Galvanised: Most chain wire mesh gates use a 2.5mm diameter standard weight hot-dip galvanised wire. For commercial fencing and gates, the mesh is available in a 3.15mm heavy galvanised wire. This is also used where climate conditions require a heavier duty, longer life wire, for example – near coastal areas.
PVC coated gates: This gate utilises a green or black coloured PVC coated mesh, to protect the galvanised wire and provide a higher end look and blend with the surrounding environment. The PVC coating is designed for prolonged life, as the coating provides extra protection over the galvanised wire and protects against rust and corrosion.
Stainless steel gates: Some chain wire fences are made of stainless steel. These are less common because of the cost but provide an extremely durable product.
