Corà's plywood panels are used for: furniture, packing, ship-building, coach-building, flooring foundations and supports, etc., and are availa-ble for delivery direct from the docks or in small quantities from the warehouse. The Wood reassembled into thin layers was first used by the Egyptians and then the Romans, so plywood and multi-layer pan-els have been around since ancient times. It is a well-known fact that their durability depends on various factors, one of which being the spe-cies of wood. Increased durability results from using selected wood types, or using the right chemical protection treatment. One of the most important physical properties of plywood is its density, which depends on the percentage of adhesive used to glue the layers together and on the pressure exerted by the presses during assembly. Generally, the density of the plywood is higher than that of the wood used to make it.
