The Spiral stairway step Graepel-Rubber stud with a welded pillar can be directly attached to a central stair pillar. With its design of steel (DD 11) and subsequent hot-dip galvanizing, it is suitable for the use in industrial areas. It is designed for a uniformly distributed load of 5 kN/m², a concentrated load of 1.5 kN on 200 x 200 mm, and it complies with DIN EN ISO 1461. The scope of supply includes the step pin with screws.
The surface is dominated by rubber studs providing anti-slip and sound insulating properties, thus making this step a base for silent walking. The rubber studs (black as standard colour) are supplied loosely and have to be driven in by the customer. On request, red rubber studs are also available, for example to optically highlight step edges.
The material thickness is 2.5 mm. The perforation or embossing runs parallel to the edge. The edges are welded. The spiral stairway step can be delivered for staircases with left-hand or right-hand direction and for different stair radii and pillar diameters.
