H beams for steel structure buildings materials

The characteristics of H type steel

H steel is a steel with a new economic construction. H type steel cross section shape is reasonable in economy, good mechanical properties, rolling section of each point on the extension of uniform, small internal stress, compared with ordinary I-beam section modulus, with large, light weight, saving metal advantages, can make the structure reduce 30-40%; because of its inner and outer side legs parallel leg end is a right angle and assembled components, welding, riveting work can save up to 25%. Commonly used in the requirements of bearing capacity, good stability of large section of the building (such as buildings, high-rise buildings, bridges, ships, etc.), lifting the transport machinery, equipment support, foundation pile foundation, etc..

H steel is a kind of mechanical properties by optimization of the development section of I-beam and become more economical section steel is excellent, especially the section with the letters "H" the same name. Its features are as follows:

The flange width, lateral stiffness.

The anti bending ability, than the I-shaped steel is about 5%-10%.

The flange surface parallel connection makes two, convenient manufacture and installation.

We compared with the welding I-steel, low cost, high precision, small residual stress, no welding material and welding seam detection expensive, saving steel structure fabrication cost about 30%.

The same section load. The structure of hot rolled H steel than the traditional steel structure weight 15%-20%.

We compared with the concrete structure, the structure of hot rolled H steel can be increased 6% use area, and the structure weight 20% and 30%, reducing the internal force of structure design.

The H type steel can be processed into a T type steel castellated beams can be combined, forming a variety of cross section form, design and manufacture of greatly satisfy the demand of engineering.
