Galvanising and PVC coating are two common ways to protect wire mesh from corrosion, and they often work together. The right pick depends on whether you prioritise rugged metallic protection or a softer, coloured finish that is kinder to hands, plants and animals.
What is galvanised wire mesh?
Galvanised mesh is coated with zinc, applied either before weaving or welding (pre-galvanised) or afterwards by hot-dipping. The zinc protects the underlying steel in two ways: it forms a barrier, and it corrodes preferentially to the steel, providing sacrificial protection even at small scratches. The result is a bright metallic-grey finish that is hard-wearing and well suited to fencing, cages and structural mesh where appearance is secondary to durability.
What is PVC-coated wire mesh?
PVC-coated mesh has a layer of polyvinyl chloride bonded over the wire, very often over a galvanised core for layered protection. The plastic skin seals the wire from moisture, adds colour (commonly green, black or anthracite) and gives a smoother, softer surface that is gentler to touch. This makes PVC-coated mesh popular for garden fencing, decorative screens, pet and aviary enclosures, and anywhere a less industrial look or reduced sharpness is wanted.
Side-by-side comparison
| Criteria | Galvanised mesh | PVC-coated mesh |
|---|---|---|
| Protection mechanism | Zinc barrier plus sacrificial protection of steel | Plastic barrier layer, often over galvanised wire |
| Appearance | Bright metallic grey, industrial | Coloured and smooth (green, black, anthracite, etc.) |
| Weathering | Durable; zinc weathers to a dull grey over time | Good, with the plastic shielding the metal; UV can age the coating |
| Touch / feel | Harder, metallic, can have sharper edges | Softer and smoother to handle |
| Typical use | Structural fencing, cages, reinforcement | Decorative, garden, pet and aviary, contact-sensitive uses |
| Cost | Typically lower for equivalent mesh | Usually higher due to the added coating step |
Which should you choose?
- Choose galvanised when you want rugged, cost-effective metallic protection for structural fencing, cages or reinforcement and appearance is not the priority.
- Choose PVC-coated when you want colour, a softer feel and a more finished look for gardens, decorative screens or animal enclosures.
- Remember the two are not mutually exclusive: PVC coating over a galvanised core combines a sealed plastic skin with underlying zinc protection.
Need tough and economical? Galvanised. Need colour, softness or a tidy look (often over a galvanised core)? PVC-coated.
