H-section steel is a kind of economic section high-efficiency profile with more optimized section area distribution and more reasonable strength-weight ratio. It is named because its section is the same as the English letter "H".

Because H-beam is arranged at right angles in all parts, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions.

Based on the above advantages, H-shaped steel is widely used in various civil and industrial structures, various large-span industrial buildings and modern high-rise buildings, especially in areas with frequent seismic activity and under high temperature working conditions, requiring large bridges with large bearing capacity, good cross-section stability and long span, heavy equipment, highway, ship skeleton, mine support and foundation. Handling and dam engineering, various machine components.

2. Specification Category of H-section steel

C-section steel purlin has different specifications according to its height, and its length can be determined according to engineering design. However, considering transportation and installation conditions, the full length of purlin generally does not exceed 12 meters.

3. Processing flow of H-section steel

H-section steel can be produced by welding or rolling. Welding H-section steel is to cut strip with suitable thickness into suitable width and weld flange and web together in continuous welding unit. The processing flow of welded H-section steel is as follows:

Universal rolling mill is often used to roll H-beam in modern rolling production. The web of H-beam is rolled between the upper and lower horizontal rolls, while the flange is rolled between the side of the horizontal roll and the vertical roll at the same time. The processing flow of hot rolled H-beam is as follows:
