| Property | Parameter | Description |
|---|---|---|
| Product Name | Corrosion Resistant Color Coating Steel | Pre-painted galvanized/galvalume steel with enhanced anti-corrosion coating |
| Material Grade | DX51D, DX52D, DX53D / SGCC, SGCD | Equivalent to ASTM A755, EN 10169, JIS G3312 substrate grades |
| Standard Compliance | ASTM A755 / EN 10169 / JIS G3312 / GB/T 12754 | Meets international pre-painted steel coil standards for corrosion resistance |
| Chemical Composition (Substrate) | C ≤ 0.12%, Mn ≤ 0.60%, P ≤ 0.045%, S ≤ 0.045%, Si ≤ 0.50% | Low-carbon steel base ensuring formability and coating adhesion |
| Coating Type | Polyester (PE), PVDF, SMP, HDP, Epoxy | Top coat options selected based on corrosion environment and UV resistance requirement |
| Coating Thickness | Top coat: 15–25 µm; Primer: 5–7 µm; Back coat: 5–12 µm | Measured per ASTM D1400 / EN ISO 2808; total DFT varies by specification |
| Zinc/Aluminum Coating Mass | Z60–Z275 g/m² (Galvanized); AZ50–AZ150 g/m² (Galvalume) | Per ASTM A653 / A792; heavier coating improves base metal corrosion protection |
| Tensile Strength | 270–500 MPa | Per EN 10169 / ASTM A755; varies by substrate grade and temper |
| Yield Strength | 140–420 MPa | Minimum yield strength per applicable substrate standard |
| Elongation | ≥ 16–30% (A80mm) | Ensures formability during roll forming, bending, and profiling operations |
| Thickness Range | 0.14 mm – 1.50 mm | Substrate thickness; total thickness includes coating layers |
| Width Range | 600 mm – 1,500 mm | Slit coil or full-width coil available per customer requirement |
| Corrosion Resistance | Salt Spray Test ≥ 500–2000 hours | Per ASTM B117 / ISO 9227; PVDF and HDP coatings achieve superior performance |
| Surface Finish | Smooth, Embossed, Matte, High Gloss | RAL / custom color matching available; gloss level 10–85 GU per ASTM D523 |
| Application | Roofing, wall cladding, home appliances, automotive parts, HVAC ducts | Suitable for industrial, commercial, and residential construction environments |
| Certification | ISO 9001, SGS, BV, CE, RoHS | Third-party inspection and material test reports (MTR) available upon request |
| Packaging | Eye-to-sky or eye-to-wall coil; waterproof paper + steel strip strapping | Export seaworthy packaging; coil weight typically 3–8 MT per coil |
| MOQ | 25 MT per order | Mixed grades and colors accepted; sample coils available for qualification testing |
Initial Color Variance Issue — Resolved Satisfactorily After Follow-Up
Our first order of 10 tonnes of 0.38 mm PE-coated PPGI in RAL 6005 for transportation equipment panels showed a slight color deviation between two coil batches — visually noticeable when panels were placed side by side. We raised the issue with the technical team, who confirmed a batch mixing variance and arranged replacement coils at no additional charge within 14 days. Replacement material matched perfectly and met ASTM A755 coating adhesion requirements. The resolution process was handled professionally. Docking one star for the initial quality control lapse, but the supplier's responsiveness has rebuilt our confidence for future orders.
