Press locked Grating

Press locked Grating

Product information

The press locked grating is the most commonly used type of grating in many European countries today. Thanks to a production technology which differs significantly from that used for the press welded grating, and which enables a much greater variety of products, this type of grating provides for an almost unlimited number of applications. Its design allows for great flexibility regarding the mesh size and the height and thickness of the bearing bars. In combination with the variety of materials from which press locked grating can be manufactured, we produce grating that are exactly in line with the customer‘s wishes and the intended use. We do not claim that the press locked grating is the better grating, but it is certainly the more attractive and individually customised grating compared to the press welded grating.

For a press locked grating, the cross bars – which as a rule are made of cold-rolled flat steel – are pressed into the previously punched-out bearing bars. The banding bars are designed as T-shaped or flat sections, and are attached by means of automatic resistance welding. If there is an increased risk of slipping, press locked grating can be manufactured in an anti-skid design. For this, the bearing and/or cross bars are notched on the upper side. With press locked grating, the opposite end meshes are usually of equal size. But here, too, applies what has been said above: there is almost no limit to the imaginable uses and designs of press locked grating.
