Fast growing road transport imposes usage of heavy duty materials on trailers’ manufacturers. One of these materials is plywood, which has quite good durability in relations to its thickness. Basic type of plywood used for production of trailers is anti-slip plywood covering their floors. For truck sides and special developments e.g. mobile service stations melamine coated plywood is one of best materials. On the other hand, raw plywood is used for wall fillings or wall protection.
