Welded wire mesh, commonly referred to as weldmesh, is a grid of intersecting metal wires that are welded together at each intersection. It's typically made of steel wire, though other materials like stainless steel, galvanized steel, or PVC-coated steel can also be used depending on the application.

Basics of Weldmesh:

1. Construction: Weldmesh is constructed by welding together longitudinal and transverse wires at their intersection points. The process creates a strong and durable mesh structure.
2. Wire Gauge and Mesh Size: The thickness of the wires used and the spacing between them determine the gauge and mesh size of the weldmesh. These specifications can vary widely depending on the intended application.
3. Types of Welds: Weldmesh can be produced using different welding techniques such as spot welding or electric resistance welding. The choice of welding method affects the strength and durability of the mesh.
4. Surface Finish: Weldmesh can have various surface finishes, including plain (uncoated), galvanized (coated with a layer of zinc for corrosion resistance), or PVC-coated (to provide additional protection against corrosion and improve aesthetics).

Applications of Weldmesh:

1. Construction: Weldmesh is commonly used in construction for reinforcing concrete structures such as floors, walls, and pavements. It provides tensile strength to the concrete and helps prevent cracking.
2. Fencing and Enclosures: Weldmesh is extensively used for fencing purposes, including perimeter fencing for residential, commercial, and industrial properties. It offers security and boundary demarcation while allowing visibility and airflow.
3. Animal Enclosures: Weldmesh is used in the construction of animal cages, enclosures, and runs for pets, livestock, and poultry. It provides containment while allowing for ventilation and visibility.
4. Industrial Applications: Weldmesh finds applications in various industrial settings, including machine guards, safety barriers, shelving, and storage racks. Its strength and durability make it suitable for heavy-duty usage.
5. Agriculture and Horticulture: In agriculture, weldmesh is used for constructing trellises, plant supports, and fencing for crop protection. In horticulture, it's used for greenhouse structures, screening, and plant protection.
6. Gabions and Retaining Walls: Weldmesh is employed in the construction of gabion baskets used for erosion control, slope stabilization, and retaining walls. It allows for drainage while providing structural stability.
7. DIY and Crafts: Weldmesh is popular among DIY enthusiasts for various projects such as garden trellises, wire sculptures, and art installations due to its versatility and ease of manipulation.

Weldmesh offers a cost-effective solution for a wide range of applications due to its strength, durability, and versatility. The specific requirements of each application will dictate the choice of wire gauge, mesh size, and surface finish.
