Product Details

Hot rolled round bars are a versatile and essential material in many industries. They are widely used in construction, manufacturing, automotive, and other fields, delivering strength, durability, and reliability for a wide range of applications. These bars are produced by heating steel at high temperatures and then rolling it into a shape that meets the required specifications. The process results in a product with excellent surface quality, tight tolerances, and consistent performance.

Hot rolled round bar is formed through a metal rolling process where the steel is pressed at temperatures above the its recrystallization threshold. This makes the steel easier to form, and results in products that are easier to work with. It has applications across many industries including fabrication, manufacturing and repair. It can be easily welded and fabricated. Hot rolled round bar can be purchased in sizes as small as 1/4″ diameter and as large as 12″ diameter. It can be used in place of cold rolled round bar in situations where precise tolerances are not required.

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.
