Welded Wire Mesh Buying Guide: Galvanized, PVC-Coated, and Stainless Mesh for Concrete, Fencing, and Industrial Use
Welded wire mesh — steel wires resistance-welded into a square or rectangular grid — reinforces concrete slabs, builds security fences, makes animal cages, and guards machinery. Specify the wrong wire gauge, aperture, or coating and the panel rusts through, bows under concrete cover, or won’t meet the mesh ratio your engineer calculated.
This guide covers panels vs rolls, coatings, the dimensions that matter, standards, and a ready-to-send RFQ checklist.
Panels vs Rolls
| Form | Size | Best For |
|---|---|---|
| Welded panels | 2×1, 2.4×1.2, 3×2 m | Concrete, fencing, rigid uses |
| Rolls | 25–30 m long, 0.5–2 m wide | Long runs, cages, plaster |
| Cut sheets | To drawing | Machine parts, guards |
Wire Gauge, Aperture, and Panel Size
- Wire diameter: 1.0–6.0 mm; reinforcement typically 4–8 mm (BRC fabric).
- Aperture: 12.7 mm (1/2″) to 200 mm; concrete commonly 100–200 mm.
- Standard fabrics: A142, A193, A252, A393 (area mm²/m) — state the fabric reference instead of recalculating.
Coatings Compared
| Coating | Protection | Use |
|---|---|---|
| Bright (uncoated) | None | Embedded concrete only |
| Electro-galvanized | Light | Indoor, cages, shelving |
| Hot-dip galvanized | Heavy | Outdoor fencing |
| PVC-coated | Best + color | Garden, pools, coastal |
| Stainless 304/316 | Excellent | Food, marine, chemical |
Welded Mesh vs Woven, Chain-Link, Expanded
| Type | Rigidity | Use |
|---|---|---|
| Welded | Rigid, flat | Concrete, panels, fences |
| Woven | Flexible | Filtration, screens |
| Chain-link | Flexible roll | Perimeter fencing |
| Expanded | Rigid, no welds | Walkways, guards |

FAQ
Which fabric for a house slab? A193 (100×100×7 mm) is the common default; A142 suits light paths.
Electro or hot-dip for outdoor fence? Hot-dip — electro zinc chalks off within a few seasons outside.
Panels or rolls? Panels for concrete and rigid fencing; rolls for long flexible runs and cages.
