H型鋼

H section steel
H type steel is an economic efficient section material with optimized cross section area allocation and more reasonable ratio of strength to weight. It is named because of its letter "H" cross section. Since its different parts are of orthogonal configuration, h-beam has advantage of good bending capacity, simple construction, cost saving and structure light weight etc., has been widely used.

H-beam is divided into:
The flange wide type (HW)
The flange middle type (HM)
The narrow flange type (HN)
Thin-wall h-beam type (HT)
H section steel pile type (HU)

H-type steel, optimized from I-shaped steel, is economic cross section steel with better cross-section mechanical performance. Especially, it is named because of its letter "H" shape section.
Its characteristics are as follows:
1. Wide flange, large lateral stiffness and strong anti-bending ability.
2. Two parallel flange surfaces enable easy and simple connection, processing and installation.
3. Compared with welding joist steel, H-type has lower cost, high precision, small residual stress. There is no need for expensive welding material and welding seam detection, so the steel structure production is cost saving.
4. Under the same cross section load, reduction weight of hot rolled H-type steel structure can be % more than the traditional steel structure.
5. Compared with concrete structure, hot rolled H steel structure can increase 6% using area. Meanwhile, its self-reduce weight also reduces the internal structure design force.
6. H section steel can be processed into T steel. Honeycomb beam can be formed into various sorts of cross section by combination, which greatly meets the demand of engineering design and production.
