Customers commissioning Four Square for the fabrication of mild steel often choose galvanising as the option for the corrosion prevention finish. Galvanising is generally the least expensive process to protect mild steel but does not have the same visual appeal as powder coating and is therefore ideal for non-public areas.

There are two types of galvanising: hot dip and cold dip. Each has their advantages and Four Square will assist with advice and cost estimates should you need assistance. In each case a protective coating of zinc covers the steel and prevents corrosive substances from reaching the underlying metal. Zinc serves as the sacrificial surface so even when scratched, the exposed steel will still be protected by the remaining zinc.
