Hot-coating Al-Zn-Si steel plate (coil) combines the advantages of galvanized and aluminum steel plate (coil) : its corrosion resistance is 2-6 times as much as galvanized plate in various atmospheric environments; it does keep the same color at the temperature 315C and could be used for a long time at the temperature 500-600C for its good heat- resistant, anti-oxidation and heat-reflected performance.Specifications: 1)Thickness of the galvanized steel coil: 0.3mm-3.0mm 2)Thickness tolerance of Galvanized Steel Coil: +/-0.03mm 3)Width of the galvanized steel coil: 50mm-1250mm 4)Width tolerance: +/-0.15mm 5)Zinc coating: 60gsm-275gsm 6)Surface treatment: Chromated, unoiled/oiled, minimum or regular spangle 7)Quality of the galvanized steel coil: Commercial quality (soft and hard), lock ormingquality,drawing quality, structural quality as per JIS G 3302, 8) Surface finish: Regular spangle, minimized spangle, zero spangle, galvannealed 9) Surface treatment: Chromated, non-treated (dry), organic 10) Oiling: Unoiled or oiled
