Color variance issue in first batch — replacement handled professionally
Initial order of 6 tons of 3003-H24 polyester-coated sheets at 1.0 mm in a custom RAL 5015 color showed a visible gloss variance between two coils when installed side by side on a commercial facade. Raised the issue with the support team and provided photographic documentation. They acknowledged the batch inconsistency, arranged a replacement shipment within 15 days at no additional cost, and provided updated QC reports confirming gloss uniformity at 45 GU across the replacement coils. The resolution process was handled professionally. Upgraded confidence in their after-sales process as a result.
