FORGE-WELDED GRATINGS BY PROMETALL

Forge-welded gratings are produced by pressing twisted square rods (or round rods) that take on the function of the cross bar, into the supporting bar with high pressure AND simultaneously welding them electrically by means of the resistance welding procedure. The result: outstanding, static characteristics and high resilience.
