What is AZ120 Galvalume Prime?
AZ120 Galvalume Prime is a top-tier coated steel product featuring a 55% aluminum-43.4% zinc-1.6% silicon alloy coating with a nominal weight of 120 g/m² total both sides. The "Prime" designation signifies first-quality material — free from defects, with uniform coating, excellent surface finish, and full mechanical property compliance.
Available in both flat sheet and coil formats, this product delivers superior corrosion protection and formability for high-performance applications across construction, manufacturing, and industrial sectors.
Product Highlights
Enhanced Coating Protection The AZ120 coating weight provides 20% more corrosion resistance than standard AZ100, making it ideal for moderate-to-harsh environments including coastal and industrial atmospheres.
Prime Quality Guarantee Every sheet and coil is inspected to prime standards — no slivers, edge waves, coating voids, or mechanical defects. Mill Test Certificates verify all specifications.
Dual Format Flexibility Order as master coil for continuous processing operations, or as precision-cut flat sheets ready for fabrication. Custom dimensions and slitting available.
Superior Heat Resistance Withstands continuous operating temperatures up to 315°C (600°F) without coating degradation — outperforming organic coatings and standard galvanized products.
Self-Healing Edge Protection The zinc-rich phase provides sacrificial corrosion protection at sheared edges, punch holes, and scratches, extending service life in installed applications.

FAQ
Q: What is "Prime" grade?
A: Prime is first-quality steel with no defects, full spec compliance, and complete certification. It differs from secondary or off-prime material which may have cosmetic or dimensional variances.
Q: Sheet vs. Coil — which should I order?
A: Order coil if you operate roll-forming or continuous processing equipment. Order flat sheets if you fabricate discrete parts or lack uncoiling/slitting capabilities. We can convert coil to sheet for you.
Q: Can AZ120 Prime be welded?
A: Yes, but welding parameters differ from mild steel or pure galvanized. Use lower heat input, appropriate filler rods, and ensure proper ventilation. Our technical team can provide welding guidelines.
Q: Is AZ120 suitable for coastal areas?
A: AZ120 performs well in moderate coastal environments. For direct salt spray exposure or tropical marine conditions, consider AZ150 or our specialized high-performance coatings.
Q: Do you offer color-coated AZ120 (PPGL)?
A: Yes. We supply pre-painted Galvalume in RAL and custom colors, using AZ120 as the premium substrate.
