What is Welded Wire Mesh?
Welded wire mesh is manufactured by electrically welding intersecting wires at their junction points, creating a rigid grid structure with exceptional strength and consistency. This manufacturing process produces mesh with uniform square or rectangular openings, where each intersection is permanently bonded through resistance welding.
The welding process ensures that the mesh maintains its shape and structural integrity under load, making it ideal for applications requiring dimensional stability and consistent performance.
Manufacturing Process
- Wire Preparation: High-quality steel wires are drawn to precise diameters and cleaned to remove surface contaminants. Galvanized wire may be used for corrosion resistance.
- Mesh Formation: Automated welding machines precisely position longitudinal and transverse wires at specified intervals. Multiple wire rows create the mesh pattern.
- Welding: High-frequency electrical current melts wire intersections, creating strong metallurgical bonds. Modern machines weld at rates of 60-120 intersections per second.
- Flatening and Cutting: Welded sheets are flattened under pressure and cut to standard or custom dimensions.
- Surface Treatment (Optional): Additional galvanizing, PVC coating, or other treatments applied as specified.
- Quality Control: Each batch tested for weld strength, wire spacing, and dimensional accuracy.
