Pickling & Oiling Services – Clean, Rust-Free Steel Ready for Processing

At United Steel Industries, we offer pickling and oiling services designed to remove surface impurities like rust, scale, and oxidation from steel products, followed by a protective oil coating that prevents immediate re-rusting. Our HRPO (Hot Rolled Pickled and Oiled) solutions deliver clean, ready-to-use steel for fabrication, forming, and coating applications.
Whether you're sourcing HRPO coils, oiled steel plates, or looking to process your material before powder coating or galvanizing, we ensure your steel starts from the cleanest possible surface

What is Pickling and Oiling?

Pickling is the chemical treatment of steel using acid baths (typically hydrochloric acid or sulfuric acid) to remove mill scale, surface rust, and oxide layers that form during hot rolling or storage.

Oiling is the post-pickling step, where a light rust-preventive oil is applied to the steel surface to temporarily protect it from oxidation during storage, transport, or further processing.

This combination is referred to as HRPO (Hot Rolled Pickled and Oiled) steel, and it is widely used in applications where surface cleanliness and consistency are critical.

Benefits of Pickling & Oiling Steel

• Removes rust, mill scale, and oxide layers
• Improves surface appearance and uniformity
• Enhances adhesion for coatings like epoxy, paint, or galvanizing
• Prevents flash rusting through temporary oil protection
• Ensures accurate thickness tolerance and dimensional integrity
