I-beams are mainly divided into ordinary I-beams, light I-beams and wide-flange I-beams. According to the height ratio of the flange to the web, it is divided into wide, medium and narrow wide flange I-beams. The specifications produced by the former two are No. 10-60, that is, the corresponding height is 10 cm-60 cm. At the same height, the light I-beam has narrow flange, thin web and light weight. The wide-flange I-beam is also called H-beam. The cross section is characterized by two legs parallel and no slope inside the legs.

H-beam is a kind of Economic section steel, which sectional area distribution is more optimized, the ratio of strength to weight is more reasonable, Mechanical properties of section is more better. It is developed from the I-section steel optimization of a better section mechanical properties of the economic section steel, because its section is same as the English letter "H" ,so be named as H-Beam. Because the various part of H-beam is arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, so it has been widely used.
H-beam as a new type of economic construction steel. The section shape of H-beam steel is economical and reasonable, the mechanical properties are good, and the elongation of each point on the section is uniform and the internal stress is small. Compared with the ordinary I-beam steel, it has the advantages of more large section modulus,more light weight and more saving metal, which can reduce the building structure by 30-40%. And because its legs inside and outside parallel, leg end is a right Angle, assembled into components, can save the workload of welding and riveting up to 25%. It is often be used in large buildings (such as workshops, high-rise buildings, etc.), as well as Bridges, ships, lifting and transportation machinery, equipment foundation, supports, foundation piles, etc.

It is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal sides and equal thickness and unequal sides and unequal thickness. The delivery length of angle steel is divided into two types: fixed length and double length. The selection range of fixed length for domestic angle steel has four ranges: 3~9m, 4~12m, 4~19m, and 6-19m according to the different specifications. The length of angle steel produced in Japan ranges from 6m to 15m.

Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly blunt edges. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked thin plates. Main application: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and it can be used as a structural part of a house frame and an escalator in a building.
