GI roofing sheets are made from galvanized iron and are mainly valued for strength, practicality, and cost-effectiveness.

Colour coated roofing sheets include an additional painted protective layer, which improves appearance and weather resistance.

Compared to plain GI sheets, colour coated sheets usually provide better protection against moisture, rust, and surface wear.

GI sheets are often used where functional performance matters most, while colour coated sheets are preferred for both performance and aesthetics.

The right choice depends on project budget, environment, expected life, and desired finish.
