kN/m² is a unit that indicates the load a structure must be able to carry. It describes how much weight the grating can ultimately support. In kN/m², a uniformly distributed load, a point load, or a line load can be specified. As you can imagine, a traffic application requires a different load capacity than pedestrian use. You are free to enter a value here; if you are unsure, we can always get in touch to advise you.

The clear span is the span minus the support.
