Acceptable Quality with Minor Issues Resolved
Decent product quality overall, with one issue that was resolved professionally. We noticed some minor surface scratches on approximately 8% of our 10-ton order (1.0mm thickness, 1219mm width). The scratches were superficial at 0.02mm depth but not ideal for our visible appliance panel application where cosmetic appearance is critical. To their credit, the supplier's quality manager responded within 18 hours, reviewed photographic evidence, and offered a 6% discount on our next order plus confirmed implementation of additional protective film between wraps for future shipments. They also provided technical guidance on buffing techniques to minimize the visual impact. Overall acceptable for industrial applications. For aesthetic-critical uses, suggest requesting enhanced surface protection and pre-shipment inspection. Material properties and certifications were fully compliant with specifications.
