Decent Product — Initial Coating Concern Was Resolved Professionally
Ordered 15 tons of 80×8mm galvanized flat bars for a building project in Abu Dhabi. Upon inspection, we found that about 10% of pieces in two bundles showed coating thickness below 45 µm in localized spots, which concerned us given our harsh coastal environment. Contacted the supplier and they responded within 24 hours with a resolution — provided replacement material shipped at their cost and adjusted the invoice. The replacement batch measured 60–75 µm consistently. Appreciate the professional handling, though initial QC should have caught this. Product is now performing well on site after three months of exposure.
