Dimensions of metal roofing: length, thickness

Metal tiling today is the most popular roofing material for summer residents and owners of country houses. Its main advantages are low cost, long service life and attractive appearance. The dimensions of the metal roofing for the roof are standard, which makes it easy to calculate the amount of roofing required for the roofing of any configuration and the area of the sheets.

general description

Excellent performance characteristics of the metal tile due to its unusual structure. It is made of sheet steel 0.4-0.6 mm thick by the method of cold stamping. At the top, each sheet is first covered with a zinc layer, providing reliable protection against water, and consequently, from rusting the metal. Next, a passivation layer is applied, and then a primer layer. At the final stage, the sheets are coated with a special polymer composition, which has a color and texture. This layer not only protects the metal from adverse climatic and mechanical influences, but also gives the roof aesthetic appeal and expressiveness. Its name was not accidental. From a distance, the roofing sheets of this variety actually resemble expensive clay tiles.

Width

The dimensions of metal roofing for the roof in the marking are mandatory. The amount of material required for the skin is chosen, focusing primarily on the width of the sheets. Attention is paid not to general, but to useful. The latter is always less than the first, since metal roofing is laid on the lath of the roof with an overlap.

The total width of the metal sheet can be 1.16-1.19 m. The overlaps are usually 0.06-0.08 m in length. The useful width of the metal tile sheets is usually 1.1 m. However, sheets of 100 cm, 105, 118, etc. can be found.

Length

The size of metal roofing for this type of roofing can vary greatly. On sale there are sheets with a length of 80 to 800 cm. Therefore, if desired, you can easily pick up a material that is perfectly suitable for absolutely any roof. The length of the metal tile is always a multiple of 5.

When buying sheets for the roof should take into account the fact that the size of the overhang of the roof of metal should not exceed 40 mm. Otherwise, the metal may later bend or wrinkle. If the length of the skates exceeds 7.5 m, the metal tile should be laid in two rows. The angle of the ramp for this roofing material should not be less than 14 g.

Thickness of metal tile

So, what are the standard sizes of metal roofing for the roof, we have found out. Now let's see what the thickness of this material can be. As already mentioned, 0.4-0.6 mm steel can be used to make metal tiles. Also, the thickness of the material depends on the thickness of the polymer layer applied thereto. This figure is usually 25-50 microns. Thus, the thickness of sheets of metal can vary in fairly wide limits. The greatest demand for owners of country houses uses material at 0.5 or 0.45 mm.

Types of polymer coatings

The decorative protective layer of metal tile, therefore, can have a different thickness. The following types of polymer coating can be applied to the sheets:

• Pural. This polymer is considered an excellent protection against corrosion and can withstand temperatures from -15 to +200 g. Of all types of polymer coatings, this is the thickest - 50 μm.

• Polyester. For people with average incomes, this is the most suitable metal roofing (roofing). Price per sheet (the dimensions of this kind of material can be different), covered with such a layer, the lowest. However, it has a thickness smaller than the sheets coated with a pural - 25 μm. Metal tiles with such a protective layer can be mounted on roofs of houses built in regions with the usual climate without extreme temperatures. Today on sale you can find such sheets of a slightly different variety - coated with polyester in combination with Teflon. The polymer layer of this type is more resistant to various kinds of mechanical damage. The thickness of the Teflon-polyester coating is 35 μm.

• Polydrifluoride. This is the most expensive kind of polymer coating. Its advantages include, first of all, high resistance to burn-out. Therefore sheets with such protection are most suitable for the roofing of houses in southern hot regions. The advantage of polydifluoride is its resistance to mechanical damage and a very long service life. The thickness of the PVDF layer is 27 μm.

• Plastisol. Sheets of metal tiles with a coating of this type are rarely available on sale. The fact is that polyvinyl chloride, used to make plastisol, is considered environmentally not too safe. A certain popularity of metal tile of this kind is used only due to the fact that this polymer is distinguished by its high strength and serves for a very long time. The thickness of the plastisol is 200 μm.

The cost of metal, depending on the type of coating can vary between 150-250 rubles. Per square meter (for 2015).

Profile height

Roofing metal tiles, the standard dimensions of which are very convenient, can also differ in the height of the wave. The magnitude of this indicator depends primarily on the geometry of the profile, which can be different. The most popular forms of metal tile waves are:

• Monterrey. This is the most common variety. A profile of this type imitates clay tiles. The height of the waves in such sheets is usually 39 mm. There are also supermarket sheets on offer. This material has a slightly higher wave - 46 mm.

• Cascade. Metal tile of this type resembles a chocolate bar. The height of its profile is 25 mm. This is a very beautiful species, but it is also quite expensive. In particular, brown cascade sheets look great.

• Dune. The advantages of this variety are, first of all, the possibility of using hidden fasteners. On the roof, this material looks very solid and, in comparison with other types, quite original. In the metal tile of this variety, the height of the wave is 46.5 mm.

Metal roofing for complex roofs

To the broken roof today you can order a complete set of sheets with accessories. To do this, call an employee from the company specializing in the supply of this material. The professional will inspect the roof with the ordering. This will take into account such parameters as the complexity of the configuration, the features of the rafter system and the dimensions of the roof. Metal tile (and accessories to it in case of a call of the expert to search it is not necessary - that very conveniently) - the roof in installation very simple. However, placing it on broken roofs of unusual configuration in people without experience can still cause certain difficulties. Companies specializing in the supply of metal, usually provide services for its installation. Therefore, in this case it is worthwhile to think about the payment for mounting the sheets.

Than to cut

The sizes of metal roofing for the roof are selected by the manufacturers in such a way that it is as convenient as possible in the installation. In cutting with the installation on the roof, this material is almost not needed. However, sometimes it is still possible to cut it. Before performing this operation, you need to decide on the choice of tool. The fact is that the upper polymer layer of the sheets is very easily damaged. Therefore, for example, a Bulgarian can not cut them in any case. This tool heats the surface too much. In addition, from the circle when cutting metal sparks fly, also damaging the polymer layer. Cut metal tile usually with electric scissors. You can also use an electric jigsaw or a drill with a cricket nozzle.

Cutting rules

Cut material, therefore, should be correct, whatever the size of the metal. For a roof (the price of this material depends primarily on its length), a complex configuration sometimes cuts the sheets both in length and width. In the second case, when cutting, among other things, you should pay attention to the direction of the profile. Each sheet of metal has top and bottom. It is not possible to turn the material during installation.

The length of metal can be cut at every point. So, for example, the cut line should in no case pass through the region of the wave difference. If the cut is not done correctly, the sheet will simply not be installed on the roof afterwards, as it will be deformed.

The dimensions of the standard tile (length, thickness, width) are convenient for laying on any types of roofs. This is combined with cheapness and relative simplicity of cutting and makes the material so popular. Find the most suitable in this or that case, metal tile is quite simple. In extreme cases, you can refer to specialists who will make accurate measurements.
