IBR ZINCAL / ZINCALUME Roof Sheeting
IBR & CORRUGATED ZINCAL / ZINCALUME Roof Sheeting Cape Town, West Coast & Boland
ZINCAL® coated steel provides a superior alternative to galvanized steel. The technique of coating steel with Aluminium and Zinc (55% Aluminium, 43.5% Zinc and 1.5% Silicon) has been extensively researched and surpasses the performance of traditional galvanized steel.
The coating on ZINCAL® protects the base in two ways:
• The Aluminium coating component provides a tough physical barrier.
• The zinc in the coating provides sacrificial protection and also protects the steel at the cut edges.
The superior corrosive property increases the life of the steel core up to four times longer than that of galvanised steel.
