GI Sheets

GI (galvanized) sheets use a zinc layer to protect steel against corrosion, making them a top choice for roofing, cladding, and outdoor fabrication.
- Coating Weights: Z120, Z180, Z200, Z275 (higher number = thicker zinc, better durability).
- Spangle: Regular, minimized, or zero-spangle to suit aesthetic and paintability needs.
- Profiles: Plain, trapezoidal/corrugated roofing, tile profile, decking.
- Paint Systems (PPGI): Polyester, SMP, PVDF topcoats over galvanized base for long-life color performance.
- Typical Thickness: 0.30–1.0 mm for roofing/cladding; heavier gauges for structural decking.
- Accessories: Ridge caps, flashing, fastening systems with sealing washers.
