Factory Supplier H-type Steel H Beam Astm A36 Q345b H-beam Steel I-beam

description

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

introduce
The section shape is similar to an economical section profile of the capital Latin letter H, also known as universal steel beam, wide edge (edge) I-beam or parallel flange I-beam. The cross-section of H-beam usually includes two parts, the web plate and the flange plate, also known as the waist and the edge.
use
H-beams are widely used and are mainly used for:

various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and high temperature working conditions; requiring large bearing capacity and cross-section Large bridges with good stability and large span; heavy equipment; highways; ship skeletons; mine support; foundation treatment and embankment engineering; various machine components.

Classification

There are many product specifications of H-beam, and the classification methods are as follows. (1) According to the flange width of the product, it is divided into wide flange, middle flange and narrow flange H-beam. The flange width B of wide flange and middle flange H-section steel is greater than or equal to the web height H. The flange width B of the narrow flange H-beam is approximately equal to one-half of the web height H. (2) According to product use, it is divided into H-shaped steel beam, H-shaped steel column, H-shaped steel pile, and extremely thick flange H-shaped steel beam. Sometimes parallel leg channels and parallel flange T-beams are also included in the scope of H-beams. Generally, the narrow flange H-beam is used as the beam material, and the wide-flange H-beam is used as the column material. (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. Usually, products with a web height H above 700mm are called large, those with a height of 300 to 700mm are called medium, and those with a height of less than 300mm are called small. By the end of 1990, the world's largest H-beam had a web height of 1200mm and a flange width of 530mm.H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.
