HOT ROLLED STEEL
Carbon hot rolled coil steel (often abbreviated as hot rolled carbon steel coil or HRC) is a widely used flat steel product made primarily from carbon steel that undergoes a hot rolling process. It begins as thick steel slabs that are heated to very high temperatures (over 1,700°F) and then continuously passed through a series of rolling mills to reduce their thickness into long strips. These strips are cooled and wound into large, tightly wound coils for easier storage, transportation, and further processing. Hot rolled carbon steel coils typically have a rough, slightly scaled surface that is often covered with a bluish-black iron oxide layer, known as mill scale, formed during cooling, giving the steel its characteristic dark, oxidized appearance compared to smoother cold rolled steel.

HOT ROLLED PICKLED & OILED STEEL
The Hot Roll Pickling and Oiling process (commonly referred to as HRPO or P&O) is a post–hot rolling surface treatment applied to carbon hot rolled coil steel to remove mill scale, the iron oxide layer that forms during heating and cooling, and to protect the cleaned surface from corrosion. During hot rolling, steel is heated to approximately 1,700–2,300°F, and exposure to air causes oxidation, forming a thin but tough layer of mill scale. This dark, rough, and brittle scale can flake off, interfere with forming and bending, create defects in downstream processes such as cold rolling, and reduce paint or coating adhesion. Through the pickling process, the scale is chemically removed, and a light oil coating is applied to help prevent rust. The result is HRPO steel with a clean, scale-free metallic appearance, improved formability and weldability.

COLD ROLLED STEEL
Cold rolling is a metalworking process that reduces the thickness of hot rolled steel at or near room temperature, below the steel’s recrystallization temperature; unlike hot rolling which occurs at much higher temperatures. The process usually begins with hot rolled pickled and oiled (HRPO) coils to ensure the mill scale has been removed and the surface is clean before further reduction. As the steel passes through rollers at lower temperatures, it undergoes work hardening (strain hardening), which increases its strength and hardness while also producing a smoother surface finish, tighter dimensional tolerances, and improved flatness compared to hot rolled steel.
