Heavy-duty gratings are produced using an U-profile or flat steel edging and are then hot dip galvanized. Please make use of our free-of-charge consulting services.

*Bridge class = Total weight of the vehicle.

** Cube load = Load application surface.

If the track contains components that are particularly delicate (e,g, parts of track transitions, gratings or such like) then the wheel loads which are allotted to the individual parts, are to be multiplied by 1.4 of the brake loads.
