| Mechanical properties |
The stair will be able to support a uniformly distributed load of 500 Kg/m2 on the flights (on the surface projected on the horizontal plane) and landings as well as a point load of 200 Kg applied anywhere on the steps or landing deck (standards NBN 1-50 and NFP 06-001). The guardrails will withstand a horizontally applied uniform load of 100 Kg/m without permanent deformation (standards NBN 03-103, NFP 06-001 and NFP 01-012). |
