Galvanized Steel |
|
|
| | | |  | | Hot dip galvanized steel sheet in commercial, structural and full hard quality is a product that combines the mechanical resistance of steel and corrosion resistance of zinc. It is used as raw material in the refrigeration, construction, automobile and general metal industry. | | | | | It comes in coils of up to 10 tons or in cut-to-length sheets in thicknesses ranging from 0.27 mm to 1.90 mm and widths ranging from 914 mm to 1220 mm.
ACESCO’s galvanized steel complies with specifications given in ASTM A653, ASTM A924 and NTC 4011* standards.
