H-beam, Tianjin, H-shaped steel, hot-rolled H-beam, Jinxi H-beam. 18622303953 Division I wholesale enterprises of Tianjin largest H-beam, perennial cash supply Maanshan Iron and Steel, Laiwu Steel, Rizhao, Jinxi, Changzhi, Wuhan Iron and Steel, Tangshan Iron and Steel Street, H-shaped steel, channel steel, I-beam, angle, welcome to purchase. The various parts of the H-shaped steel are at right angles to the arrangement of the H-beam in all directions bending ability, simple construction, saving cost and structural advantages of light weight, has been widely used. H-beam is a new kind of economic construction steel, mainly used for engineering, plant, machinery and equipment, bridges, highways, houses, etc.; mechanical and physical properties, the firm, the effect of energy conservation and environmental protection. H-beam is an economic section steel, widely used in industry, construction, bridges, oil drilling platforms. Due to the various parts of the H-beam are rectangular arrangement, H-beam bending ability, simple construction, saving cost and structural advantages of light weight, has been widely used in all directions. H-beam is divided into hot-rolled H-beam welding H-beam (H) are two types of hot-rolled H-beam is divided into wide-flange H-beam (HW) flange (HM), H-beam and narrow flange H-beam (HN) three. H-beam is optimized by the word steel development from a cross-section of the mechanical properties of excellent economic section steel, especially in cross-section with the English letter "H" is the same as the name. Its characteristics are as follows: ◆ wide flange lateral stiffness. ◆ bending ability, than the H-beam about 5% -10%. ◆ flange surface parallel to each other to make the connection, processing, and ease of installation. ◆ Compared with welded I-beam, low-cost, high accuracy, low residual stress, without the need for expensive welding materials and weld inspection, saving about 30% of the cost of steel production. ◆ load of the same cross-section. Hot rolled H steel structure is 15% to 20% lighter than the traditional steel structure weight. ◆ compared to the concrete structure, hot-rolled H steel structure to increase the use of 6% area, while the structure to reduce weight by 20% to 30% to reduce the structural design of the internal forces. ◆ H-section steel can be processed into T section, through a combination of castellated beams can form a variety of cross-sectional form, great to meet the engineering design and production needs.
