Hot Rolled Pickled and Oiled Steel
Mill scale on hot rolled steel has to come off before a part can take a clean weld or a coat of paint, and grinding or blasting it in-house eats hours your crew could spend building. Pickled and oiled steel arrives with that scale already gone.
Curtis Steel Company stocks hot rolled pickled and oiled (HRPO) coil and sheet in Texas, so manufacturers, stamping shops, and welding shops start with a clean surface and put their labor into the part instead of the prep.
What Pickling and Oiling Does to Hot Rolled Steel
The mill starts with hot rolled coil and runs it through an acid bath that strips off mill scale, rust, and surface stains. After a rinse and dry, a thin film of oil goes on to guard the bare steel against rust during storage and transit.
"Pickled" refers to the scale removal, and "oiled" refers to that protective film. The oil only protects for a short time, so plan to paint, coat, or put the material to use in a dry environment.
Clean, Scale-Free Steel That Welds and Forms Without the Extra Prep
With no scale at the joint, welders get steadier arcs and cleaner beads. Stamping and roll forming dies stay cleaner too, since there's no scale to flake off and build up on the tooling. The pickled surface takes paint after a standard degreasing step to remove the oil.
HRPO keeps the strength and lower cost of hot rolled steel, for jobs that don't need the tighter tolerances of cold rolled steel.
Pickled and Oiled Steel Coil for Stamping and Roll Forming Lines
Continuous stamping and roll forming lines run best on coil that stays consistent in gauge and surface from the first wrap to the last. As a pickled and oiled steel coil supplier, Curtis Steel stocks HRPO coil to ASTM A1011 and slits it in-house to the width your line runs.
- Specification: ASTM A1011, Grade CS-B, pickled and oiled
- Gauges: 1/4" through 14 GA
- Coil widths: 48" and 60"
- Slitting: our Braner 60" slitter handles HRPO up to .1875" thick, which covers 7 GA

Hot Rolled Oiled Steel Sheet Cut to Length for Welding and Fabrication
Welding shops and fabricators working in heavier gauges often need flat sheet at an exact length instead of a full coil. As a hot rolled oiled steel sheet supplier, we level and cut HRPO to your dimensions so it goes straight to the table or the brake.
- Leveling and cut-to-length: our Cincinnati line levels material up to 1/4" thick and 72" wide, in lengths up to 22 feet
- Shearing: 12-foot Cincinnati shear for clean, square edges
- Blanking: Red Bud 72" multi-cut blanking line holding tolerances of ±.005"
Where HRPO Steel Goes to Work
Manufacturers in construction, automotive, and agriculture use pickled and oiled steel for parts that need hot rolled strength and a clean surface to finish. Pipe and tube mills form it into welded pipe and structural tubing, and automotive suppliers stamp it into brackets and frame components.
Equipment builders use it for air compressor and filter housings, while storage manufacturers turn it into industrial racks and shelving supports.
Agricultural equipment makers build implements and frames from it, and packaging suppliers run it into package strapping.
