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.

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.
