If you are building something that has to be super-strong and durable, hot-rolled, pickled & oiled (also known as HRP&O) mild steel is the way to go. Our fabrication and welding customers love this material since it's so reliable and easy to work with.

  • Our favorite material when parts need to be indestructible.
  • Very strong, very heavy.
  • Welds beautifully.
  • Pickled & oiled finish reduces tough mill scale
  • Easy to thread, machine, drill etc.
  • Looks great painted, powder coated or clear coated.

For thicknesses of .188" and .250", we offer hot-rolled pickled and oiled (HRP&O) steel plate, otherwise known as A36.

If you are looking for thinner material, check out our cold-rolled mild steel.

HRP&O is made of low carbon steel that is found in most industries as it offers good weldability, machinability, and can be heat treated to harden its surface. 

Hot-rolled pickled and oiled 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. The pickling process removes the scale from the hot rolled steel surface resulting in a clean, uniform surface. After the scale is removed, an oil film is applied to guard against rust.

Hot-rolled 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.

Because HRP&O is so heavy, we offer a limited selection of sizes. If you need something larger than what's available on the site, please let us know and we'll get you a quote and shipping costs.
