Initial coating inconsistency on first batch — resolved promptly on reorder
Our first order of 2,200 linear meters of 350 MPa C-section girts (2.0mm, Z275 galvanized) included approximately 120 meters where the galvanizing coating measured below the specified 275 g/m² threshold on independent inspection. We raised this formally with the supplier. They acknowledged the issue, provided a corrected batch within 10 days at no additional cost, and updated their QC sign-off process. The replacement material passed all checks. Subsequent orders have been fully compliant. Responsiveness to the problem was handled professionally.
