Acceptable Quality with Delivery Delay Resolved
Purchased 7 tons of Grade A plates (12mm thickness) for inland vessel repair work. Material quality was acceptable with ASTM A131 compliance confirmed by mill certificates. Yield strength at 265 MPa met minimum requirements. Initial delivery was delayed by 8 days due to logistics issues, but supplier arranged expedited shipping at no extra cost. One certificate had unclear stamp requiring re-issuance. Plates required additional surface cleaning before welding. Price was fair for the Great Lakes market. Issue resolution was professional and timely.
