Thanks to the rigidity of the Trislot grilles they are also used as walkways, bridges, ... for pedestrian traffic. A stainless steel surface, which is not slippery, hard to wear, which drains the rain and remove the dirt from the shoes and looks nice (and if slot is kept small is also heal proof) is the ideal flooring for different outdoor applications.
Trislot can make strength calculation if the grille has to carry a certain load over a certain span.
