Straight stair tread
The Graepel-Indoor straight stair tread can be walked on safely and comfortably even in delicate footwear and is intended for indoor use, as it does not have drainage holes. If drainage is necessary, the Graepel-City tread is recommended.
The surface consists of small holes punched upward (d=4 mm), which provide slip resistance. Due to the small hole diameter, the Graepel-Indoor is suitable for use in public areas, particularly where nothing is allowed to fall through and a view downward is not desired. The step 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 are available upon request.
