HRPO Steel Fabrication Services

Hot rolled pickled and oiled steel (HRPO) has been processed to remove surface impurities and descaled.

HRPO steel sheets have improved workability and ductility and create cost-saving opportunities associated with downstream processing like bending, forming, welding, laser cutting, and painting.

At Alliance, our extensive inventory of HRPO steel sheets has been descaled and oiled to extend longevity in corrosive environments. Request your quote today!

What is HRPO?

Hot rolled steel products will scale in contact with oxygen and water vapor after the rolling process.

Pickling is a metal surface cleaning process in which an acid bath (either sulfuric or hydrochloric) removes rust, stains, and unwanted contaminants that could interfere with subsequent fabrication processes like bending, forming, painting, and stamping.

After the pickling process, steel can oxidize after extended exposure to oxygen and atmospheric moisture. Finally, the oil film is applied to the steel to create a protective shield.

What are HRPO applications?

Hot rolled pickled and oiled steel sheets and coils are often used as an alternative to cold rolled steel due to a decreased cost. HRPO is well suited for many applications while offering improved workability and availability.

Fiber Lasers


Frequently Asked Questions

Alliance has an industry-leading inventory of HRPO and can process to your specification.  

Common grades of HRPO are:

ASTM A1011 Hot Rolled Pickled Steel

Alliance stocks ASTM A1011 Hot Rolled Pickled Steel in:

  • Commercial Steel (CS) & Drawing Steel (DS) Types A and B
  • Structural Steel (SS): Grades 30-55
  • HSLA (High Strength Low Alloys)
  • UHSS (Ultra-High-Strength Steel): Grades 40 - 100

ASTM A1018 Hot Rolled Pickled Steel

Alliance stocks ASTM A1018 Hot Rolled Pickled Steel in:

  • Commercial Steel (CS) & Drawing Steel (DS) Types A and B
  • Structural Steel (SS): Grades 30-45
  • HSLA (High Strength Low Alloys)
  • UHSS (Ultra-High-Strength Steel): Grades 40-100

ASTM A36 Hot Rolled Pickled Steel

ASTM A36 Steel Plate is one of the most common grades of steel used in structural applications. The ASTM A36 standard covers low-carbon steels that are commonly used in construction, manufacturing, and other industries. It is considerably soft for easy forming, machining, and welding. Heat treatment has less effect on ASTM A36 steel material.
