Frequently Asked Questions
Q: What is the difference between Galvalume and Galvanized steel?
A: Galvalume has 55% Al-Zn coating, offering better corrosion resistance, while galvanized steel uses 100% zinc.
Q: Can Galvalume be painted?
A: Yes! It accepts pre-painted coatings (PPGI/PPGL) for enhanced durability and color options.
Q: What is the lifespan of Galvalume?
A: Typically 20-30 years, depending on environment and coating thickness.
Q: Is Galvalume weldable?
A: Yes, but requires proper techniques (zinc-aluminum fumes need ventilation).
