Sizes of polycarbonate. Standard sizes and technical specifications of polycarbonate sheets

Polycarbonate is a modern building material used mainly for the construction of greenhouses, sheds, canopies and fences. There are only two main varieties of it, differing only in the design of sheets. When buying this material should pay attention to such parameters as dimensions, thickness and weight.

How polycarbonate is made

This material is produced in several stages:

  • The carbonate granules entering the enterprises in bags are thoroughly cleaned and sorted.
  • Next, they are sent to the smelter. Various additives are added to the liquid carbonate mixture to improve the quality of the finished material.
  • The resulting mass in a special installation is formed into a monolithic or cellular plate of a given thickness.
  • After cooling the material is cutting sheets.
  • Apply a sunscreen.
  • Ready polycarbonate is sent to the warehouse.

Colored sheets are made from colored granules. The entire manufacturing procedure is performed on a single extrusion line. On such a modern equipment in a minute you can make about 5 m of material. Of course, the more modern the line, the better the polycarbonate is obtained. The price for it also depends on the complexity of the production process.polycarbonate dimensions

Polycarbonate Varieties

Actually polycarbonate is called special sheets, characterized by such qualities as flexibility, elasticity, transparency and durability. The color of this material can be very different, just like the thickness. There are only two main types of polycarbonate: cellular and monolithic. The first one is cheaper and has a special cellular structure. This means that between the two thin sheets are located cross-bridges, forming something similar to the honeycomb. Hence the name of the material. Monolithic polycarbonate looks like ordinary glass.

Standard sizes of polycarbonate honeycomb

Currently, the building stores are selling cellular sheets with an area of ​​2100x6000 and 2100x12000 mm. Their thickness may be different. The most common options are 3, 4, 6, 8, 10 and 16 mm.

Thin material is mainly used to replace glass - in windows, in the manufacture of interior parts, signage, etc. Thicker sheets, for example, 8 mm polycarbonate, are used to build various kinds of enclosing structures - gazebos and porches, fences, etc D. Even more "solid" sheets are used for the manufacture of various kinds of structures, in the process of operation are experiencing serious loads. It can be, for example, visors of porches, roofs of greenhouses, etc.polycarbonate sheet

Polycarbonate weight

The size of polycarbonate honeycomb is not the only parameter that you should pay attention to when buying. Be sure to ask how much weight sheets. The fact is that in some cases, manufacturers smelt material with very thin internal partitions (cell walls). This reduces the cost of polycarbonate, and hence the market price for it. However, such sheets are less durable than standard ones.It is not recommended to use them in responsible construction. It is advisable to apply such material only in the southern regions of the country, where in winter, too much snow loads do not act on the polycarbonate structure.

Of course, the weight of polycarbonate depends on its thickness. The table below shows the standard ratios for some material options.

Sheet lightweight polycarbonate is usually marked with the word Light. But some manufacturers ignore regulations and give such material as standard. Therefore, when buying you need to be extremely attentive. Sheets should not be too soft.

Sheet structure

Cell polycarbonate can have a different structure. The most popular on the market sheets:

  • with single chamber structure,
  • two-chamber,
  • four-chamber.

Also in our time produced a special reinforced polycarbonate with jumpers located diagonally. These sheets are different from the usual lower flexibility and greater density.polycarbonate Price

Bending radius

This is a very important indicator, which is also taken into account in the construction of structures.Cellular polycarbonate - a material often used for assembling arched, curved and even spherical structures. Meanwhile, whatever the size of polycarbonate, sheets can be bent only up to a certain limit. The table below shows the maximum allowable radius for standard polycarbonate of different thickness.

Dimensions of monolithic material

Standard sizes of polycarbonate of this variety are 20050 x 3050 mm. Their thickness can vary between 2-12 mm. The light transmission ability of a monolithic polycarbonate is higher than that of a cellular one, and it looks much more effective. However, this material is more expensive.

In addition, sheets of monolithic polycarbonate can be single-layered or multi-layered. On the market there is not only color, but also toned, as well as cramped material. The latter type is especially good for creating all sorts of decorative elements of interior and landscape design. Embossing can be done, for example, under the "sand", "skin", "drop", etc.polycarbonate 8 mm

As you can see, both cellular and monolithic materials are very well suited for the assembly of decorative courtyards and gardens. Polycarbonate, whose characteristics allow you to build practical greenhouses, beautiful gazebos and verandas, is durable, retains heat well enough and is almost perfectly transparent.

Polycarbonate: price

The cost of polycarbonate depends primarily on its thickness. Also, factors such as the manufacturer, weight, distance of the region from the place of production, etc. can influence the price. For example, the “Actual” material is usually more expensive than Polyplast polycarbonate.

Thus, cellular material with a thickness of 4 mm can be sold for 2000-3500 rubles. For polycarbonate 8 mm will have to pay at least 5 thousand. The cost of monolithic sheets depends on the same characteristics. For example, a sheet of 2 mm costs approximately 4,500–5,000 rubles, 3 mm — 8,500 rubles, and so on.

Lifetime

Most modern manufacturers of both cellular and monolithic polycarbonate give a guarantee for their products in 10 years. That is, during this time the sheets will not lose their attractive appearance, and all their characteristics will remain at the same level. In practice, this material can be exploited for about 25 years. Consequently, sheets of monolithic polycarbonate, as well as cellular, can be used for the construction and permanent structures.
