Spot welded mesh

Spot welding grids are made from smooth, drawn steel or stainless steel wires. The wires are laid on top of one another in such a way that a rectangular grid is created and welded at the crossing points by means of resistance welding. As a result of the welding, the crossing points - in contrast to wire mesh - cannot be moved or rotated and the spot welding grid is therefore very rigid.

Spot welding grids are described by mesh size (square or rectangular), wire thickness, material (stainless steel, steel, galvanized steel, plastic-coated steel) and edge design (open or closed mesh).

The usual production sizes are rolls one meter wide and 25 meters long. Larger formats are usually produced as sheet goods.

Spot welded meshes are used, among other things, when wire mesh is not sufficiently stiff, or for dimensionally stable structures such as bird aviaries , shopping carts , shopping and bicycle baskets.

The production criteria for spot welded meshes are specified in DIN ISO 4783-3 (formerly DIN 4192-1).
