Galvanized flat sheet has four actual width-range labels spanning900–2000mm. The3mm/4mm title request differs from the0.21–0.50mm family thickness and needs confirmation.

Select dimensions and material

DX53D body grade and Q235 title requirement need one actual composition. Confirm exact thickness, width and1200–2500mm reference length using a blank drawing.

• Flat Steel Plate shape.
• Mid Hard condition label.
• Non-oiled description.
• Skin pass reference.
• Cutting and bending services.

Verify coating and mechanics

Z181–Z275 and Z10–Z275 are coating designations needing actual basis. Tensile270–550MPa and yield140–420MPa require selected-grade/condition tests.

Agree facade acceptance

Request ASTM A123 applicability and actual surface records. Corrosion-resistant/facade context does not establish corrosion life, panel approval or structural capacity without actual material and configuration evidence.
