The design of these innovative interior stairs is perfect in the light-flooded stairwell of a modern residential building. The striking central stringer made of a steel tube is the load-bearing component. It contrasts appealingly with the transparent glass treads. The overall screen printing on the tread surface prevents people from slipping and from seeing through the treads. They are made of three-layer laminated safety glass. Steel and glass combine perfectly with stainless steel and harmoniously integrate the interior stairs structure into the stylish interior.
