Initial color batch mismatch — resolved promptly, quality now confirmed
First order of 5 metric tons of 1100-H14 at 0.4 mm in RAL 3020 polyester coating. On arrival, one coil showed a visible color shift versus the approved sample — our spectrophotometer measured ΔE 1.8, outside the ΔE ≤ 1.0 spec. We raised the issue immediately; the supplier responded within 4 hours, arranged a replacement coil dispatched within 5 working days, and provided a corrective action report explaining a curing oven calibration drift. Replacement matched the spec at ΔE 0.6. Issue was handled professionally. We've since placed a second order and quality has been consistent.
