The straight Graepel-Perl stair tread is made of hot-dip galvanized steel (DD 11) with a welded edge at the front. The surface is closed and features small, semi-spherical, upward-facing embossments which make the step slip resistant. The step is suitable for use in public areas, especially in interiors where dirt should not fall through, but a certain degree of slip resistance is necessary. The step can be walked on with soft shoes, but also barefoot. It is designed for a uniformly distributed load of 5 kN/m² and a concentrated load of 1.5 kN for 200 x 200 mm.
The material thickness is 2.5 mm. The step is 70 mm high. Different lengths and widths are available. The hole width is 120 mm for a step width of 240 mm, 150 mm for a width of 270 mm. Other dimensions on request.
