Welded wire mesh typically has larger openings than woven wire mesh. With the wire strands welded at each intersection, welded wire mesh is more capable of maintaining its shape when stressed.

Square welded wire mesh is the commonly used welded wire mesh. Other hole types include rectangle type, special type and so on. In general, square welded wire mesh is made of galvanized steel wire, zinc-coated steel wire, low carbon steel wire, PVC coated welded wire mesh and vinyl coated steel wire.
