I-steel is a section shape similar to the Chinese character "gong" section steel, because of its section shape named. It consists of two parallel flange (flange) and a vertical web (web) in the middle, and is widely used in construction, bridge, machinery and other fields.

H-shaped steel consists of two parallel flange (flange) and a vertical web (web), cross-section is "H" shape.Flange and web thickness can be the same or different, depending on the model and use. Because of its efficient bearing performance and a wide range of applications, it has become one of the commonly used steels in construction and engineering structures.

Angle steel, also known as Angle iron, is a long strip of steel with vertical angles on both sides. There are equal angles and unequal angles. The two sides of an equilateral Angle are equal in width. Its specifications are expressed in millimeters of side width * side width * side thickness.

Flat Steel is a long strip of steel with a rectangular cross-section, thin thickness and narrow width, belonging to a type of section steel. Its production process usually includes hot rolling, cold rolling or forging, and is widely used in construction, machinery manufacturing, hardware processing and other industries.

U-shaped steel for mining is a type of steel specially used for mine support, named for its cross section shape similar to the letter "U". It plays a supporting and reinforcing role in underground engineering such as mine roadway and tunnel engineering, which can effectively prevent landslide and geological deformation and ensure mine safety production.

U-shaped steel is a kind of steel with a cross-section shape similar to the letter "U", usually made by hot rolling or cold bending process, and is widely used in construction, machinery manufacturing, vehicle manufacturing and other fields.
