How to cut a profiled sheet at home

  • Stationery knife. A good model will help you cut large sheets of polycarbonate very efficiently, but this will take a lot of time. It will be possible to complete the work quickly and efficiently only if the thickness of the material allows it to be done. So, polycarbonate with a thickness of about 4-6 mm is possible even for beginners. If it has a thickness of about 8 mm, only a person with sufficient experience in construction can work with it.
  • Jigsaw. Suitable for performing complex work, for example, giving polycarbonate a beautiful decorative shape, rounding, etc. You can cut it correctly with a jigsaw using a fine-toothed nozzle.
  • angle grinder. It is a simple and reliable tool. Even a small and inexpensive model will help you quickly and efficiently carry out the cutting process. The only thing you need to properly cut polycarbonate is experience with an angle grinder. If you do not have enough experience with such a tool, it is better to pre-practice with a piece of plastic.
  • Laser cutting. Perhaps one of the best tools for working with polymer materials due to its positive features: fast cutting speed, the highest quality and sharpest cut, extremely low probability of defects, ease of cutting the material.
  • Saws. Any circular saw will work for polycarbonate. When working with a saw, it is important to remember some of the subtleties and observe them: the teeth should be small and wide, the material is better fixed on the workbench, it is better to remove the protective polycarbonate coating after the end of the material cutting process.
  • Milling processing. Such equipment is suitable exclusively for monolithic polycarbonate. With its help, the working speed becomes very high, and the cut can be easily performed at any angle.

Attention! When using a jigsaw, it is necessary to work with several sheets of polycarbonate at once. Be sure to put a cardboard base under the material: it will prevent the possibility of cracking.


Beginners are usually interested in: is it possible to cut and how to cut cellular polycarbonate with a hacksaw or a hand saw? In the event that there is no experience, it is advisable not to use these tools: the blades along the cuts can crack. It is best to work with power tools. But both beginners and experienced specialists need to fix polycarbonate sheets well in order to prevent vibration and stress in the material, which is also fraught with bad consequences.

How polycarbonate is cut

So, the first tool is an angle grinder. Yes, yes, this is not a typo. It is the angle grinder, under the 125th circle for metal, that I use in order to make even cuts. That is, in order to make any even cut, I recommend using a small angle grinder. Even the cheapest will do. It withstands the load on sawing sheets with interest.

The only thing that is required is a little skill in working with this tool, since it is a highly revolving tool and if you use it inexperienced, you can ruin the sheet. It is advisable to pre-train on some polycarbonate waste. You can find waste from any master who is engaged in the installation of polycarbonate.

You ask, what else can you cut polycarbonate??

The second tool is a jigsaw. The most common household jigsaw. The file on it should be with fine teeth so that the carbonate is cut and not torn. This tool is easy to use and does not require any special training skills. But still, for greater confidence, you can also pre-train.

It is very convenient to use a jigsaw to cut fillets or cut complex decorative shapes. For even cuts, I do not recommend using a jigsaw as it takes more time for a cut than for a similar cut with an angle grinder.

And the third tool that I often use is a stationery knife, preferably of good quality. With him, I think any beginner in this business can handle. The main thing is not to rush when working with a knife, since the blades of this tool are very sharp and you can easily get injured.

With a stationery knife, you can easily cut honeycomb polycarbonates 4-6 mm, slightly more difficult polycarbonate 8 mm. I would not recommend cutting with a knife for thicker polymers, there is a high probability that the panels can be damaged. In general, I use a knife in cases where it is necessary to cut a small section of the sheet, so to speak, adjust it to size.

Of course, some craftsmen also use a file and scissors. Personally, I have never used these tools. I will say this, in principle, you can use this improvised inventory for cutting polycarbonate, so long as it does not violate the structure of polycarbonate and does not affect the correctness of the technology of its installation.

Well, here’s how to cut polycarbonate, I think we figured it out, let’s now look at how to properly cut polycarbonate.

