| MOQ | 25 MT per order | Mixed colors and specifications accepted; customized orders negotiable |
Initial color deviation flagged — resolved promptly, quality now consistent
First order of 30 tonnes of 0.45 mm PPGI in a custom RAL color showed a slight hue deviation on two coils versus the approved sample — noticeable under our quality control lighting. We raised the issue immediately. The supplier responded within hours, accepted the non-conformance report, and arranged replacement coils at no additional cost within 12 days. Second delivery matched perfectly. ASTM A755 compliance and 20 µm topcoat thickness were correct throughout. Issue was resolved professionally; we are continuing the business relationship.
