I-shaped cross section rolled iron beams, steel beams or steel beams; also refers to a combination of beam-shaped cross-section, in particular for steel structures (such as steel buildings) in the beams. S235JR / J2 / J0 beam with stable performance, reasonable structure, strength and stiffness, low steel strength, toughness, ductility and weld-ability and other characteristics, widely used in various building structures, bridges, vehicles, brackets and machinery . S235JR / J2 / J0 beam cross-section is symmetrical, mechanical properties of the phenomenon appears more stable, at the same time, the stability of the same type of steel I-beam and better!
