While hot rolled steel is suitable for many manufacturing and fabrication applications, scale naturally forms on its surface during production. Hot Rolled Pickled and Oiled (HRPO) steel provides the strength and versatility of hot rolled carbon steel with a cleaner, smoother surface.
Ready-to-ship and competitively priced, our HRPO steel provides a practical balance of performance, surface quality, and value for a wide range of manufacturing and fabrication applications.
To provide a more desirable working surface, HRPO steel is produced by immersing hot rolled carbon steel in an acid bath to remove the scale, a process known as pickling. After the pickling is complete, a layer of oil is applied to the steel surface to prevent rust formation or oxidation.
HRPO steel bridges the gap between hot rolled and cold rolled steel, providing improved surface quality while accommodating heavier gauges.
Well suited for cutting, welding, forming, and bending, HRPO steel supports efficient manufacturing across diverse applications.
The protective oil coating helps reduce the risk of surface rust during storage, handling, and transportation before fabrication or finishing.
The scale-free surface of pickled and oiled steel provides a better starting point for painting, powder coating, and other finishing processes than hot rolled steel.
HRPO steel moves more smoothly across plasma and laser cutting tables, helping improve cutting efficiency and production flow.
As a hot rolled pickled and oiled steel supplier, Premium Steel Sales stocks a wide variety of HRPO steel products, including plate with custom cut-to-length options and a wide range of thicknesses, widths, and grades.
HRPO steel is popular for applications requiring a scale-free surface or for materials that need to be run in high-volume production environments. Among the industries that use HRPO steel are the following:
Sourcing flat rolled carbon steel is about more than finding available inventory. Premium Steel Sales draws on more than 30 years of industry experience and a nationwide network of mills, suppliers, and processors to provide material options that align with your application, timeline, and budget.
Reduce material costs by tapping into our large in-stock inventory, extensive market knowledge, and longtime steel-buying experience.
Achieve shorter lead times by sourcing from available inventory instead of relying on mill production schedules.
Choose from a wide range of material options that go beyond standard inventory and specifications to fit your application.
HRPO steel is hot rolled steel that has been pickled to remove mill scale and then coated with oil for protection against oxidation and corrosion. This results in a cleaner, smoother surface that is often preferred for fabrication, forming, welding, and finishing operations.
Yes, in many applications, pickled and oiled steel can be used as a direct replacement for hot rolled steel. It should be noted, though, that hot rolled usually cannot be used to replace HRPO when the application specifically requires it.
HRPO steel is commonly used for fabricated components, welded assemblies, brackets, structural products, agricultural equipment, material handling equipment, and other industrial products that benefit from a clean, scale-free surface.
Yes. HRPO steel is widely used for welding, forming, bending, cutting, and general fabrication. Its clean surface can improve consistency and efficiency during manufacturing processes, although some users prefer to avoid the smoke created by the oil layer during welding.
Yes. The scale-free surface of HRPO steel allows it to move smoothly across plasma and laser cutting tables, making it a popular choice for many fabrication operations.
The oil coating provides temporary protection against rust during storage and transportation, but HRPO steel is not intended for long-term corrosion resistance. For applications exposed to moisture or harsh environments, galvanized, galvannealed, or aluminized steel may be a better suited choice of materials.
Premium Steel Sales supplies HRPO steel in master coil, pre-cut sheets, and plate. Additional processing options may include slit coil, narrow-width coil, custom-sized finished blanks, off-pattern widths, and cut-to-length products (stretcher level and temper pass available).
If your application requires the strength and versatility of hot rolled steel with a cleaner, scale-free surface, Premium Steel Sales is ready to help. Contact our team for pricing on HRPO steel in coil, sheet, blanks, and custom processed forms.
