H purlin introduction

H-section steel purlin is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is the same as the English letter "H". Since the various parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.

H-beam application

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

◆Steel structure bearing support for industrial structures;

◆Steel piles and supporting structure of underground engineering;

◆The structure of industrial equipment such as petrochemical industry and electric power;

◆Long-span steel bridge components;

◆Frame structure of ship and machinery manufacturing;

◆Girder brackets for trains, cars and tractors;

◆Port conveyor belt, high-speed baffle bracket;

H-beam steel is a kind of economical cross-section steel, which is widely used in industries, construction, bridges, oil drilling platforms, etc.

H-beams are divided into hot-rolled H-beams and welded H-beams (H). Hot-rolled H-beams are divided into wide-flange H-beams (HW), middle-flange H-beams (HM) and narrow-flange H-beams (HN). Three kinds. .

The main materials of H-beam are Q235B, SM490, SS400, Q345, Q345B, etc.
