Initial documentation gap resolved — product quality is acceptable
Ordered 0.40 mm PPGL corrugated panels with PVDF finish for a light industrial facility in Dubai. On first shipment, the SGS inspection report referenced AZ100 coating weight but our PO specified AZ150 per ASTM A792 — a discrepancy that caused a brief hold at customs. The supplier acknowledged the error quickly and provided corrected certification within 48 hours, which resolved the issue. Product itself — 840 mm cover width, 25 mm wave height — installed without problems and the PVDF finish looks good in the Gulf heat. Supplier has since confirmed improved documentation checks. Would consider reordering with clearer spec confirmation upfront.
