What is an H-beam?

European standard H-shaped steel H-shaped steel

H-beam is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength to weight ratio, named after the same section as the English letter "H". Due to the fact that all parts of H-beam are arranged at right angles, H-beam has advantages such as strong bending resistance, simple construction, cost savings, and light structural weight in all directions, and has been widely used.

Applicable scope of H-shaped steel

H-shaped steel is mainly used for beam and column components in industrial and civil structures.

◆ Steel structure load-bearing brackets for industrial structures

Steel piles and support structures for underground engineering

Structure of industrial equipment in petrochemical and power industries

◆ Long span steel bridge components

◆ Ship and machinery manufacturing frame structure

◆ Train, car, and tractor beam brackets

◆ Port conveyor belt and high-speed baffle bracket

H-beam is an economical cross-section steel widely used in industries, buildings, bridges, oil drilling platforms, etc. It is predicted that the demand for H-beam in China was about 2.5 million tons in 2005 and 5 million tons in 2010. However, the current annual production capacity of H-beam in China is 1.2 million tons, and the market demand is very large

Introduction to H-beam

H-beams are divided into two types: hot-rolled H-beams and welded H-beams (H). Hot-rolled H-beams are further divided into three types: wide flange H-beams (HW), medium flange H-beams (HM), and narrow flange H-beams (HN)..

HW is the height and flange width of H-shaped steel that are basically equal; Mainly used for steel core columns in reinforced concrete frame structures, also known as rigid steel columns; Mainly used for columns in steel structures

HM is an H-shaped steel with a height to flange width ratio of approximately 1.33 to 1.75, mainly used in steel structures as steel frame columns and as frame beams in frame structures under dynamic loads; For example: device platform

HN refers to the ratio of H-shaped steel height to flange width greater than or equal to 2, mainly used for beams; The use of I-shaped steel is equivalent to that of HN shaped steel;

The main materials of H-shaped steel include Q235B, SM490, SS400, Q345, Q345B, etc
