Innovative methods and production techniques are taking steel to new levels of strength, formability and versatility. In Zincal®, the durability and service life of modern coated steel is extended even further. Zincal® is produced by a unique, efficient process whereby rolled steel is continuously hot-dipped into a 55% Aluminium, 43.5% Zinc and 1.5% Silicon Alloy. This patented coating protects the steel in two ways:
The aluminium component of the coating provides a tough physical barrier between the extreme atmospheric conditions and the inner core of steel.
The zinc in the coating provides sacrificial protection and also protects the steel at the cut edges.
