| Product Name | Agricultural Shed Color Steel Sheet | Pre-painted galvanized/galvalume steel sheet for agricultural building roofing and cladding |
| Material Grade | DX51D+Z / DX53D+AZ / SGCC / G550 | International equivalents: ASTM A755M, EN 10169, JIS G3312, GB/T 12754 |
| Standard Compliance | ASTM A755M / EN 10169 / JIS G3312 / GB/T 12754 | Meets international standards for prepainted metallic coated steel flat products |
| Chemical Composition (Base Steel) | C ≤ 0.12%, Mn ≤ 0.60%, P ≤ 0.045%, S ≤ 0.045%, Si ≤ 0.50% | Low-carbon steel substrate ensuring good formability and weldability |
| Coating Type | Galvanized (Z) / Galvalume (AZ55%Al-Zn) | Hot-dip zinc or aluminum-zinc alloy coating for enhanced corrosion resistance |
| Coating Weight | Z60–Z275 g/m² / AZ50–AZ150 g/m² | Coating mass per unit area per EN 10346 / ASTM A653; heavier coating for harsher agricultural environments |
| Paint System | Top coat: PVDF / SMP / PE (15–25 μm); Primer: 5–8 μm; Back coat: 5–15 μm | PVDF offers superior UV and weather resistance; PE suitable for standard agricultural use |
| Tensile Strength | 270–550 MPa | Per ASTM A755M / EN 10169; higher grades (G550) for structural roofing applications |
| Yield Strength | 220–500 MPa | Minimum yield strength ensuring structural integrity under wind and snow loads |
| Elongation | ≥ 14–22% (A80mm) | Per EN 10169 / GB/T 12754; ensures formability during roll forming and profiling |
| Thickness Range | 0.30–1.20 mm | Common agricultural shed thickness: 0.40–0.80 mm; custom thickness available on request |
| Width Range | 600–1,250 mm | Effective coverage width after profiling: 750–1,000 mm; slit coil widths customizable |
| Length / Coil Weight | Sheets: 1,000–12,000 mm; Coils: 3–10 MT | Cut-to-length sheets or coils supplied; standard coil inner diameter 508/610 mm |
| Surface Finish | Smooth / Embossed / Matte / High Gloss | RAL color matching available; standard colors: red, blue, green, grey for agricultural sheds |
| Application | Poultry houses, livestock barns, grain storage, greenhouse roofing, farm equipment sheds | Suitable for roofing, wall cladding, and ridge cap in agricultural and rural construction |
| Certification | ISO 9001:2015, CE Marking, SGS, BV | Third-party inspection and mill test certificates (MTC) available per EN 10204 3.1 |
| Packaging | Coils: waterproof paper + steel strip strapping; Sheets: wooden pallet + steel banding | Export seaworthy packaging; moisture-proof inner wrapping to prevent transit damage |
| MOQ | 5 MT per color/specification | Mixed container orders accepted; standard 20' FCL ≈ 20–25 MT depending on thickness |
Initial Color Mismatch Resolved Promptly by Supplier
Ordered 4,000 m² of 0.45 mm corrugated panels in RAL 6029. When the shipment arrived, approximately 800 m² of panels appeared slightly off-shade compared to the approved sample—likely a batch color-mixing variance. I raised the issue immediately; the supplier's QC team responded within 12 hours, acknowledged the deviation, and arranged a replacement batch shipped within 15 days at no additional cost. The replacement matched perfectly. The resolution process was professional and fair. I'm rating 3 stars for the initial issue but would consider ordering again given how efficiently it was handled.
