Forge-welded gratings

Gratings are fully resistance welded, by creating heat at the metal intersection points of square twisted or round crossbars and solid bearing bars. As the forging temperature is reached, the crossbars are pressed into the bearing bars under high pressure and the materials are forge-welded together. Forge-welded gratings have a high load-bearing capacity and, due to the twisted crossbars, a high slip-resistance. 

Continuous development at Lichtgitter has resulted in the most modern and advanced manufacturing facilities, ensuring the quality and accuracy of our forge-welded grating products which are of the highest possible standard.
