Coated Coils & Sheets
Protection, layered in.
Zinc gives sacrificial protection. Aluminium adds a barrier that weathers for decades. Paint adds colour and another line of defence. We supply all three — GI, Al-Zn (galvalume) and pre-painted — as coils, slit coils or cut sheets.

Why it matters
Engineered for the site, not the brochure.
Al-Zn barrier
55% Al – 43.4% Zn – 1.6% Si coating delivers multiples of the life of plain galvanising.
Formable
Grades from commercial quality to high-strength for roll-forming and deep profiles.
Paintable finish
Passivated, oiled or acrylic-coated surfaces to suit your downstream process.
Cut to need
Full coils, slit coils or sheets cut to length.

Questions
Asked often
Galvanised or Al-Zn — which should I use?
For outdoor roofing and solar structures, Al-Zn typically lasts significantly longer at a similar coating mass. GI is preferred where the sacrificial behaviour of zinc at cut edges matters most, or for lower-cost indoor use.
Can you slit coils?
Yes. Coils can be slit to width or cut to sheet length for your line.
