Wire mesh sheet is a highly versatile product used for a wide variety of applications, from safety fencing, concrete reinforcement, light fixtures, to air filtration. Wire mesh can be made of many different metals – such as carbon steel or stainless steel – with a range of gauges and hole sizes.
Wire mesh comes in two basic types: woven wire mesh and welded wire mesh.
Both types of mesh begin with extruding a metal rod, tube or wire through a number of dies that are successively smaller to create a thinner wire which is then wound on a spool. The wound wire later can be run through a straightening machine and cut in desired lengths for the next part of the process.
Woven wire meshWeaving wire into mesh is similar to the process of weaving cloth. First, a wire loom is set up with long lengths of wire strung parallel through the machine like yarn warp threads.
As the machine operates, wire harnesses lift alternate strands of the wire, allowing a shuttle to pass between strands perpendicularly, pulling along a filling wire, similar to a yarn weft. Then a batten presses the filling wire against the mesh and the harnesses lift the opposite strands so the shuttle can pass through in the opposite direction, producing an over-under weave.
Other weave patterns can also be created.
Welded wire mesh
Another type of wire mesh, sometimes called welded wire fabric, can be made with an automatic wire welding machine. This type of mesh consists of a series of parallel and perpendicular wires spaced at equal distances and welded at the intersections.
To set up the machine, wire is strung through a row of automatic feeders that push the long parallel strands through the welder. To create the cross-wires, another feeder drops short perpendicular sections of wire down on top of the parallel wires. At the intersections between parallel and perpendicular wire, a row of electrical resistance weld heads then fuses the joints and the mesh is pulled ahead, while another perpendicular wire drops down.
