| Magnus marine plywood is specially treated plywood that is designed to resist rotting in a high-moisture environment. It is manufactured with utmost care in 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. Application: Extensively used in making of furniture, partitions, racks/shelves, shutters, under layer for decorative laminates etc. Size (In feet): 6×3, 7×3, 8×3, 6×4, 7×4, 8×4, 7×5, 8×5 Thickness: 4, 6, 8, 12, 15, 18, 25 mm
