Our guide to preventing metal corrosion
Corrosion is the deterioration of metal caused by a chemical reaction of metal with its environment. Exposure to various climates can also lead to corrosion. All metals can corrode, especially if the metals in question are not protected.
But corrosion can be stopped or prevented, and there are many ways to do this.
We always recommend that exterior mild steelwork is hot dip galvanised prior to coating. Hot dip galvanising is the best possible way to prevent rusting in mild steel and is a silver grey colour so is usually coated with conventional paints or powder coating.
Powder coating has been shown in studies to inhibit corrosion more than liquid paint. Powder coating metal helps create a homogeneous, thoroughly-covered surface.
We offer a powder coated primer and topcoat which is usually used for non intricate exterior metalwork that doesn't require the corrosion resistance that hot dip galvanising offers.
Most of our powders are architectural spec which offers a better external corrosion resistance and are much tougher and durable than standard powder finishes.
