H-beam is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio.

 

〣steel H beam details

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

〣Advantages of H beam steel

The inner and outer flanges of H-beams are parallel or nearly parallel, and the ends of the flanges are at right angles, hence the name parallel flanged I-beams. The thickness of the web of H-beam is smaller than that of ordinary I-beams with the same height of the web, and the width of the flange is larger than that of ordinary I-beams with the same height of the web, so it is also named wide rim I-beams. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight. Used in different requirements of the metal structure, whether under bending moment, pressure load, eccentric load show its superior performance, can greatly improve the bearing capacity than ordinary I-steel, metal saving 10% ~ 40%. H beam has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% metal in various truss structures. Because the flange is parallel inside and outside, and the edge end is at a right Angle, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting work, and greatly accelerate the construction speed of the project and shorten the construction period.

〣H-section steel for use

Due to the above advantages, H beam is widely used in: various civil and industrial building structures; A variety of long-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and high temperature working conditions; Large Bridges with large bearing capacity, good cross-section stability and large span are required; Heavy equipment; A highway; Ship skeleton; Mine support; Foundation treatment and dam engineering; Various machine components.
