| Property | Parameter | Description |
|---|---|---|
| Product Name | Weathering Steel Plates for Construction | High-strength low-alloy steel plates with enhanced atmospheric corrosion resistance |
| Material Grade | ASTM A588 Gr.A/B/C/K; Corten A; Corten B; S355J2W; Q355NH; SPA-H | International equivalent grades for structural weathering steel applications |
| Standard Compliance | ASTM A588 / A606; EN 10025-5; JIS G3125; GB/T 4171 | Meets major international standards for atmospheric corrosion-resistant structural steel |
| Chemical Composition – C | ≤ 0.19% | Low carbon content ensures good weldability and toughness |
| Chemical Composition – Mn | 0.80% – 1.25% | Manganese improves strength and hardenability |
| Chemical Composition – Si | 0.30% – 0.65% | Silicon contributes to corrosion resistance and deoxidation |
| Chemical Composition – Cr | 0.40% – 0.65% | Chromium is a key element forming the protective patina layer |
| Chemical Composition – Cu | 0.25% – 0.40% | Copper significantly enhances atmospheric corrosion resistance |
| Chemical Composition – P / S | P ≤ 0.035%; S ≤ 0.030% | Controlled phosphorus and sulfur levels for improved ductility and weld quality |
| Tensile Strength | 485 – 620 MPa (ASTM A588); 470 – 630 MPa (EN 10025-5 S355J2W) | High tensile strength suitable for load-bearing structural construction |
| Yield Strength | ≥ 345 MPa (ASTM A588); ≥ 355 MPa (S355J2W) | Minimum yield strength ensuring structural integrity under design loads |
| Elongation | ≥ 18% (in 200 mm gauge length) | Adequate ductility for forming, bending, and structural fabrication |
| Thickness Range | 3 mm – 150 mm | Wide thickness range covering thin plates to heavy structural plates |
| Width × Length | Width: 1000 – 4200 mm; Length: 3000 – 18000 mm | Custom cutting available; standard mill plates and coils supplied |
| Surface Finish | Hot-rolled; Sandblasted (Sa2.5); Natural Rusted Patina | Surface can be supplied as-rolled, pre-weathered, or blast-cleaned per project requirement |
| Application | Bridges, building facades, retaining walls, highway structures, sculptures, industrial architecture | Ideal for exposed structural elements where maintenance-free corrosion protection is required |
| Certification | Mill Test Certificate (EN 10204 3.1 / 3.2); CE Marking; ISO 9001:2015 | Full traceability documentation and third-party inspection available upon request |
| Packaging | Bundled with steel strips; wooden pallet or bare bundle; waterproof paper wrapping optional | Packed to prevent transit damage; export seaworthy packaging available |
| MOQ | 5 Metric Tons per grade/size | Mixed grades and sizes accepted to meet minimum order requirement |
Initial documentation gap — resolved satisfactorily before shipment
Ordered 12 tonnes of A588 Grade A plates at 16 mm for an industrial structure in Abu Dhabi. When the pre-shipment documentation pack arrived, the third-party inspection certificate referenced the wrong heat number — a clerical error. We flagged this immediately and, to their credit, the team corrected and reissued the full documentation set within 36 hours, prior to shipment departure. Material quality itself was fine — tensile and yield values on the MTR were within ASTM A588 limits. The issue caused a brief delay in our client's approval process but was fully resolved. Supplier responsiveness in fixing the error was good.
