Product Description
Engineered for welding-intensive applications, our 0.12-4.0mm Customizable Galvanized Steel Coil delivers superior weldability and corrosion resistance. Featuring a zinc-iron alloy layer (ZF) with optimized microstructural bonding (10μm min.), this coil achieves seamless welding without spatter or porosity. The hot-dip process applies 30-275g/m² zinc coating (adjustable per project needs), backed by 1,000+ hours ASTM B117 salt spray resistance for harsh industrial environments. Certified to EN 10142 and JIS G3302, it ensures structural integrity in fabrication-critical sectors like automotive frames and pre-engineered buildings.

Applications
- Structural Fabrication: Welded trusses, support beams, and crane girders requiring zero porosity joints (ISO 5817-B).
- Automotive Chassis: Laser-welded components with ≤0.1mm heat-affected zone (HAZ) distortion.
- Pre-Engineered Buildings: Bolt-free welded frames for warehouses, leveraging EN 1090-2 certification.
- Industrial Piping: Seamless ERW (Electric Resistance Welded) pipes in chemical plants.
Customization Options
- Material Grades: DX53D+Z (deep drawing), S350GD+Z (structural), S550GD+Z (high-strength).
- Zinc Coating: 30g/m² (indoor) to 275g/m² (coastal).
- Edge Processing: Mill edge/trimmed edge with PVC protectors for weld alignment.
- MOQ: 25 tons (standard), 5 tons for custom spangle/texture.
Packing and Shipping
Triple-Shield Packaging: VCI anti-rust kraft paper inner layer, 0.3mm PE waterproof film with moisture indicators, steel-strapped pallets + edge guards (max. 8-ton coils).
Global Logistics: FOB/CIF from Chinese ports; 15-day delivery for Asia, 30 days globally.
Frequently Asked Questions
Why choose this coil for welding over standard GI?
The ZF alloy layer (FeZn₇/FeZn₁₃) reduces zinc vaporization at 450°C, preventing weld cracks.
Optimal coating thickness for weld durability?
60-120g/m² balances corrosion resistance and low spatter (per AWS D1.3 guidelines).
Maintenance requirements?
Self-passivating zinc layer reduces need for repainting; biennial inspections suffice.
Certifications for structural welding?
Complies with EN ISO 1461 (galvanizing) and EN 1090-2 (CE welding).
