A-366/1008 Commercial Quality Mild Steel
We have A36 carbon steel (mild steel) in three surface finishes based on thickness. Cold Rolled Carbon Steel, Hot Rolled Carbon Steel and Hot Rolled Pickled and Oiled Carbon Steel (HRP&O). Mild steel is the go-to choice for fabricators, welders, machinists, prototypers, and anyone else who needs a strong, reliable part that is easy to work with.
Our cold rolled carbon steel (also known as mild steel) is our favorite material to work with by far. Our cold rolled steel is the go-to choice for fabricators, welders, machinists, prototypers, and anyone else who needs a strong, reliable part that is easy to work with.
Our hot rolled carbon steel is commercial mild steel, found in most industries as it offers good weldability and machinability. HRP&O steel is much smoother and easier to finish than cheaper “mill finish hot roll” that most steel centers sell. Anyone who has ever tried to remove mill scale from some cheap angle iron will know what we’re talking about.

Mild steel is cut using oxygen as an assist gas, so some slight oxidation may be present on cut edges. Oxidation is easily removed using muriatic acid or mechanical methods such as a wire brush or tumbler.
PLEASE NOTE
Laser-cut materials may have a small amount of dross (burr) on the underside of your part(s). This is a normal occurrence from the cutting process. Due to manufacturing variables, your parts may also have small cosmetic imperfections/scratches.
