| Property | Parameter | Description |
|---|---|---|
| Product Name | Galvanized Steel | Hot-dip or electro-galvanized steel products for construction applications |
| Material Grade | DX51D / S250GD / S350GD | Equivalent to ASTM A653 CS Type B / SS Grade 33/50; JIS G3302 SGCC/SGCH |
| Standard Compliance | ASTM A653 / EN 10346 / JIS G3302 / GB/T 2518 | Meets international construction-grade galvanized steel standards |
| Chemical Composition (C) | ≤ 0.12% | Low carbon content ensures formability and weldability |
| Chemical Composition (Mn) | ≤ 0.60% | Manganese for improved strength and hardenability |
| Chemical Composition (P) | ≤ 0.10% | Controlled phosphorus for structural integrity |
| Chemical Composition (S) | ≤ 0.045% | Low sulfur to minimize brittleness |
| Tensile Strength | 270–550 MPa | Per ASTM A653 / EN 10346; varies by grade (e.g., S350GD: ≥ 420 MPa) |
| Yield Strength | 140–350 MPa | Minimum yield per grade; S250GD: ≥ 250 MPa; S350GD: ≥ 350 MPa |
| Elongation | ≥ 16–22% | A80 elongation per EN 10346; ensures ductility for construction forming |
| Zinc Coating Weight | Z60–Z275 (g/m²) | Both sides combined; Z275 = 275 g/m² per EN 10346 / ASTM A653 G90 |
| Thickness Range | 0.12–6.00 mm | Available in coils and sheets; custom thickness on request |
| Width Range | 600–1,500 mm | Standard slit coil and full-width sheet options available |
| Surface Finish | Regular Spangle / Minimized Spangle / Zero Spangle | Passivated, oiled, or chromate-free finish options for construction use |
| Application | Roofing, Cladding, Purlins, Framing, Decking | Widely used in residential, commercial, and industrial construction projects |
| Certification | ISO 9001 / CE Marking / Mill Test Certificate (MTC) | Third-party inspection available; SGS / BV / TÜV upon request |
| Packaging | Coil / Sheet / Slit Strip | Export seaworthy packaging; waterproof paper + steel strip bundling |
| MOQ | 25 MT per order | Full container load (FCL) preferred; LCL available for mixed orders |
Initial documentation gap — resolved professionally
Our first order was 40 tonnes of galvanized coil, Z120, 0.8 mm, for light commercial construction. The initial shipment arrived with MTC referencing EN 10204 2.2 rather than the 3.1 standard our project required. We flagged this immediately — the export team issued corrected 3.1 certificates within three business days and provided a written explanation for our records. Product quality itself was fine; zinc coating weight was within spec. Issue was handled without argument. We've since placed a follow-up order with clearer documentation requirements confirmed upfront.
