ZINCAL® is produced by a unique efficient process whereby rolled steel is continuously hot dipped into a patented alloy of 55% Aluminium, 43.5% Zinc and 1.5% Silicon.
This patened coating protecs the steel in two ways:
- The Aluminium componet 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.
A thin organic coatibg (TOC) is applied to ZINCAL®, a process that offers wide benfits like anti-fingerprints, elasticity, weldability and formability. TOC also contains dry lubricant additives that increase lubricity of the ZINCAL surface and wax or oil is not requird during the forming process.
