Initial color inconsistency resolved satisfactorily
Our first order of 25 tonnes of 0.6 mm panel in RAL 3009 oxide red showed a slight gloss variation between two coils — measured at 38 GU versus our specified 45 GU at 60°. We flagged this immediately. The supplier's QC team acknowledged the oven temperature deviation in one batch and air-freighted replacement coils within 10 days at no extra cost. Subsequent coils matched spec perfectly. The swift resolution and honest communication restored our confidence. We have since placed a follow-up order of 40 tonnes. Issue was a one-time occurrence, not a systemic problem.
