Initial Documentation Gap – Resolved Promptly by the Team
We ordered 40 MT of 0.45mm PPGL AZ70 with PE topcoat for a school refurbishment project requiring full EN 10169 third-party certification. On arrival, the inspection report referenced an older standard revision that our client's engineer flagged as non-compliant. This caused a two-week delay while updated documentation was issued. To their credit, the supplier acted quickly once we raised the issue — the correct certificates arrived within three business days and the project proceeded without further problems. Coating quality itself was fine; yield strength and corrosion resistance met spec. I would use them again but will confirm documentation requirements in writing upfront.
