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 that 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.
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 in 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.
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.
Wire mesh can be adapted fairly easily to suit different applications and can change 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.
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 the material used for fencing systems.
