H-beam has parallel or near-parallel flanges on the inner and outer sides, and the end of the flanges is at a right angle, so it is named parallel flange I-beam.The thickness of the web of

H-beam is smaller than that of the ordinary I-beam with the same height of the web, and the width of the flange is larger than that of the ordinary I-beam with the same height of the web,

so it is also named wide flange I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are significantly better than the same

single-weight ordinary I-beam. Used in different requirements of the metal structure, whether it is to withstand bending moment, pressure load, eccentric load shows its superior

performance, can be compared with the ordinary I-beam greatly improve the load-bearing capacity, saving metal 10% ~ 40%. H-beam wide flange, thin web, specifications, flexible use,

used in a variety of truss structure can save 15% ~ 20% of the metal. Due to the parallelism between the inner and outer sides of the flange, the edge end is at right angle, it is easy to

assemble and combine into all kinds of components, thus it can save welding and riveting workload of about 25%, and it can greatly speed up the construction of the project and shorten

the construction period.
