Galvanized Coils & Sheets
Hot-dip galvanized steel carries a zinc coating that protects the base metal from corrosion — essential in the Gulf climate and in coastal African markets. We supply GI coils, plain sheets and corrugated roofing profiles across a full range of coating masses.

FAQ
Common questions.
Which zinc coating should I choose?
Z80 – Z120 is common for indoor and ducting use; Z180 – Z275 is recommended for roofing, coastal and outdoor exposure in the GCC and Africa.
What is spangle?
The crystal pattern of the zinc. Regular spangle is standard; zero or minimised spangle gives a smoother surface for painting.
Can you supply corrugated roofing sheets?
Yes — GI and PPGI corrugated and trapezoidal profiles in standard lengths, subject to profile availability at the mill.
