Welded wire mesh, or wire cloth is typically made from galvanized wire mesh or plastic/vinyl coated welded wire mesh. This mesh is most commonly made of iron or steel wire, but any metal that is malleable may be used.
Welded mesh is used as an alternative to woven mesh and typically has larger weave openings per linear inch. Welded mesh offers a flat surface which maintains a firm structure and can provide support or protection to other goods. Common uses for welded wire mesh, or steel mesh include: fencing panels, wire partitions, wire container panels, wire baskets, animal cages, enclosure works, screens, security panels, shelving, signage, stairways/treads, fishing traps and concrete reinforcement.
In the process of fabricating welded wire mesh, the wires are resistance welded together at their intersections using electrical power and cut into rolls or flat panels of the desired sizes. It is then either constructed into smaller industrial products, or used for applications such as fencing or reinforcement.
Variables such as material choice and finishing or coating will be adjusted according to the intended application of the wire mesh and the environment to which it will be exposed. Wire mesh that has been welded is generally available 4 different ways—galvanized, hot dipped galvanized, PVC coated or made of stainless steel. Types of materials commonly used for wire mesh include steel, stainless steel, brass, aluminum and more.
Steel and stainless steel are popular in many applications due to the strength and durability of steel, as well as its heat resistance. Furthermore, stainless steel is corrosion resistant which allows the material to be used in applications where exposure to moisture is a factor. Compared to the other types, stainless steel wire mesh is the most expensive but also the strongest and longest lasting option. It is mostly used in industrial settings, and makes up the majority of material used for fencing systems.
Wire mesh can be adapted fairly easily to suit different applications and can changes in terms of mesh sizes, configuration, wire gauges and finish. Galvanizing is recommended, especially for heavy duty applications, as it greatly increases the strength of the wire mesh and protects the metal from environmental factors. Computer controlled welding equipment can be used and is advantageous for applications in which mesh opening accuracy is a factor.
