Brief Introduction

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

The inner and outer flanges of H-beam are parallel or nearly parallel, and the end of the flanges is at a right Angle, hence the name "parallel flange I-beam".H-beam web thickness is smaller than the same high webs of ordinary I-steel, flange width is larger than the same high webs of ordinary I-steel, so it is also named wide edge I-steel.Depending on the shape, the section modulus, moment of inertia and the corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight.

Specification

Used in different requirements of the metal structure, whether it is subjected to bending moment, pressure load, eccentric load shows its superior performance, can be compared with ordinary I-steel greatly improve the bearing capacity, metal saving 10% ~ 40%.H-beam steel has wide flange, thin web, many specifications and flexible use.

It can save 15% ~ 20% of metal in various truss structures.Because the inside and outside of the flange are parallel and the edge ends are at right angles, it is easy to assemble and assemble into various components, thus saving about 25% of the welding and riveting workload, greatly speeding up the construction speed and shortening the construction period.
