Material Safety Data Sheet (MSDS) Customer Service. Monday-Saturday ... Baltic Birch Plywood ... We stock the sheets in whole 5'x5' dimensions, but shipping ... We stock our own Boise Cascade manufactured plywood and other leading brands. Available in fir and southern pine as well as other desired imported species. Our product mix includes sheathing, flooring, sanded, siding, plyform and insulating panels. Cover the stack loosely with plastic sheets or tarps. Anchor the covering at the top of the stack, but keep it open and away from the sides and bottom to ensure good ventilation. Tight coverings prevent air circulation and when exposed to sunlight, may promote mold or mildew. Doka multi-ply formwork sheets are used in very many Doka formwork systems. The broad spectrum – ranging from DokaPly to the Xlife sheet – allows Doka to offer ideal solutions for many different requirements and cater for anything from infill zones to fair-faced concrete.
