high probability of the scissors slipping during operation and damaging the painted layer. The consequence will be corrosion and premature exit of the roof from service.

Using various tools. Their pros and cons

The industry for the production of metal cutting tools is developing. Offers as cutting products:

• jigsaws;
• effective hacksaws;
• low-speed metal saws;
• electrified scissors;
• grinders and other products.

Tools for cutting corrugated sheets

The tools presented in the text are actively used in practice, although they have obvious disadvantages. Let's talk about the positive aspects first.

Pros

The point is that the tools can be used to adjust the profiled sheet. The cut is professional and satisfying technological requirements. The process of cutting corrugated sheets is active, productive, and convenient, although in some cases it requires additional processing.

Cons

They are created by the geography of the leaf surface. It is permanently convex. Has a corrugated appearance. System bends are also stiffening ribs. Not subjecting them to deformation is the main task of the carver. It is strictly prohibited to cut the sheet with gas cutters, since it is coated with an anti-corrosion compound that can be easily damaged. In short, it is advisable to cut corrugated sheets using the cold method.

Cutting corrugated sheets with a grinder

The grinder is a universal construction tool.

With an abrasive disc attached to it, it is easy to cut metal pipes, channels, other products. It cuts corrugated sheets perfectly, but heats it to a temperature at which it loses its anti-corrosion coating.

In order not to weaken the corrugated sheets before corrosive chemical reactions, after pruning they carry out additional processing slices. They are modified with “cold” tools:

• saws;
• jigsaws and so on.

To cut profiled sheets with a grinder, use the thinnest cutting disc that is produced by industry.

Working with thin cutting discs, a small part of the profiled sheet is heated. It is advisable to cut this area to a length of 3 millimeters. The cut end of the sheet is coated with a special varnish, which the selling organization offers to buy, along with corrugated sheeting.

An anti-corrosion compound identical to the factory sample is used.

Guarantees the integrity of the material in any climatic region of the country.

A very progressive method that involves cutting the corrugated sheet not to rafter system, but on the ground.

Undesirable

If you trim directly on the roof, the hot abrasive particles will damage the water barrier and disrupt the thermal insulation.

How to cut corrugated sheets with a jigsaw?

It's easy to do. Take a jigsaw, set the sheet vertically and begin processing the corrugated sheet.

The process generates a lot of noise, but it is mixed using special headphones. The worker receives an exceptionally thin cut. The jigsaw does not create large chips that could damage the protective layer of the sheet.

The versatility of the jigsaw is high. With its help, you can safely process a sheet with a ridge up to 2.5 cm high.

To operate the mechanism, a household power supply of 220 V is sufficient.

Advantages

They are obvious in the rapid cutting of the sheet and the negligible heating of the corrugated sheet in the saw area.

One hundred percent guarantee of safety when working with power tools. The electric motor is double insulated.

You can use a jigsaw on sheet metal without grounding the power tool.

High cutting speed ensures a clean cut.

The work of a jigsaw is based on the forward-reciprocating movement of the working element. The higher the speed of its advance, the less heating of the metal, the cleaner the cut.

Fundamental positive feature A jigsaw is that it is easy for them to cut complex compositional shapes from metal. This is facilitated by the adjustable angle of the jigsaw to the sheet.

Cutting corrugated sheets with a hacksaw

If the amount of work is small, then you can cut and make small sections with a hacksaw. But when covering a large object with corrugated sheeting, this method is extremely ineffective.

One can guess how much physical effort must be expended in order to complete the operation efficiently.

Second, a high-quality cut can be made in a straight line. Cutting an oval or an ellipse is unlikely to work. Geometric lines will be inaccurate and jagged edges will appear. All this will require additional processing.

Third, cutting metal requires a special table, which cannot be located in areas where the roof is installed. Many people don't consider this a big problem, but it still exists. Consumables you need a lot because metal blades are expensive. An economic question arises - is it worth using this tool at all?

Worth it because it's extremely safe method sections of corrugated sheets, prompt replacement of worn sheets with a new analogue.

Cutting a profile sheet with metal scissors

The profiled sheet is thin and can be cut lengthwise with special scissors. Using them for end cutting is somewhat problematic, since the corrugated surface of the corrugated sheet will be crushed by the force of the cutting parts of the tool. Such a sheet will not fit into the technological logic of the roof and will be disposed of. Cutting sheets vertically is a pleasure. The scissors work efficiently, like a well-adjusted sewing machine.

It is better to use metal scissors to refine the cut. Sometimes when trimming with other tools, it is necessary to smooth out errors. In this case, metal scissors are an excellent corrective tool.

Metal scissors are:

• manual die-cutting;
• with electric drive;

Manual nibblers are universal tool, capable of cutting at two levels, which allows you to cut a profile with a wave height of up to 2 cm.

Other tools for profile sheet cutting

Today, other tools are used for cutting corrugated sheets.

The list of such products should include attachments for an angle grinder.

Complete with it, the grinder is a productive die-cutting machine capable of working in different positions. She doesn’t care whether she cuts flat metal or with a complex relief pattern, which is inherent in profile sheet. The qualifications of the employee are important.

The spatial position of the grinder must be constantly changed. The cutting part of the nozzle must be in a perpendicular position to the material being cut.

A longitudinal electric saw with a special disk quickly cuts the metal profile, leaving behind an even cut.

The “Cricket” attachment for a drill is a know-how in the processing of sheet metal.

The tool is safe to use. Productive nozzle.
