Surface finishes
A guide to the finishes available at Gateshead Wrought Iron
Hot dip Galvanising
Hot dip galvanising is an industrial process where the steel fabrications are prepared and dipped into large tanks of molten zinc.
The molten zinc bonds to the steel forming a thick and durable protection against corrosion/rust.
Galvanising is recommended for most exterior projects, particularly those near the ocean.
It can be painted however it is to be noted that the surface is affected by the zinc with a rough & lumpy finish.
In some conditions the painted finish can suffer from a white patchy/powdery discolouration over time as the zinc ages. It may take over a year for this to appear. In most cases it is easily fixed with a minor touch up paint.
Powder coating
Powder coating is an economic finish suitable for internal & external projects out of the weather.
It produces a thicker coating improving wear resistance when compared to conventional wet paint making it perfect for handrails.
It is generally specified to match a range of contemporary colorbond colurs. More exotic colours & finishes including hammered, metallic and even textured are available however these may incur additional cost over standard colours.
Powder coating is not recommended for use with Hot Dip Galvanising
Spray Painting
Single pack spray painting is a cost effective wet painting option, generally done in our workshop. It’s an ideal option for wrought iron as its thinner and more matte finish provides a more classic look over powdercoating.
