Initial surface marking issue — fully resolved by supplier
Our first 30 MT order of 0.4 mm PE-coated PPGI, Z120, RAL 3009 arrived with minor roll-pressure marks on roughly 5% of coil surface area — visible under direct light. We raised a formal claim with photos. The supplier's QC team responded within 48 hours, acknowledged the issue, and arranged replacement coils at no additional freight cost within 15 days. Replacement material was defect-free and EN 10169 cert matched specs. Appreciate the professional after-sales handling; willing to trial a second order based on that response.
