Which is better, PVC coated wire mesh or galvanized wire mesh?

People often ask whether PVC-coated or galvanized steel wire mesh fencing is better. Actually, both types have their advantages and cannot be simply dismissed. Sometimes, galvanized fencing is first PVC-coated and then coated, combining the strengths of both for a more perfect result.

PVC-coated wire mesh fencing, also known as plastic-coated or powder-coated fencing, involves applying a layer of plastic to the surface of the fencing to isolate it from the external environment, preventing oxidation and corrosion, thus extending its lifespan. The thickness of the PVC coating is generally between 0.2-0.6 mm, while powder coating is typically 0.2-0.3 mm thick, and PVC coating is generally around 0.5 mm thick. Besides corrosion protection, another significant advantage of PVC-coated fencing is its enhanced aesthetic appeal.

Galvanized fencing comes in two types: hot-dip galvanizing and cold-dip galvanizing. Similar to plastic coating, galvanizing aims to prevent corrosion. Hot-dip galvanized fencing offers corrosion protection that is just as effective as, and even surpasses, plastic-coated fencing. However, its color options are somewhat limited compared to galvanized fencing, lacking the vibrant hues of red, yellow, black, and green, resulting in a less flashy but more substantial look.

Galvanizing is often combined with plastic coating, essentially applying a plastic coating to the surface of the galvanized fencing. This enhances the fencing's corrosion resistance, significantly extending its lifespan, while also meeting aesthetic requirements and adding visual appeal. This method is particularly common in national engineering projects and major initiatives to produce galvanized-plastic-coated fencing. Galvanized fencing is frequently found in frame fencing or expanded metal fencing.
