Galvanised steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel. Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion.
For sheet gauges less than 2mm, New Zealand Steel produces galvanised steel on their metallic coating line. Galvanised hollow sections and pipe are also produced. Some mild steel products are hot dipped galvanised after fabrication.