Electric jigsaw

A household, most ordinary electric jigsaw is also quite suitable for working with polycarbonate sheets, only you need to install a file with fine teeth on it, otherwise the material will tear, not cut. This tool, like the angle grinder, is quite easy to use, but to be completely confident in the quality of the work, it is advisable to also practice in advance. An electric jigsaw is very much in demand, especially when you have to cut monolithic polycarbonate of complex decorative shapes or make roundings.

Note: If you have to cut thin sheets, experts recommend folding canvases of 10-12 pieces, and placing a layer of cardboard under them and then cutting everything at the same time.

When it is necessary to cut only one sheet, the risk of cracking increases significantly. To prevent damage to the material, you need to work only with a very well sharpened tool. There are craftsmen who use scissors when working with polycarbonate. This is also perfectly acceptable. The main thing is that the tool used does not violate the structure of the canvases.

The need for proper cutting of polycarbonate

In the course of any work, it is almost always necessary to cut polycarbonate in order to fit it to the size of the structure. It is advisable to perform this procedure correctly the first time. this will save you time and effort in the first place.

In case of improper cutting, the material may be damaged, deformed, which will make it impossible for its further use. And since polycarbonate cannot be called cheap, the costs are very tangible.

How to cut corrugated board at home

Decking is a building material used for arranging roofs, facades, fences, etc. Its main advantage is its simple processing. Since the profiled sheet is lightweight and lightweight, fitting is carried out directly on site. To cut a profiled sheet, it is enough to choose a simple hand tool and know the features of the technology.

The nuances of cutting profiled flooring

The professional sheet must be cut carefully so as not to damage the polymer coating

There are certain features in profile processing, which depend on the shape of the sheet. For example, if the surface has wavy mowing lines, you cannot use traditional profiled sheet cutting tools. These include scissors for metal, which contribute to the deformation of the panels and make it difficult to adjoin.

The use of classical equipment is irrelevant, since when laying roofing material on a large roof, it is necessary to involve 3-4 installers, which will not be economically justified. Scissors also make it difficult to create geometric shapes. In the process, there is a risk of damaging the painted layer. In the future, this will cause the development of corrosion and the need for premature replacement of corrugated sheets.

It is not recommended to cut the profiled sheet with an angle grinder, since in this case the coverage will be automatically canceled.

Tool options for cutting corrugated board

The production of cutting equipment is developing, offering various innovative technologies for metal processing. However, most installers use traditional tools:

  • jigsaw;
  • hacksaw;
  • saw;
  • electric shears.

The advantage of this equipment is the ability to use them for fitting profiled sheets. As a result of processing, the cut is correct and meets technological standards. Working with this equipment differs in productivity, but in a number of situations, anti-corrosion treatment of the edge is required.

The disadvantages include the task of the installer not to subject the surface of the sheet to deformation, since it has a corrugated convex appearance with stiffening ribs. It is not allowed to cut the material with gas equipment, since the protective coating may be damaged. Profiled flooring must be processed only “cold”.

Manual scissors are used for a small amount of work

It is recommended to use the following tools for cutting corrugated board:

  • The cricket drill bit is suitable for cross-cutting and shape cutting of material, as well as for working in hard-to-reach areas. In this case, the thickness of the metal should not exceed 0.8 mm.
  • Nibblers assumes longitudinal cutting, obtaining straight and curly lines, processing the sheet at the ends of the structure. The equipment belongs to the category of tools with high maneuverability.
  • Slotted shears are used for longitudinal and transverse processing of profiled sheets up to 2 mm thick. Additionally, the tool is used to create complex hole shapes.

Profiled decking is thin laminated metal that can be damaged if not cut correctly. The material has a protective polymer layer on top, therefore, the use of traditional equipment, such as a circular saw, a punching chisel or a clerical knife, is not allowed.

Cutting corrugated board with an angle grinder

Since an angle grinder with an abrasive wheel, as already mentioned, is not suitable for a profiled sheet due to severe damage to the coating, this tool can only be used in a set with special discs for cutting corrugated board, which are thin cutting wheels 1-1.6 mm thick with teeth made of tungsten carbide materials.

To avoid corrosion, after cutting the profiled sheet with an angle grinder, it is necessary to immediately process the edges with special paints.

