BWP Grade Marine Plywood
Premium plywood manufactured from selected and well-peeled veneers. A specially formulated phenolic resin of rich soil content conforming to standard of IS:848:1974 gives immense inner strength to this plywood. This plywood is extensively used in the construction, repair and maintenance of marine and river crafts. Premium marine plywood given permanent preservation chemical treatment by vacuum pressure impregnation to made the product insects, borerm tramiters and fungi free.
