USB plywood is moisture resistant type of oriented strand board. The characteristics and dimensions of USB sheets allow the material to be used in construction, repair, and facilitate its use when creating containers for the transportation of bulky goods. The multilayer structure gives them a higher strength than chipboard, and a special impregnation allows you to protect the surface from the influence of atmospheric factors.

The USB name cannot be considered official - rather, it is a distorted version of OSB, this is how oriented strand board is marked... USB plywood is sometimes referred to as its universal variety, but the characteristics of the material are no different from the usual version. OSB is produced in the form of large-format sheets or, as they are also called, plates. This type of plywood does not have a solid structure, but consists of wood chips, interconnected by layers using glue based on natural or synthetic resins.

For USB-lists it is typical high density and strength. Usually the slab consists of 3-4 layers, in each of which thin chips are glued together and with the previous layer. For the connection, resins are used mixed with boric acid and synthetic wax. These materials are called oriented because their layers have a multidirectional structure: the outer ones are directed longitudinally, the inner ones are transverse.

This makes it possible to significantly strengthen the material, to give it increased resistance to mechanical stress.
