Product Overview
What is Welded Wire Mesh?
Welded wire mesh is a metal wire screen composed of longitudinal and transverse wires welded together at their intersections using high-precision electrical resistance welding. This process creates a highly rigid, stable matrix that maintains its shape even under heavy load or cutting.
Unlike woven wire mesh, which can unweave at the edges, welded wire mesh offers exceptional structural integrity and uniform spacing. -
Common Specifications
Key Specifications: How to Read Mesh SizesWhen purchasing welded wire mesh from a manufacturer, you will need to specify four core metrics: Wire Diameter (Gauge), Mesh Opening Size, Surface Treatment, and Form (Roll or Panel).A. Wire Gauge (Diameter)Wire diameter determines the strength and flexibility of the mesh. It is typically measured in millimeters (mm) or **American Wire Gauge (AWG)** / **Standard Wire Gauge (SWG)**.* Light-duty:0.5mm to 1.5mm (used for garden fencing, chicken coops).* Medium-duty:1.5mm to 4.0mm (used for industrial cages, security partitioning).*Heavy-duty:4.0mm to 10mm+ (used for concrete reinforcement panels).B. Mesh Opening SizeThe opening size (or aperture) is the distance between two parallel wires, measured from center-to-center or inside-to-inside. Common opening sizes include:* Small apertures:1/4" x 1/4", 1/2" x 1/2", 1" x 1" (ideal for pest control and animal cages).* Medium apertures:2" x 2", 2" x 4", 4" x 4" (standard for boundary fencing and racking).* Large apertures: 6" x 6", 8" x 8" (primarily used for heavy construction reinforcement).Materials and Surface CoatingsThe lifespan of your wire mesh heavily depends on the environmental conditions it faces. Manufacturers generally categorize welded wire mesh into four primary material types based on their surface treatments and corrosion resistance:Galvanized Before Welded (GBW)GBW mesh offers moderate corrosion resistance and is best suited for controlled indoor environments or temporary outdoor structures, such as temporary safety fencing. Because of its production sequence, it typically has a short to medium lifespan when exposed to the elements.Galvanized After Welded (GAW)GAW mesh provides high corrosion resistance, making it the industry standard for permanent outdoor fencing, agricultural enclosures, and livestock pens. Thanks to the post-weld protective layer, it boasts a long operational lifespan, successfully enduring harsh weather conditions.PVC / Vinyl CoatedFor projects requiring both excellent corrosion resistance and visual appeal, PVC or vinyl-coated mesh is the ideal choice. It is highly recommended for coastal environments with high salt exposure, landscaping, and architectural designs. The thick polymer coating ensures a very long lifespan and prevents scraping or peeling.Stainless Steel (Grade 304 / 316)Stainless steel mesh delivers the maximum level of protection against rust and chemical degradation. It is widely used in highly demanding sectors like chemical processing plants, food production facilities, and marine engineering. While it requires a higher initial investment, it offers a virtually permanent solution. -
Application Area
Top Applications of Welded Wire MeshBecause it can be customized from ultra-fine screen to heavy steel rebar mesh, its industrial footprint is massive.Construction & Concrete ReinforcementIn construction, heavy-duty welded panels (often called BRC mesh) are embedded into concrete slabs, roadways, and retaining walls. The mesh absorbs tensile stresses, preventing the concrete from cracking or shearing under heavy traffic.Security Fencing & Machine GuardsMedium-gauge mesh panels are highly popular for high-security perimeter fencing around warehouses, data centers, and military zones. In manufacturing, it is fabricated into machine guards to protect operators from moving parts while maintaining visibility and ventilation.Agriculture & Animal EnclosuresFrom large cattle fencing to micro-mesh chicken wire and aviary cages, welded mesh provides secure barriers that predators cannot easily chew through or break. Greenhouses also utilize it for custom plant support benches.As a leading welded wire mesh manufacturer, we supply an extensive inventory of customizable options—ranging from light rolls for agricultural distribution to heavy-duty structural panels certified for civil engine -
