Round bars that are produced through hot rolling are an indispensable and flexible material in a wide range of industries. They are utilized extensively in manufacturing, construction, automotive, and various other fields, providing exceptional durability, strength, and dependable performance for multiple applications. The process of creating these bars involves heating steel at high temperatures and shaping it through rolling to meet the specific requirements. Consequently, the outcome is an output that displays outstanding surface quality, strict tolerances, and consistent functionality.

The production of hot rolled round bar involves passing the steel through a rolling process at temperatures above its recrystallization point. This method achieves a greater degree of malleability and workability in the final product, making it an ideal choice for a variety of applications in the manufacturing, fabrication, and repair sectors. It can be seamlessly welded and fabricated to suit the user's needs. The sizes of hot rolled round bars range from as small as 1/4" diameter to as large as 12" diameter, offering a wide range of applications. It is a perfect alternative to cold rolled round bar when precise tolerances are not strictly necessary.

Hot rolled steel round bar provides a wide variety of beneficial features, including:
* Slightly rounded edges and corners (due to shrinkage).
* Slight distortions, where cooling may leave slightly trapezoidal forms rather than perfectly squared angles.
* Scaled surfaces due to the extreme temperature cooling process.

Used for petrochemical industry, fluid delivery, nuclear power plant, geological drilling, power plant and heat exchanger and so on.
