Wigman Fabricate Birch fire-retardant plywood is a fine-grained material apt for cabinetry, shelving, and constructing fixtures like drawers and desks. Its ability to slow down flames and resistance to bending and warping over time make it a great wood substitute. The surface and make of birch ply is sturdy, and it’s easy to fasten it together using screws that hold firm due to hollow-free compactness.
