Q355B high frequency welded H‑beam HF welded H section steel
Q355B high frequency welded H-beam is an efficient and economic profile with a reasonable cross-section shape that offers higher section moment and load-bearing capacity than hot-rolled steel of the same weight. It allows for customizable processing, punching, branch cutting, and galvanizing. The welding process does not alter the base metal properties, making it ideal for special project specifications.
