Initial color inconsistency flagged — supplier resolved it professionally
Ordered 45 tonnes of 0.8 mm polyester-coated cladding in RAL 9006 for a logistics center in Brisbane. On arrival, approximately 8% of panels in the first container showed a slight gloss variation compared to approved samples — noticeable under direct Queensland sunlight. We raised this immediately and the supplier responded within one business day, arranged independent color measurement per ASTM D2244, confirmed the variance, and replaced the affected panels within 12 days at no additional cost. The replacement batch was spot-on. The issue was frustrating initially, but the resolution was handled transparently and efficiently. Comfortable ordering again.