The advantages of cutting corrugated board with an angle grinder are the speed of performing all operations and the relative ease of cutting the corrugated sheet.

The disadvantages of cutting corrugated board with an angle grinder are torn edges and a strong, very unpleasant soundtrack. Even if you use a special disc for cutting corrugated board, an angle grinder, in any case, is an abrasive tool, because the incandescent metal particles formed during the cutting process fall on the polymer coating and burn it, creating prerequisites for the appearance of foci of corrosion.

In addition, the torn edges of the profiled sheet after cutting require additional work to remove burrs. All this makes the angle grinder far from the best tool for cutting corrugated board.

Cutting profiled sheet with a hacksaw for metal

A fairly economical, convenient and popular way of processing corrugated board is a hacksaw for metal.

The advantages of cutting corrugated board with a hacksaw are accurate and fast cutting, no chipping and burrs, the ability to work independently without much physical effort. Usually, builders use a hacksaw to work with fences, gates, small roofs and other structures that require a small thickness of corrugated board.

The disadvantages of cutting corrugated board with a hacksaw for metal are the impossibility of making curved cuts and the need for a special cutting table to fix the material. Thus, in the case of complex cutting work, in addition to a hacksaw, you should provide for the use of another tool. However, all the disadvantages of a hacksaw for metal are successfully covered by the advantages of this method.

Cutting corrugated board with an electric jigsaw

The jigsaw is used for corrugated board, the height of the corrugation of which starts from 25 mm and is combined with a short length. Cutting with an electric jigsaw is carried out across or along the sheet, however, it is necessary to firmly press the profiled sheet so that it does not rattle.

Cutting should be done at high speeds using a fine-toothed saw specifically for metal. In the case of high speed, a reciprocating operation with a longitudinal inclination of the saw is recommended.

The advantages of cutting corrugated board with a jigsaw. low cost of work.

Disadvantages of cutting corrugated board with a jigsaw. inconvenience of transverse cutting of corrugated sheet with corrugation from 25 mm, practical impossibility of cutting thin strips, strong burning of the edges of the metal sheet and protective polymer coating, strong noise during operation.

Cutting corrugated board with scissors (conventional and electric)

Simple shears for corrugated board are used when it is necessary to carry out small works related to the installation of flooring, the construction of garages, gates and fences. Electric shears are used for wider Spectra tasks, however, when a straight edge of the cut does not matter.

How to cut corrugated board with scissors for metal, see the following

The advantages of both simple and electric shears for cutting corrugated board are fast, easy and high-quality cutting of thin and even strips, as well as cutting across the wave without damage.

Disadvantages of scissors for cutting corrugated sheets are uneven and rough edges of the cut. In addition, the low flexibility in the longitudinal direction makes it very difficult to cut the corrugated board along the.

What is the difficulty of cutting profiled sheet?

The profiled sheet is a rather thin product that is easily damaged during the cutting process. The second feature of the corrugated board is its coating with a layer of galvanized and polymer, due to which it becomes impossible to use conventional methods of cutting sheet metal sheets.

High-temperature methods of metal processing in this case are also not suitable, because the covering of the corrugated board, no matter how strong and resistant to unfavorable natural factors, it easily burns out under the influence of high temperatures. You can not cut the profiled sheet and abrasive wheels, as they severely spoil the coating, which leads to the formation of corrosion. So, what can and should be done to cut corrugated board?

Cutting corrugated board. how to cut the profiled sheet so as not to spoil the material

No one will argue that today corrugated board is an extremely popular (and often simply irreplaceable) material for construction and decoration. In this regard, for many novice builders, the question of how to cut corrugated board becomes very important, because, despite the acceptable cost of its sheets, damage to the covering of the profiled sheet can negate all the advantages of using this material and significantly slow down construction.

How to properly cut corrugated board, what tools are used for this and how to process the cut in order to avoid corrosion, is described in this article.

How to bend corrugated board?

In addition to cutting, the corrugated board can be bent, which allows you to significantly expand the possibilities of creating bent products for decorating wall corners, cornices and roof ridge.

