Ordinary beam beam length, light beam galvanized beam, due to cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the two main sleeve large difference beam standard, which makes it has a very limited range of applications. Beam used should be chosen according to the requirements of design drawings. 7, H-beam is a beam cross-section than the excellent mechanical properties of the steel section economy, because of its cross-sectional shape of the letters "H" of the same name. Hot-rolled H-shaped steel beam flange width ratio, lateral stiffness, flexural strength capacity. Under the same size H-beam processing heavier than a light beam. 8, I-beam flange surface is worn by the web portion becomes thick, thin exterior; H-beam flange is wearing surface, such as 9, HW HM HN H is known as H-beam, H-beam is welded; HW HM HN hot-rolled stainless steel I-beam, I-beam manufacturers, wholesale trade exhibition Bo (certified), Hefei Hefei exhibition beam provided by Bo Trading Company.
