The profile wires are connected to the crossbars by means of high pressure resistance welding. So this construction of the whole segment is slot secure and high resistant. Individual parameters for the production are computer-controlled at the welding machine.

Permanent verification of individual parameters, such as the level of welding current, leads to safe-guarding a constant quality combined with high mechanical stability.

The triangular shape of the slot performing wires practically excludes the clogging of individual slots.The downward widening slot in flow direction prevents blockage of near-mesh grain size particles.