To obtain a transversely bent profile, the corrugated board must be bent at right angles to the profile direction, and if a bending industrial unit is used for this when organizing mass production, then for a small-scale production process it will be enough to purchase a simple manual bending machine.

The most common design of this tool is considered to be a rotary one with a bending beam, and if you wish, you can complete this device with any additional functions that allow you not only to bend the corrugated board, but also, for example, to cut it.

Cutting corrugated board at home

In this article, we’ll cover:

  • what difficulties may arise in the process of cutting corrugated board,
  • what methods of cutting profiled sheets exist,
  • the advantages and disadvantages of these methods.

The main difficulties when cutting profiled sheets

Decking is inherently a thin material that can be damaged when cut. In addition, metal sheets are processed with galvanized and polymeric materials during production. In this regard, the use of classical metal cutting methods is not possible.

Another difficulty is associated with the fact that it is impossible to cut the corrugated board using high-temperature methods. This is also due to the characteristics of the metal coating, which starts to burn at high temperatures. And abrasive wheels lead to the formation of corrosion at the cut points due to severe damage to the protective layer. And the question naturally arises: how to cut the corrugated board and how to cut it in order to preserve the properties?

method of cutting profiled sheets

As mentioned earlier, the use of abrasive wheels is unacceptable, therefore, special discs must be used to cut corrugated board. These are special inserts up to 1.6 millimeters thick, the teeth of which are made of carbide materials. At the end of the cut, the edge should be treated with a special paint to prevent corrosion. This is a fairly fast, but not always safe for the protective layer method of cutting corrugated board.

profiled, sheet, home

This is one of the most economical and convenient ways to cut a profiled sheet. This ensures that the edges are neat and not jagged. In addition, it does not require much effort to complete the work. If a corrugated board of small thickness is used, then professional builders often use a hacksaw. Among the disadvantages of this method, it is worth noting the difficulty in carrying out a curved cut.

This option is suitable for small sheet lengths in combination with a corrugation height of 25 millimeters or more. It is important to firmly press the sheet so that it does not walk or rattle. Work is done at high speeds, and the file should be fine-toothed. With a low cost of work, there are some problems: thin cutting cannot be done in this way, and the edge of the metal burns badly, which leads to a violation of the protective layer.

For a small amount of work, special shears for corrugated board are suitable. They cope with both longitudinal and cross-cutting, and the process is easy and fast. Of course, not without drawbacks: the edge turns out to be rather rough and somewhat uneven.

These are 4 ways how to cut corrugated board at home simply and quickly, just choose the right one and get a tool for carrying out the work.

Electrified scissors

There are several types of scissors: slotted, cutting, sheet. But the best option would be slotted scissors. they do not bend the sheet, after work the canvas remains flat. You can even make a hole anywhere, start cutting the sheet. Burrs do not form on the edge, but for reliability it is still better to process the edges.

There is only one caveat to the instrument. the high price. If you work constantly with them, then the costs will pay off quickly.

Well, if you have to do one-time work, then such equipment is expensive.

Low speed metal saws

The hand-held circular saw works on the principle of an angle grinder. Among its disadvantages is an uneven edge. Rough edges are filed.

Tool overview

Profiled sheeting is a sheet material that has strong protection from several layers. It is based on steel up to 1.2 mm thick, coated with zinc, with polymer spraying. The profiled sheet differs in basic parameters. width, height, shape. The wall sheet is used for sheathing fences, walls. Roofing is required for roof sheathing. The universal sheet can be used for any type of work.

It is necessary to cut the corrugated board carefully, because its coating is sensitive to heat. Because of these features, it is better to perform processing only in a cold way.

Now on the construction market you can find a variety of tools for cutting metal. They can be roughly divided into 3 categories:

  • machine tool professional equipment;
  • electrical engineering;
  • hand tools.

Among other tools, the most popular are:

  • jigsaws;
  • saws for metal;
  • hacksaws;
  • angle grinder;
  • scissors.

The positive sides of such a variety are that the sheet can be neatly adjusted with all the ensuing technological requirements.

