Acceptable Checkered Coil Quality with Delivery Delay Resolved
Ordered 6 tons of checkered coil in 4.0mm thickness, 1219mm width for factory walkway panels in Ontario. Material quality itself was fine — tensile properties on the MTC were within spec and the anti-slip pattern was consistent. However, delivery ran 5 days longer than the quoted 7–10 business days due to a port congestion issue, which caused a minor delay on our installation schedule. To their credit, the supplier proactively communicated the delay and provided daily shipping updates until the goods cleared customs. The material passed our incoming inspection without issues. Would consider ordering again but will build in extra buffer time for future projects.
