H-beam is a more optimized cross-sectional area distribution, more reasonable than the economic section of high-efficiency profiles, because of its section and the English letter "H" the same name. Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure in all directions, and has been widely used.

The hex bars have good machinability,mechanical features and close dimensional precision as it is rolled steel.Hex bar is typically employed in heat exchangers, chemical equipment,aerospace parts,tanks and marine equipment,among its many uses.They are used in various industrial and commercial requirements and are supplied worldwide

Stainless steel I-beams are made of 201(1Cr17Ni5Mn6N), 202(2 Cr13Mn9Ni4), 301(1 Cr17Ni7), 303(Y1Cr18Ni9), 304(OCr18Ni9), 304L (03 Cr19Ni10), 316(0 Cr17Ni12Mo2), 316L(00 Cr17Ni14Mo2), 321 (1 Cr18Ni9Ti), 420( 2cr13), 310S(0 Cr25Ni20), etc. The chemical composition of stainless steel I-beams belongs to general structural rolled steel series, the main test indexes were C, Mn, P and S. According to different grades, the content varies, the approximate range is C<0.08%, Mn: 2.0, P<0.035%, S<0.03%.

Carbon steel, on the other hand, has far lower chromium levels, and is instead a carbon-iron alloy with only a few other materials, if any, as part of its makeup. As a result, it can be referred to as ‘low-alloy’ steel. Both stainless steel and carbon steel feature this basic composition, but carbon steel can be defined by its carbon content. This is normally around 2-2.5%, however this often varies. Though susceptible to rust unlike stainless steel, carbon steel is often cheaper and has its own varying mechanical properties based on carbon content.