It is very convenient to cut a sheet with such devices.

After purchasing a roofing material, evaluating its parameters, as well as methods of operation, you need to decide for yourself the following nuances:

  • determine the quality of cutting in a certain type of work;
  • curly cutting or can be cut in a straight line with the mowing line;
  • if you need to cut off a couple of sheets, then there is no need to take an expensive device;
  • if, for example, processing of the product is not needed, then use an angle grinder;
  • important is the budget that everyone is willing to spend on equipment.

But using all the tools, it should be remembered that the sheet must be cut carefully, without disturbing its structure.

angle grinder

A grinder or angle grinder is also used for cutting profiled sheets. Although the use of the device has its drawbacks:

  • such an abrasive tool often damages the galvanized surface of the product. corrosion is inevitable;
  • sparks fly out from under the disk of an angle grinder during operation, which often cause damage to the sheet surface;
  • the finished product needs edge processing.

For use with an angle grinder, it is recommended to purchase a 1.6 mm thick disc with carbide teeth.

Basic cutting rules

To avoid problems in the cutting process, it is necessary to put a sheet with the same profile on the workpiece. Then take measurements correctly, make an incision first, and only then cut it off. At home, they use another method. also put the sheet on top, lean on it with effort, and then cut it off. When asked whether weight cutting is allowed, professionals give a negative answer. There is a risk of injury, ruining the profiled sheet, cutting off crookedly.

In order to carry out the pruning yourself, it is recommended to use some recommendations.

  • Always use protective equipment during the work process.
  • Hands with gloves will not get minor wounds and splinters.
  • Glasses perfectly protect eyes from metal particles.
  • Construction headphones are needed to protect yourself from noise.
  • Protect from other damage by a special suit.
  • Wear protective footwear.
  • If you have to work with an angle grinder. use a protective cover.
  • Observe all safety rules during operation.
  • When using electrical appliances, provide an emergency de-energization.
  • If you are cutting with an angle grinder, it is recommended to use a plywood jig. You can make it yourself at home. Conductor. protection of metal from tool sparks.
  • If a hacksaw is used for metal, then the above method is used when cutting.
  • The jigsaw is convenient to use when cutting a round hole. But measurements must be accurate. Such a tool is best used for cutting sheets of category “C” or no more than 21 millimeters.
  • Scissors are suitable for trimming roof material. over, electric shears will be able to work along and across the rib.
  • When cutting thin material, use the drill bit.

How and how to cut corrugated board?

When working with corrugated board, a specialist should know a lot about this material, especially. how and how to cut it. Ignorance of the question will lead to the fact that the material will be spoiled. How to cut metal sheets so that corrosion does not take them, this issue will be discussed in the article.



Professionals often use a drill bit to speed up their workflow. It is only worth remembering that when using the method, a person must have professional use skills, and it is better to choose a drill on a battery. It is optimal to use this type of work where a conventional tool cannot cope.

Manual scissors are necessary if you need to cut a small amount of metal.

They are used by amateurs to build garages, sheds, and other utility rooms.

Of course, for larger-scale work, it is better to use an electric shears. They cut the metal more accurately, it is convenient to cut the sheet across the waves, but with little difficulty.

Hand cut aluminum part

A relatively new tool is a renovator or a multifunctional mini-machine. He is able to cut sheet canvases up to one millimeter, starting from any point. It is fast and safe to operate, but noisy in operation.

Decking in factories is cut by laser or plasma cutting. Machine equipment allows you to work with large volumes. The laser can handle any holes with high precision without damage


A jigsaw can make curly cuts on a sheet: no other tool can boast of this. If small work is being done, then you can use a hand tool. For large volumes of work, an electric jigsaw is used. It’s a pretty nimble tool, but it has its drawbacks:

  • used only for a sheet with a wave of 25 millimeters;
  • longitudinal cuts with a jigsaw will have to be performed for a very long time;
  • the jigsaw works at high speeds, therefore, paint or primer treatment will be required at the cut points;
  • the polymer coating is sensitive to processing with tools, therefore, after all manipulations, it is necessary to process the edges additionally.
