elding H-shaped steel, because of the use of welding technology to produce section for H-shaped, named, divided into submerged arc welding H-shaped steel, high frequency welding H-shaped steel. The process of submerged arc welding H-beam: steel plate - Automatic slitting - assembly - automatic submerged arc welding - flaw detection - flange correction - Web correction - end processing - sand blasting and derusting - painting. The automatic submerged arc welding production line is controlled by microcomputer, which ensures the dimensional accuracy of H-beam and the weld quality meets the national standard.

It can be processed, designed and combined with any project, and can manufacture special specifications to meet the actual needs of special projects.

The specification of H-beam is designed economically. Its section moment, section coefficient, pressure resistance and load bearing capacity are much higher than those of hot rolled section steel with the same unit weight.
