  (1) Hot rolled H steel
Hot rolling H steel 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 *0%**0%. 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 *5%. 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: HK**0C#). Also may use height (H) × width (B) ×ventral plate thickness (t1) × lifting surface thickness (t2), like HK**0×**6×*5.0×*5.0.
Specifications: wide flange SteelHK**0#-HK**0#, Narrow flange H steel HZ*0#-HZ**0#, H steel peg HU**0#-HU**0#

(2)H steel for welding
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 **0******4***0mm
