| Property | Parameter | Description |
|---|---|---|
| Product Name | Heat Insulated Color Steel Sheet | Pre-painted steel sheet with integrated thermal insulation core, used in building envelope systems |
| Material Grade | Q235B / DX51D+Z / S280GD+Z | International equivalents: ASTM A653 CS Type B, EN 10346 DX51D, JIS G3302 SGCC |
| Standard Compliance | GB/T 12754, EN 10169, ASTM A755 | Meets GB 50176 thermal design code; insulation core per GB/T 10294 (EPS/PU/rock wool) |
| Chemical Composition | C ≤0.12%, Mn ≤0.60%, P ≤0.045%, S ≤0.045%, Si ≤0.50% | Base steel low-carbon composition ensuring good formability and coating adhesion |
| Tensile Strength | 270–560 MPa | Per EN 10346 / GB/T 12754; varies by steel grade (DX51D: ≥270 MPa, S280GD: ≥360 MPa) |
| Yield Strength | 220–420 MPa | S280GD+Z: ReH ≥280 MPa; DX51D+Z: ReH ≥140 MPa (EN 10346) |
| Elongation | ≥16–22% | A80 elongation per EN 10346; higher elongation grades suitable for deep roll-forming profiles |
| Insulation Core Material | EPS / PU Foam / Rock Wool / Glass Wool | PU density 38–42 kg/m³; Rock wool density 100–120 kg/m³; EPS density 15–20 kg/m³ |
| Thermal Conductivity | PU: 0.022–0.024 W/(m·K); Rock Wool: 0.036–0.040 W/(m·K) | Per GB/T 10294 / ISO 8301; lower value indicates better insulation performance |
| Panel Thickness | 50 mm / 75 mm / 100 mm / 150 mm / 200 mm | Total panel thickness including steel skins and insulation core; custom thickness available |
| Steel Skin Thickness | 0.3 mm – 0.8 mm | Top skin: 0.4–0.6 mm; bottom skin: 0.3–0.5 mm; zinc coating Z100–Z275 g/m² |
| Panel Width | Effective width: 900 mm / 1000 mm / 1150 mm | Overall width up to 1200 mm; effective coverage width depends on profile design |
| Panel Length | 2000 mm – 12000 mm (customizable) | Standard lengths 3–6 m; max single piece up to 12 m for wall/roof applications |
| Surface Finish | PVDF / PE / SMP coating; RAL color options | Top coat 20–25 μm (PE), 25–30 μm (PVDF); gloss level 30–70%; salt spray resistance ≥500 h |
| Application | Industrial buildings, cold storage, warehouses, prefab structures, clean rooms | Roof panels, wall cladding, partition walls; suitable for temperature-controlled environments |
| Certification | ISO 9001, CE Marking, FM Approval (fire-rated), SGS | Fire performance per EN 13501-1; thermal performance per EN ISO 6946 |
| Packaging | Steel strip bundled, PE film wrapped, wooden pallet | Panels stacked with protective foam interleaving; export seaworthy packaging available |
| MOQ | 500 m² per order | Mixed specifications acceptable; OEM/custom color and profile available above MOQ |
Initial documentation gap — resolved professionally, product quality acceptable
Ordered 3,200 m² of 75 mm PU core panels for a commercial cold room project in Queensland. The panels themselves met spec — 0.4 mm substrate, λ = 0.022 W/(m·K) confirmed by our lab. However, the initial shipment was missing the third-party fire test certificate required by Australian Building Code. I raised this with the account manager and within 48 hours the full EN 13501-1 documentation was emailed and a hard copy dispatched via courier. Issue was handled professionally and didn't delay our project. Quality is good — I'd order again but would confirm documentation checklist upfront.
