What are the applicable scope and characteristics of H-shaped steel?

The European standard H-shaped steel H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength to weight ratio. It is 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.

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

1. Steel structure load-bearing brackets for industrial structures

2. Steel piles and support structures for underground engineering

3. Structure of industrial equipment in petrochemical and power industries

4. Long span steel bridge components

5. Ship and machinery manufacturing frame structure

6. Train, car, tractor beam bracket

7. Port conveyor belt, high-speed baffle bracket

H-shaped steel is an economical section steel with better mechanical properties developed from the optimization of I-shaped steel, especially named after the same section as the English letter "H". Its characteristics are as follows:

1. Wide flange and high lateral stiffness. Strong bending resistance, approximately 5% -10% higher than I-beam.

2. The two surfaces of the flange are parallel to each other, making it easy to connect, process, and install.

3. Compared with welded I-beams, it has low cost, high accuracy, low residual stress, no need for expensive welding materials and weld seam testing, and saves about 30% of steel structure production costs.

4. Under the same cross-sectional load, the weight of hot-rolled H-steel structures is reduced by 15% -20% compared to traditional steel structures.

5. Compared with concrete structures, hot-rolled H-steel structures can increase their usage area by 6%, while reducing their self weight by 20-30%, reducing the internal force of structural design.

6. H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sectional forms, greatly meeting the needs of engineering design and production.
