Specification: Q355/Q420
Low-alloy high-strength steel (such as Q355 and Q420) is used to construct steel beams, columns, trusses, purlins, etc., to meet the requirements of large spans and high load-bearing capacity. Super-large hangars will utilize steel pipe trusses or box girders to enhance structural rigidity.
