Initial color batch variance — resolved satisfactorily by the team
First order was 8 tons of 1100-H14, 0.4 mm, polyester coating in a custom RAL 1013. On arrival, our QC team identified a visible color shift between two coils that exceeded our delta-E tolerance of 1.0. We raised the issue immediately. The supplier's technical team responded within 24 hours, acknowledged the variance from their colorimetry records, and arranged a replacement production run at no additional cost, delivered within 15 days. The replacement coils were within delta-E 0.6 across all units. Issue was handled professionally. We have since placed a follow-up order and results were clean. Marking 3 stars for the initial problem, but confidence has been restored.
