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.

FAQ
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).
