Product details

Hot rolled steel 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.

Hot rolled steel round bar 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. Contact us for more information about metal types, shapes and grades available.
