Mild Steel Square Bar Hot Rolled carbon bar

There are many specifications of square steel, which are mainly distinguished according to their cross-sectional dimensions. Generally speaking, the larger the cross-sectional size of square steel, the stronger its bearing capacity. Common square steel specifications are 8#, 10#, 12#, 14#, 16#, etc., where the numbers represent the section width.

The manufacturing process of steel square bar includes hot rolling and cold drawing. Hot-rolled square steel is made by heating the billet to a certain temperature and pressing it through rolling machinery. The surface of hot-rolled square steel is relatively rough, but its mechanical properties are better. Cold-drawn square steel is made by cold-working hot-rolled square steel. Its surface is smooth, but its strength and toughness are slightly lower than hot-rolled square steel.

The application fields of steel Square bar are very wide. In the field of construction, square steel is often used in structures such as beams and columns, foundations, bridges, etc., and its strength and stability can ensure the safety of buildings. In the field of machinery manufacturing, square steel is often used to manufacture machine bases, bearing housings and other components. Its strength and durability can ensure the stability and service life of the machine. In the field of logistics, square steel is often used to make shelves, and its load-bearing capacity and stability can ensure the safe storage of goods.

A huge selection of Square Bar in a variety of metals. We will sell you any size and any quantity. Square Bar is widely used throughout the fabrication industry: frame work, braces, trim, shafts, axles, fittings, instruments, gym equipment, awnings, structures, and more.

Hot Rolled Steel Square Bar, used for all general structural fabrication and repairs in industrial maintenance, has a grainy finish with radius corners. It is easy to cut, weld, form, and machine. It is used in frame work, supports, shafts and axles.

Cold Finish aka Cold Rolled Steel Square, a low carbon steel product, is easily machinable and easy to weld, cut, and form. A cold finish steel square has a smooth surface wish sharp corners and is more dimensionally accurate than hot rolled bars. It is frequently used in shafts, machine mounts, fixtures, and more.
