Z40–Z300G DX51D Hot Galvanized Steel Coil Zinc Plating on Iron for Container and Building Applications

１．Product Overview

Z40–Z300G DX51D hot galvanized steel coil is used for container plates, roofing sheets, building materials, home appliances, machinery parts, wall panels, garage doors, window blinds, and industrial fabrication.

The product is manufactured according to ASTM A653, JIS G3302, and EN10147 standards. Zinc coating from 40g/m² to 450g/m² provides corrosion protection for steel substrates used in construction, appliance, transportation, and industrial applications.

２．Technical Solution

The steel substrate is coated by hot dip galvanizing to form a zinc protective layer on the steel surface. This zinc layer supports corrosion resistance during outdoor exposure, storage, shipment, and downstream fabrication.

Surface treatment options include passivated, chromated, and oiled finish. These treatments help reduce oxidation risk during storage and improve handling performance during processing.

Spangle options include regular spangle, minimized spangle, big spangle, and zero spangle, allowing selection according to appearance, coating, and downstream painting requirements.

３．Specifications

６．Advantages

• 40–450g/m² zinc coating supports different corrosion resistance requirements.
• 0.15–3.8mm thickness range covers common building, appliance, and industrial applications.
• 508mm and 610mm coil IDs support standard decoiling and processing lines.
• Regular, minimized, big, and zero spangle options support different surface appearance requirements.
• Passivated and oiled surfaces improve storage and shipment protection.
• ASTM A653, JIS G3302, and EN10147 standards support international procurement and project use.

７．How to Choose

• Choose DX51D+Z for general forming, roofing, and building material applications.
• Choose TS350GD or TS550GD when higher strength is required.
• Choose higher zinc coating when stronger corrosion resistance is required.
• Choose zero spangle when smoother surface or painting is required.
• Choose regular or big spangle when visible galvanized appearance is acceptable.
• Choose oiled or passivated surface for improved storage and shipment protection.
• Confirm thickness, width, zinc coating, grade, spangle, surface treatment, coil ID, and packing method before production.
