Initial color variance issue — resolved satisfactorily by supplier
Our first order of 3003-H16, 0.60 mm, polyester-coated sheet in a custom grey showed slight color deviation between two coils when measured with a spectrophotometer against our approved sample. Delta-E reading was 1.8, above our 1.2 tolerance. We flagged this immediately. The supplier's technical team responded within 24 hours, investigated the coating batch records, and arranged replacement coils at no additional cost within 12 days. The replacement material was spot-on. The issue was handled professionally, and we have since placed a follow-up order. Supplier accountability recovered our confidence.
