As one of the commonly used types of steel, hot-rolled H-beam is widely used, then, hot-rolled H-beam specifically what are the characteristics of it, the following xiaobian together with you to analyze：
Hot-rolled H-beam is a new type of economic construction steel.H-shaped cross-section shape is economically reasonable, good mechanical properties, rolling cross-section on each point extends more uniform, small internal stress, compared with ordinary I-beam, with a cross-section modulus, light weight, saving the advantages of metal, can reduce the building structure 30 ~ 40%; because of its parallel legs inside and outside, the leg end is at right angles, assembledCommonly used in large-scale buildings(such as factories, high-rise buildings, etc.), as well as bridges, ships, lifting transport machinery, equipment Foundation, stent, foundation piles.
Hot-rolled H-shaped steel is a kind of Section mechanical properties of the development of the optimization of the I-shaped steel is more excellent economic section steel, especially the section with the letter " H " the same name.Its features are as follows：
Flange width, lateral stiffness, bending ability, than the I-beam about 5% -10%.
Parallel to each other so that the two surfaces of the flange connection, processing, easy to install.
Compared with the welding of I-beams, low cost, high precision, small residual stress, without expensive welding materials and weld inspection, steel production cost savings of about 30%.
Under the same cross-sectional load, hot-rolled H-beam structure is 15% -20% lighter than traditional steel structure.
Compared with the concrete structure, hot-rolled H steel structure can be increased by 6% of the area of Use, and the structure of weight reduction of 20% to 30%, reducing the internal force of the structure design.
The above is the flame Xin Sen domain xiaobian for you to introduce some of the contents of all about the characteristics of hot-rolled H-beam, I hope to help you!
