Product Details

Structural Plywood

Description

Benson structural plywood is an engineered wood panel designed to be a high-strength sheet for use in general structural building and construction, subject to an application’s load bearing requirements. Commonly used as an un-treated panel, but it is also available in treated variant typically HS-S, H2 or H3. Made of selected range of gymnosperms & angiosperms specie timer, structural plywood is manufactured using type A phenolic adhesive. The product conforms to IS:10701 (2012).
