Gratings are robust constructions which are constructed in grid form. The components can be used in many ways, for example, for constructing stairs, stages, podiums and in many other areas. The fact that the gratings have a high level of stability and are also very resistant to different weather conditions is particularly advantageous. In most cases, they are made of galvanized steel, by putting together a number of intersecting flat profiles by welding or pressing. When constructing it, it is important that the correct screws are used. At least four screw connections should be attached.
