Welded Wire Mesh
Welded wire mesh, also known as welded net or spot-welded mesh, is a mesh material fabricated by vertically arranging metal wires in warp and weft directions and joining the intersections of horizontal and vertical wires through resistance spot welding. As a mass-produced metal mesh, it combines toughness with structural strength and can be directly cut, bent, or welded into various deep-processing products.
Mainstream material
Stainless steel welded mesh (304/316L), resistant to rust and corrosion, specifically designed for food processing, aquaculture, filtration, and equipment protection; 316L grade exhibits resistance to seawater and chemical chloride ion corrosion.
Hot-dip galvanized welded mesh
Fabricated by welding low-carbon steel wires and then undergoing full hot-dip galvanizing, offering excellent rust resistance suitable for exterior wall insulation, aquaculture enclosures, construction site protection, and fencing applications.
Electro-galvanized and electro-welded mesh with cold galvanizing
low cost, suitable only for short-term use in indoor dry environments; prone to rusting outdoors.
Modified/impregnated welded mesh or galvanized mesh with a plastic coating on the outer surface, featuring a smooth texture, rust resistance, and scratch resistance; commonly used for garden fences and aquaculture cages.
Core specification parameters
| Wire diameter | 0.3 mm – 6 mm; fine wires are used for filtration, while thick wires serve as protective barriers, cages, or shelves. |
| Hole size | Commonly used square holes include 1×1 cm, 2×2 cm, 5×5 cm, and 10×10 cm; rectangular holes can also be customized. |
| Product formats | Rolled mesh (long roll, suitable for large-area installation) and sheet mesh (pre-cut panels, ideal for further processing) |
| Production process | Straightening and cutting of metal wires, ensuring uniform arrangement of warp and weft wires; CNC resistance spot welding with complete fusion at intersection points, eliminating looseness or wire detachment; Post-processing: leveling, cutting into pieces, galvanizing, plastic coating, and polishing; Advanced processing: bending, rounding, edge sealing, welding handles and flanges, assembly of mesh baskets, cages, and protective covers. |
Key Product Advantages

FAQ
Frequently Asked Questions (FAQ)
Wire diameter ranges from 0.3 mm to 6 mm; fine wires are used for filter screens, while coarse wires are employed for aquaculture cages and protective fences. Standard square mesh sizes include 1×1 cm, 2×2 cm, 5×5 cm, and 10×10 cm, with customizable rectangular irregular mesh patterns available upon request.
Rolled mesh comes as one long roll and is cut to length on site, which suits large continuous areas — fencing, wall insulation, enclosures — and costs less per square metre. Sheet mesh is supplied as pre-cut flat panels, so it stays flat and square, which is what further processing needs: cutting to shape, bending, welding into baskets, cages and covers. Choose roll for area coverage and sheet for fabrication.
Yes, but wire diameter matters more. For a given wire, a smaller opening puts more welded intersections under the same load and spreads it further, so the panel carries more and deflects less. Going to a larger opening without increasing the wire diameter lowers capacity sharply. For shelving, walkways and cages the two are specified together — opening for what must not pass through, wire diameter for the load.
