Strength and Stability for Demanding Outdoor Projects
Not every sheet of plywood is up to the task. Some buckle under pressure. Others look the part but can’t handle the weather. That’s why, when a project really matters, the choice of material makes all the difference.
That’s why DMK Forest Products supplies WISA® S/BB Birch E0 Exterior Plywood. Built from fine birch veneers, it offers a clean S face, a robust BB reverse, and the reassurance of Group 3 fire certification. It’s tough, reliable, and ready for shipbuilding, construction, vehicle flooring, and jobs where there’s no room for compromise in demanding conditions.
