Steel Round Bars

Quick Detail:

Carbon Round steel bar refers to a solid long strip of steel with a circular cross-section.  Its specifications are expressed in diameter in millimeters (mm).

Carbon Round steel is divided into three types: hot rolled, forged and cold drawn.  The size of hot rolled round bar is 5.5-250 mm.

Among them: small round bars of 5.5-25 mm are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts;  round bars larger than 25 mm are Mainly used for the manufacture of mechanical parts and billets of seamless steel pipes Wait.

The composition of carbon round steel bars includes carbon, manganese, and other elements in small amounts. Carbon is the primary component and is responsible for the bar's strength and durability. Other elements, such as manganese, provide additional strength and increase the steel's ability to withstand stress. The carbon content in carbon round steel bars can vary from 0.05% to 2.5%, depending on the application and required strength. Carbon round steel bars are available in various sizes, ranging from 6mm to 500mm in diameter. The most common sizes used in construction and engineering applications are 12mm, 16mm, 20mm, 25mm, and 32mm. The length of the bar can also vary depending on the specific application. Bars can be cut to custom lengths or purchased in standard 6-meter lengths. The surface of carbon round steel bars can be smooth or have a raised pattern. Smooth bars are commonly used in applications where appearance is important, such as ornamental metalwork. Raised pattern bars, also known as ribbed bars, are used in construction applications where added grip is required, such as in the construction of reinforced concrete.
