Compreg Plywood

Magnus compreg plywood is a premium grade ply which confirms to the standards of IS:3513 & manufactured under extremely high pressure in high tonnage hydraulic presses.
Application: The plywood has strong screw holding capability, used for making boxes for the heavy equipments, electrical transformers, fish storage boxes, marine decks & cabins etc. Compreg plywood can be used for manufacturing of pallets for industrial application and railway berths & seats etc.
