Square Edged OSB3 board is a multilayer board made of micro-veneers. The unique formation of the OSB3 sterling board allowed it to withstand high-stress levels and approved for load-bearing construction. As a result, the panels are incredibly versatile and robust; they commonly used in structural application and as a general-purpose alternative to plywood. The BBA classification of these boards permits use in high humidity, roofing, flooring applications, wall sheathing, and timber frame houses. Our OSB3 sheets supplied by the world’s leading manufacturers of wood-based panels.
