We offer two types of Mild Steel Round Bar, both Hot Rolled and Cold Rolled. Hot Rolled Round Bar typically refers to the round bar with rough surface that is used for application including fabrication, manufacturing and repair where precise tolerances aren’t a priority. Products that we offer include Black Shaft & Carbon Steel Shaft. On the contrary, Cold Rolled Round Bar has a smoother finish than hot rolled round bar and it is commonly used in machining and industrial industries where precision dimensions are required. Its representative includes Polish Shaft & Free Cutting Shaft. We supply Mild Steel Round Bar in many different diameters, ranging from 1/4″ up to 24”. We provide Mild Steel Round Bar products in either full length or in any size you require.
