Round steel is divided into three types: hot rolled, forged and cold drawn. The specification of hot-rolled round steel is 5.5-250mm. Among them: 5.5-25mm small round steel is mostly supplied in straight bars, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25mm is mainly used to manufacture mechanical parts and seamless steel pipe billets.

Round bar is exactly as it sounds; a long, cylindrical metal bar. Round bar is available in a variety of metals including hot rolled or cold rolled steel, stainless steel, aluminum, alloy steel, brass and more; and in many different diameters ranging from 1/4″ up to 24”.

Steel Round Bars

Steel round bars are available in hot rolled or cold rolled. Hot rolled round bar is typically used for applications like construction where finish and precise dimensions aren’t a priority. Conversely, cold rolled round bar is used for applications where a superior surface finish and exact dimensions are essential. Some common applications of steel round bar include frameworks, supports, braces, shafts, and axles.

Stainless Steel Round Bars

Stainless steel round bars are highly corrosion resistant. The stainless steel will tolerate high levels of acidity and can be used in chlorine bearing environments or alkaline solutions.

Aluminum Round Bars

Aluminum round bars possess light weight and strong corrosion resistance, while being easy to machine and cut. Common applications of aluminum round bar include supports, trim, shaft, braces, pins, and dowels.

Brass Round Bars

Brass round bars are used when strength, electrical conductivity, corrosion resistance, and spark resistance are important. Brass is easy to machine and has an attractive sheen when polished. Some examples of brass bar applications are marine hardware, instruments, fasteners and fittings.
