1. H-beam
H-beam has three common types: HW, HM and HN. HW is a common type, HM is a wide and flat type, and HN is a narrow flange type. At the same time, the industry also classifies the cross-section type of the European standard H-beam HEB as a mid-flange H-beam
2. I-beam
Its cross-section is I-shaped, and is divided into ordinary I-beams and light I-beams, among which ordinary I-beams are suitable for structures with large spans and large loads; light I-beams are suitable for making light structures and cantilever structures.
3. Angle steel
Equal-leg angle steel: The two sides are equal in width and are often used to build frame structures, support and connect.
Unequal-leg angle steel: For example, Japanese standard unequal-leg angle steel has specifications such as 1007510, which can also be used for some building structure construction needs.
4. Channel steel
The cross-section of the channel steel is a channel shape, which is suitable for making light beams, columns and other structures, and can be divided into hot-rolled channel steel, etc.
5. Round steel
It has a circular cross section and is often used to make bearings, mechanical parts, etc.
6. Square steel
Its square cross section is its characteristic and is widely used in the fields of making mechanical parts, building components, etc.
7. Threaded steel
It has a cross section with a threaded texture and is mainly used to make concrete reinforcement, bolts, etc. It is widely used in the construction industry
