H beam types

H beam types

Sometimes we will use H beams as crane rails for some special projects. we call it H beam rails. there are some H beam types. The classification methods are as follows：

1. According to the flange width of the product, it is divided into a wide flange, middle flange, and narrow flange H-beam.
2. According to the use of the product, it is divided into H-shaped steel beams, H-shaped steel columns, H-shaped steel piles, and H-shaped steel beams with extremely thick flanges.
3. According to the production method, it is divided into welded H-beam and rolled H-beam.
4. According to the size, it is divided into large, medium, and small H-beams.

The rail is a railway structure on which the wheels of the train roll on. The main functions are as follows:

Bear the wheel pressure and wear.

Disperse the wheel weight on the sleeper under the rail.

bear the repeated pressure.

Regardless of the weight of the rail, the mass ratio of the section should be roughly 42% for the head, 21% for the waist, and 37% for the bottom, and the height of the rail should be equal to the width of the bottom. When the head of the rail is worn up to 0.64 cm, the rail needs to be replaced immediately.

In addition, the steel structure dominated by a hot-rolled H-beam has a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. Some building structures in multiple earthquake zones. According to statistics, among the devastating earthquakes of magnitude 7 or above in the world, the steel structure buildings dominated by H-beams suffered the least damage. Increase the effective use area of the structure. Compared with the concrete structure, the cross-sectional area of the steel structure column is small, which can increase the effective use area of the building. Depending on the different forms of the building, the effective use area can be increased by 4-6%.
