Sym-Ply is a hand-ganged, imperial clamp forming system rated at 1500 psf designed for use in forming foundations, columns, shear walls, retaining walls, crash walls, abutment and retaining walls, and elevator and stair cores. Built with high-strength, low-alloy 80-ksi steel, the durable, lightweight system withstands typical form pressures. Panels feature a grid pattern design of the cross-members, which is an efficient way of distributing the concrete pressure to the rails and ties. Profiled side rails allow contractors pry bar access and easy gang adjustment to the chalk line. Accessory connections are fully integrated to eliminate loose hardware.
