Straight stair tread
The Graepel-City straight stair tread is safe and comfortable to walk on, even in delicate footwear, and can be used both indoors and outdoors. The surface consists of small holes punched upward (d=4 mm) and downward (d=8 mm), arranged alternately. The open area is approximately 6%, giving this stair tread a certain degree of slip resistance and displacement, as well as good drainage properties.
Due to its small hole diameter, it is suitable for use in public areas and is designed for a uniform load of 5 kN/m² and a point load of 1.5 kN over a 200 x 200 mm area.
It is supplied as standard in hot-dip galvanized steel (DD 11) with a welded edge on the front side. Other materials and dimensions available upon request.
