Since the steel at high temperatures and long loads, steel companies, its breaking strength than the short-term strength decreases more, steel canopy, so the steel, steel under long-term high temperature, to measure the long term strength. Steel will automatically harden over time, become brittle, or "aging" phenomenon. Steel under low temperature loads to test its toughness. Steel editor refers to steel sheet and hot rolling, cold-formed or welded sections connected together by connecting members and deliver formal structure can withstand the loads. With light weight steel system, industrial manufacturing, quick installation, short construction period, seismic performance, fast return on investment, less environmental pollution and other comprehensive advantages, compared with reinforced concrete structure, but has a "high, big, light" three aspects of the development of the unique advantages.
