Launch SimulatorGalvanized vs Galvalume
Galvalume costs a little more up front, but its aluminium–zinc–silicon coating lasts longer and resists corrosion better. Here's how the two coatings compare.
| Feature | Galvanized Steel | Galvalume Steel |
|---|---|---|
| Coating | 100% Zinc | 55% Aluminium, 43.4% Zinc, 1.6% Silicon |
| Corrosion Resistance | Good | Superior |
| Edge Protection | Superior self-healing on cut edges | Good, slightly less edge-healing than pure zinc |
| Best Environment | Farms, high-ammonia, heavy cutting/bending | Standard roofs, commercial/residential builds |
Prefer a coloured finish? Prepainted sheets are available as PPGI (galvanized base) or PPGL (galvalume base) — PPGL pairs your chosen colour with Galvalume's superior corrosion resistance and longer life.
