Press Lock Gratings

Press locked gratings are usually made of steel, stainless steel or aluminium. However, other materials can be used if the customer so wishes. On our computer controlled production lines, the bearing bars are notched then pressed and locked with the non-attenuated cross bar at very high pressure.
This particular production method guarantees a uniform precision mesh size. The edge of the press locked gratings is banded either with T-shaped special section or flat bar. This process — i.e. where the banding is welded at right angles to and flush with the grating surface — is effected on an automatic bordering machine via resistance welding. For those applications in areas where there is a danger of skidding or slipping, we recommend bearing bars and cross bars in the anti-skid design.
