Galvanised vs PVC-Coated Wire Mesh
Quick answer
Galvanised mesh is protected by a metallic zinc layer that sacrificially guards the steel, giving a bright industrial finish ideal for structural use. PVC-coated mesh adds a plastic outer layer over wire (often pre-galvanised) for a softer touch, colour and extra weathering, suiting decorative, garden and contact-sensitive jobs.

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.

Figure summary: Galvanised mesh is protected by a zinc layer for good, economical corrosion resistance, while PVC-coated mesh adds a plastic over-layer that gives a double barrier, a coloured finish and longer life in wet or harsh conditions. Pick galvanised for cost, PVC-coated for durability and appearance.
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.
Rule of thumb
Need tough and economical? Galvanised. Need colour, softness or a tidy look (often over a galvanised core)? PVC-coated.
Frequently asked questions
Does PVC-coated mesh last longer than galvanised?
It can, because the plastic layer seals the wire from moisture and is frequently applied over an already galvanised core. The main caveat is that if the PVC coating is cracked or chipped, moisture can reach the wire underneath, so handling and installation matter for long service life.
How does galvanising protect the wire?
Galvanising adds a zinc layer that works as both a physical barrier and a sacrificial anode. Because zinc corrodes in preference to steel, it continues to protect the wire even where the coating is scratched, which is a key advantage of metallic zinc protection.
Is PVC-coated mesh safer to handle?
Generally yes. The plastic layer gives a smoother, softer surface and tends to reduce sharp edges, which is part of why it is popular for garden, pet and contact-sensitive applications. It is not a substitute for care when cutting, where fresh edges can still be sharp.
Which is cheaper, galvanised or PVC-coated?
For an equivalent mesh, galvanised is typically lower in cost because PVC adds an extra coating step. The PVC premium often pays back through better appearance, a softer finish and added weather protection rather than raw durability alone.
Can mesh be both galvanised and PVC-coated?
Yes, and it commonly is. Applying PVC over a galvanised core combines a sealed plastic outer barrier with the sacrificial zinc protection beneath, giving layered defence against corrosion.
