Quality is there — initial delivery delay was frustrating but resolved
Ordered 24 A572 Gr.50 enclosure frames for an industrial shelter project in Ohio, targeting a 21-day lead time. Actual delivery came at 29 days due to a production scheduling issue — this caused us a minor site delay. When I raised it, the team acknowledged the error, provided updated tracking daily, and issued a partial freight credit. The frames themselves met all specs: M24 bolt patterns aligned, weld quality passed our AWS D1.1 inspection, and the 80-micron primer coat was uniform. If the logistics match the material quality, this supplier is a strong long-term option.
