What it is plywood sheet: manufacturing features

plywood sheet is a plate of glued wood veneer layers 3-5. Produce it from different types of wood - hardwood (birch, alder, oak) and softwood (pine). The most high-quality and therefore expensive is considered Birch plywood, the cheapest - from coniferous trees. To reduce the cost of the final product, often combine different types of wood. For example, veneer deciduous trees are used for the inner layers of the plywood, coniferous and - external. This is done not only in order to save. The outer layer of cedar veneers are used to give a sheet of plywood beautiful pattern.

In the manufacture of plywood with special trunk sawing machine is removed by the helical thin sheets (veneer). These sheets were stacked on one another (usually perpendicular to the grain to impart greater strength material) and then pressed under great pressure into monolithic units. Many types of wood do not need a special adhesive impregnation. However, often used to improve the characteristics of special natural or synthetic compounds.

In accordance with the GOST providing 4 grade plywood. On sheets of first grade plywood allowed to have minimal defects. In the second grade plywood may be present areas subjected repairing cracks, leakage of adhesive. Third grade presupposes knots on the surface of wormholes, but the total number of defects should not exceed 9. fourth grade plywood has a very poor quality and has a large number of defects (knots fused, a large number of wormholes is uneven edge). It is used mainly for the manufacture of packaging.

Interesting fact! On the industrial scale production of plywood was delivered at the end of the 19th century, and a method in which a sheet of plywood glued together from several layers of veneer, called the Russian, it is in Russia was invented method of producing shelled plywood and machine for its implementation.

The main types of plywood presented in domestic market

There are several main types of plywood. They are all different in their characteristics and applications. Vary as the size of the veneer and the thickness thereof. All these characteristics determine how much a sheet of plywood:

  • FC plywood (plywood moisture resistant.) The advantage of this kind of plywood is environmentally friendly. In its manufacture the adhesives based on urea, natural chemical compounds that allows the use of this material even for finishing premises, in the manufacture of furniture and vessels, in the automotive industry. This plywood is durable and ease of handling. A major drawback is the average water resistance. Plywood FC produced in polished and polished form;

Useful advice! Depending on how the fibers are arranged (along or across the front layer), separated longitudinal and transverse plywood. Which can be determined by the marking. If it is the second type, when specifying the veneer size put on top width (e.g., 1525 × 3050 mm).

GOST standard veneer length is 2440 mm and width - of 1220 mm. However, among the most popular formats relates 1525 × 1525 mm.

plywood veneer thickness is determined by the thickness and number of layers. To date, no single accepted standard, and from different manufacturers sheet thickness varies significantly. The minimum thickness of plywood provided in shops, is 1.6 cm, the maximum - 7.6 cm.

The thickness of the veneer can vary from 16 to 76 mm

Price per sheet of plywood is dependent on many factors: the type of plywood used in the manufacture of wood products, the material grade, size, thickness.

Wholesale price per sheet of waterproof plywood 10 mm ranges from 309 to 560 rubles (contains price per sheet of plywood 10 mm 1525 × 1525 mm). If the size of 12 mm plywood sheet it costs from 371 to 505 rubles. Wholesale price per sheet of plywood 18 mm 1525 mm × 1525 averages from 536 to 1182 rubles.

In plywood sheet size and the price is slightly different from previous types. Thus, at a thickness of 18 mm price per sheet is approximately 1580 rubles, 21 mm - 1845 rubles. It often occurs and the size of 10 mm plywood sheet, 12 mm and 15 mm.

The price of various types of plywood may differ depending on the region.
