Straight stair tread
The Graepel-Special 4-18 straight stair tread is suitable for industrial applications. It is designed for a uniform load of 5 kN/m² and a point load of 1.5 kN on a 200 x 200 mm area. The surface features holes oriented upward (d = 4 mm) and downward (d = 18 mm) in staggered rows. The open area is approximately 21%.
The step offers good slip resistance and, due to the large perforations, also provides excellent drainage. The step appears relatively transparent and allows for a certain degree of visibility.
It is supplied as standard in hot-dip galvanized steel (DD 11) with a welded edge on the front side. Other materials and dimensions are available upon request.
