Black Marine Ply Wood

Marine PlywoodMarine Plywood manufactured by P.R. Industries is specially treated plywood that is designed to resist rotting in a high moisture environment. Marine plywood is manufactured with utmost care inn the supervision of technical experts with well selected pieces of core and face veneers. Further the finished plywood is subjected to proper chemical treatment with water soluble fixed type preservatives under vacuum pressure to ensure protection against wood destroying organism and to make the product insects borer termites and fungi free. This specific stress relieving is also given to check anti properties of plywood which make them dimensionally stable in both excessive wet and dry condition throughout its life.
