basic information
● The two-layer plywood tread has a high soundproofing effect and is lightweight. The two-layer plywood tread, made by spot welding 2.0 mm thick steel plates, has excellent soundproofing properties and quiet walking sounds. Additionally, it has increased rigidity due to bending processing, making it lightweight and high-strength. ● It also performs well as a temporary staircase. The steps are flat and easy to walk on, and water does not accumulate. Furthermore, it has excellent wear resistance for temporary use, ensuring a safe and easy working passage. ● Finishing work is also easy and can be done reliably. Since the surface of the steps is made of steel plates, it is easy to adjust the substrate for floor finishing materials, and adhesion can be done securely. ● The landing is flat on the underside as well. The flat structure on the underside enhances its aesthetic appeal.
