In China, the steel for steel structure is mainly plate and applications of hot rolled H beam (RH) in steel structure is growing slowly. The use level of RH accounts for only 15% of total amount of H beam, which is relatively lower and the rest is welded H beam (BH). In this article, the specifications, types, production processes, residual stresses, microstructure at R corner, advantages and disadvantages as well as future development trends of BH and RH are compared and analyzed. Moreover, several countermeasures for the application bottleneck of RH in construction steel structure are proposed.
