GI sheets are zinc-coated steel sheets that provide basic corrosion protection and are widely known for affordability.

Colour coated sheets include an additional paint layer over the base metal, which improves both durability and appearance.

This extra coating helps the sheet perform better in demanding environments while also offering a cleaner and more modern finish.

For projects where appearance, longevity, and reduced maintenance matter, colour coated sheets are usually the better option.

In long-term roofing applications, colour coated sheets are generally considered the better choice compared to standard GI sheets.
