Square steel can be divided into hot rolled and cold rolled two kinds

Hot rolled square steel refers to rolled or processed into a square section of steel, hot rolled square steel side length 5-250mm.

Cold drawn square steel refers to cold drawn steel forged in the shape of a square, cold drawn square steel refers to a square cold drawn steel, cold drawn square steel side length of 3-100mm. Cold drawing steel is the use of cold extrusion technology, through the precise mold, all kinds of high precision, smooth surface of round steel, square steel, flat steel, hexagonal steel and other special-shaped steel.

Square steel has high strength and rigidity, can bear large load and deformation. Therefore, square steel is often used in the manufacture of machinery and equipment, Bridges, building structures and other occasions to withstand heavy loads. For example, in the field of architecture, square steel is often used to make the main frame of steel structure houses, which can ensure the stability and safety of the houses.

Square steel has good plasticity and weldability, can be easily processed and connected. Therefore, Square Steel is often used in the manufacture of various parts and accessories, such as auto parts, machinery parts, pipes, etc. In addition, square steel can also be processed by cold bending, hot bending and other processing methods, made into various shapes of components, such as Angle steel, channel steel, I-steel, etc., used for building and mechanical equipment construction and support.

Square steel also has good corrosion and wear resistance, can be used in harsh environment for a long time. Therefore, Square steel commonly used dry manufacturing Marine engineering, chemical equipment, mining equipment and other need to resist corrosion and wear occasions. For example, in the field of ocean engineering, square steel is often used to make offshore platforms, submarine pipelines and other facilities, which can withstand the erosion of seawater and the impact of waves.

High accuracy

The use of high quality carbide mold and professional mold repair personnel to ensure accurate and uniform tolerances.

Smooth surface

Advanced cold extrusion technology makes the surface of cold drawn steel products smooth and bright.

Substantial material saving

Cold drawing process is the cold extrusion deformation of raw materials to the required shape, specifications and tolerances, the consumption of raw materials is very little, compared with the use of traditional lathe machining and cutting of the material consumption, the material saved by cold drawing steel is very considerable, especially when the material consumption is large, the material cost saving is more significant.

Machining time and machine saving

Due to the accuracy and good surface condition, cold drawn steel products can be directly used, such as spraying, sand, bending, drilling, and also can be directly electroplated after fine drawing according to the actual requirements, which saves a lot of machining time and saves the cost of configuration of processing machinery.
