H section steel is divided into hot rolled H section steel and welded H section steel (H).
The hot rolled H section steel is divided into three types: wide flange H section steel (HM) and narrow flange H section steel (HN) in the middle flange.
HW is H section steel height and flange width is basically equal; Mainly used in reinforced concrete frame column steel core column,Also known as stiff steel column; Steel structure is mainly used for column HM H section steel height and flange width ratio is about 1.33~~1.75 mainly in steel structure: steel frame column is used as frame beam in frame structure under dynamic load;
The HN of the equipment platform is H steel height and The ratio of flange width is greater than or equal to 2, which is mainly used in beam; the use of I-beam is equivalent to HN section steel; the main materials of H section steel are Q235B、SM490、SS400、Q345、Q345B and so on.
