| Application | ACP panels, roofing, cladding, signage, interior decoration, automotive trim | Widely used in construction, transportation, and consumer electronics sectors |
| Certification | ISO 9001, SGS, CE, RoHS, REACH | Mill test certificate (MTC) per EN 10204 3.1 available upon request |
| Packaging | Eye-to-sky coils on wooden pallets; sheets interleaved with PE film | Waterproof kraft paper wrapping; export seaworthy packaging standard |
| MOQ | 5 MT per order (mixed alloys/colors acceptable) | Sample orders accepted; lead time 15–25 days for standard specifications |
Initial colour batch variance flagged — resolved promptly, quality now confirmed
Our first order of 5 tonnes of 3105-H24 at 0.80 mm in a custom sand-beige tone showed a visible gloss variance between two coils — one measured 38 GU, the other 29 GU against our approved 35 GU target. We raised this immediately. The supplier's quality team acknowledged the batch inconsistency within 24 hours, arranged replacement coils at no additional cost, and shipped within 8 days. The replacement batch measured 34–36 GU consistently. ASTM B117 salt spray data on the replacement was also provided. Issue was handled professionally. We have since placed a follow-up order and quality has been consistent.
