ASTM A653 SGCC galvanized steel sheet in coil
ASTM A653 SGCC galvanized steel sheet in coil are produced by immersing steel in a zinc bath. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.
ASTM A653 SGCC galvanized steel sheet in coil are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 60 – 275 grams per square meter.
Thickness:0.17-1.2mm
Width:914-1250mm(900mm,1215mm,1250mm,1000mm the most common)
Zinc-coating: 30g/m2-280g/m2 Al-Zn Coating: 150g/m2-180g/m2
Surface Protection: PE, SMP, HDP, PVDF
ASTM A653 SGCC galvanized steel sheet in coil are manufactured to meet almost any customer ordered requirement with respect to corrosion resistance of the coating, strength level and/or formability requirements of the steel sheet, thickness, width, surface quality, and surface finish.
