1) Hot rolled H steel (GB1263-89)
Hot rolling H steel (GB1263-89) also called the wide leg I-steel, rolled by H section mill with the belt side. The characteristic is two legs parallel, and the leg inside do not have the ascent.
The H steel section shape is economical and reasonable, with good mechanics performance, when rolling; each spot on the section extends evenly, small internal stress. Compared with the ordinary I-steel, it has the merits of big section modulus; light weight, saves metals and so on. Used in construction, can cause the structure to reduce 30%-40%. Furthermore, because of the leg flank parallel and the leg end is the right angle, when assembling combines to the component, may save the welding, the riveted joint work load reaches 25%. commonly used big bearing capacity, large-scale construction with stability section (e.g. high-rise construction, workshop and so on), the bridge, the ships, lift ,transport machinery, the mechanical foundation, the support , the foundation pile and so on.
Types: A. wide flange H Steel (HK); B. Narrow flange H steel (HZ);
C. H steel peg (HU)
Expression: expressed by the weight, label a, b, c ...... (For example: HK200C#). Also may use height (H) × width (B) ×ventral plate thickness (t1) × lifting surface thickness (t2), like HK200×206×15.0×25.0.
Specifications: wide flange SteelHK100#-HK900#, Narrow flange H steel HZ80#-HZ600#, H steel peg HU200#-HU500#
(2)H steel for welding (YB3302-81)
Light H steel for welding is welded by high frequency electric welding technics, or carbon dioxide shielded welding, manual welding and so on.
Used in MIG/TIG welding, in the welding structure of pillars, girders, purlines, etc. The types are presented by height (H)*width (b) in mm, range 100*50-454*300mm
