H-shaped steel is an economical cross-section high-efficiency profile with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.

Channel steel is a long strip of steel with a groove-shaped cross-section. It belongs to carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Angle joint sheet, also known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle. There are equilateral angle steel and unequal angle steel. The two sides of an equilateral angle are equal in width. Its specifications are expressed in millimeters of side width x side width x side thickness.

Rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel after process treatment. Generally, the strip steel is unpacked, flattened, crimped, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length.

Galvanized square pipe is a hollow square cross-section steel pipe with a square cross-section shape and size made of hot-rolled or cold-rolled galvanized strip or galvanized coil as a blank after cold bending and then high-frequency welding. , or a galvanized square tube made by hot-dip galvanizing the pre-made cold-formed hollow steel pipe.

The steel sheet pile is a kind of steel structure with linkages on the edge, and the linkages can be freely combined to form a continuous and compact retaining wall or water retaining wall.

The cold-formed steel sheet pile is continuously rolled and formed by the cold-formed machine, and the side locks can be continuously lapped to form a steel structure of the sheet pile wall. Cold-formed steel sheet piles are made of thinner plates (commonly used with a thickness of 8mm to 14mm) and processed by cold-formed forming machines. Its production cost is low and the price is cheap, and the sizing control is also more flexible.
