Product Overview
BS1088-certified marine-grade plywood sheet, measuring 2440mm x 1220mm (8' x 4') with an 18mm thickness.
Made from durable tropical hardwood veneers and bonded with waterproof adhesive, it resists swelling, warping, delamination, and rot even under prolonged moisture exposure.
Unlike standard plywood, it contains no core voids, preventing water entrapment and improving overall strength.
Widely used for hull planking, flooring, and heavy-duty marine construction, the solid hardwood face is pre-sanded and can be left natural, stained, or varnished.
