Introduction
Welded wire mesh is a widely used metal fabric known for its strength, stability, and versatility. It is manufactured by welding intersecting steel wires at their crossing points, forming a rigid and uniform grid structure. Compared with woven wire mesh, welded wire mesh offers better load-bearing capacity, dimensional accuracy, and long-term durability.
Due to these advantages, welded wire mesh is extensively applied in construction, agriculture, security fencing, industrial protection, and architectural design. This article provides a comprehensive overview of its types, benefits, materials, manufacturing methods, and applications.
Chapter 1: What is Welded Wire Mesh?
Welded wire mesh is a prefabricated metal grid made by electrically welding longitudinal and transverse wires together at regular intervals. Each intersection is permanently bonded, creating a strong and stable structure.
The mesh is typically produced in rolls or rigid panels and can be customized in terms of wire diameter, mesh opening, sheet size, and surface treatment. Common materials include carbon steel, stainless steel, and aluminum.
Unlike woven mesh, welded wire mesh does not shift or unravel, making it suitable for structural and safety-critical applications.
Chapter 2: What Are the Different Types of Welded Wire Mesh?
Square Welded Wire Mesh
Square welded wire mesh features equal spacing in both directions, forming square openings. It provides balanced strength and is commonly used in fencing, concrete reinforcement, and safety barriers.
Rectangular Welded Wire Mesh
Rectangular welded mesh has elongated openings that provide higher strength in one direction. It is often used in shelves, partitions, and construction reinforcement systems.
PVC Welded Wire Mesh
PVC welded wire mesh is coated with a plastic layer over galvanized wire. This coating improves corrosion resistance, weather durability, and visual appearance. It is widely used in gardens, residential fencing, and animal enclosures.
Galvanized Welded Wire Mesh
Galvanized welded wire mesh is coated with zinc to prevent rust and oxidation. It is suitable for outdoor and humid environments and is available in hot-dip and electro-galvanized forms.
Welded Stainless Steel Wire Mesh
Stainless steel welded mesh is manufactured from grades such as 304 and 316 stainless steel. It offers excellent resistance to corrosion, chemicals, and high temperatures, making it ideal for food, pharmaceutical, and marine applications.
Welded Wire Fencing
Welded wire fencing is designed for perimeter protection and boundary control. It combines welded mesh panels with steel posts to create durable fencing systems for residential, commercial, and industrial sites.
Heavy Welded Wire Mesh
Heavy welded wire mesh uses thick wire diameters and reinforced welding techniques. It is suitable for high-load and high-security applications such as mining protection and industrial safety barriers.
