# Hot-Rolled Coil (HRC)

A hot-rolled coil (HRC), also referred to as a "hot-rolled steel strip" or "hot-rolled steel band," is a product made by heating a slab of steel in a reheating furnace, continuously rolling it into a long strip with roughing and finishing mills, and then winding it into a coil for easy transport.

A typical hot coil has a thickness of 1.2 to 25 mm. Because it is rolled while heat is applied, its surface is covered with a black film known in the industry as "scale," which is an oxidized layer. It is used in a wide range of fields as a material for construction and industrial machinery.

There are many types of steel sheets, including [cold-rolled steel](https://www.o2oh.com/glossary/cold-rolled-steel-crs) sheets and plated steel sheets.
