At Armstrong Cheshire, we supply high-quality 12mm marine ply that meets BS1088 standards for strength and weather resistance. Each plywood sheet is made from untreated tropical hardwood veneers and bonded with Weather and Boil Proof (WBP) adhesive for long-term durability. With a multi-ply core and no core gaps, this ply sheet performs reliably in environments with repeated exposure to moisture. Ideal for construction, joinery, and other demanding applications, our 12mm marine plywood is responsibly sourced from managed forests. Finished in a natural wood appearance, it’s suitable for indoor and outdoor use. Please note that cut sizes may vary slightly due to blade width. For any enquiries, please contact our Sales Team.
