Minor Paperwork Issue Resolved Quickly
Ordered 10 tons of primer-coated A36 angle 3"×3"×5/16" for a bridge maintenance project. The steel itself was fine — proper yield strength, clean primer coating, accurate dimensions. However, the initial mill certificates had a discrepancy in the listed manganese content that didn't match the heat number. We flagged it and the supplier issued corrected documentation within 48 hours with full explanation. Slightly inconvenient as it delayed our project approval by a few days, but the response was professional and the underlying material quality was never in question.
