Hexagonal steel is a kind of section steel, also known as hexagonal bar, bar with regular hexagonal section. The nominal size is the opposite side length S. Hexagonal steel can be used to form various stress components according to the different needs of the structure, and it can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Special-shaped pipes are generally distinguished according to the broken section and overall shape. They can be generally divided into elliptical special-shaped pipes, triangular special-shaped pipes, hexagonal special-shaped pipes and so on. Diamond shaped pipe, stainless steel pattern pipe, stainless steel U-shaped pipe, D-shaped pipe, stainless steel elbow, S-shaped pipe elbow, octagonal shaped pipe, semi-circular shaped steel circle. Hexagonal shaped steel pipe with unequal edges, plum blossom shaped steel pipe with five petals, double convex shaped steel pipe, double concave shaped steel, melon seed shaped steel pipe, conical shaped steel pipe, corrugated shaped steel pipe, etc.

Classification of hexagon tubes:
Classification of material used for hexagonal steel pipes: 20, 45, 16 manganese and other different materials have different uses.

Hexagon tubing is an outer hexagonal steel pipe. It is a kind of special-shaped steel pipe. It is mostly used in the processing of nuts and mechanical fittings. Hollow hexagonal bar is the general name of the steel pipe with outer hexagonal section and inner circular section. It has welded and seamless special-shaped pipe. Because of the material relationship, can be divided into ordinary carbon steel heterosexual steel pipe, hexagon steel tube.
