H-section steel beam is a kind of economical section material with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is same as English letter "H". Due to the right-angle arrangement of all parts of H-beam, it has been widely used in steel structure buildings for its strong bending resistance, simple construction, cost saving and light structural weight in all directions.
Application Scope of H Beam
H beam is mainly used for beam and column members in industrial and civil structures.
H Beam Introduction
H beams are divided into hot-rolled H-beams and welded H-beams (H). Hot-rolled H-beams conclude wide-flange H-beams (HW), middle-flange H-beams (HM) and narrow-flange H-beams (HN). HW is H beam with basically same height and flange width, which is mainly used as core column in reinforced concrete frame structure, also called stiff steel column. HM is H beam that the ratio of the height and flange width is roughly 1.33~~1.75. Mainly used in steel structures as steel frame columns that bear dynamic loads, such as equipment platforms. HM is H beam that the ratio of the height and flange width is greater than or equal to 2. The main materials of H-beam are Q235B, SM490, SS400, Q345, Q345B, etc.
H beam is a new type steel beam for economic steel construction. The section shape of H-beam is economical and reasonable with good mechanical properties. The extension of each point on the section is more uniform and the internal stress is small during rolling. Compared with ordinary I-beams, it has the advantages of large section modulus, lightweight, and metal saving, which can make structure buildings’ weight reduced by 30-40%. Bellow are specific characteristics.
