Galvalume Steel Coil, AZ121–Z150 and 55 Percent Aluminum Coating Requirements
Coated steel coil has four actual width bands covering 900–2000 mm and a separate specification label of 609–1250 mm. The technical zinc coating entry is 40–275 g/m².
Confirm the required coating chemistry and the mixed AZ121–Z150 designation. A requested 55 percent aluminum coating is not established by the accompanying galvanized product and zinc descriptions. Define the base grade, exact gauge and the dimensional meaning of the specification label.
The thickness entry 0.12–0.8 has no unit and differs from the requested 0.5–1.0 mm range. Cold rolling requirements need reconciliation with the hot rolled base description. No numerical hardness, wear resistance or coating life is supplied by full hard wording and generic standards references.
