Acceptable Quality After Initial Documentation Delay
Ordered 15 tons of Q235B coils (5mm thickness, 1400mm width) for building framework project. Initial mill certificates were delayed by 5 days, causing some project scheduling concerns. However, the supplier expedited air freight delivery to compensate. Material quality was acceptable with tensile strength at 380 MPa. Thickness tolerance was within ±0.08mm specification. The supplier resolved the documentation issue professionally and offered discount on next order. Material performed adequately in our construction application.

Solid Quality with Competitive Mill Pricing
Purchased 20 tons of hot rolled coils (3.0mm thickness, 1500mm width) for resale to local manufacturers. Factory-direct pricing was 8% lower than regional distributors. Surface quality met commercial grade standards with minimal scaling. Delivery took 26 days, slightly longer than quoted 21 days due to port congestion. Packaging could be improved for tropical climate conditions. Material certificates were complete and accurate. Would order again for price-sensitive projects.
