What is Hot Rolled Steel Coil?
Hot-rolled coil (HRC) is a flat steel product produced by continuously rolling heated steel slabs through a hot rolling mill. It is typically supplied in coil form and is widely used in industries such as construction, machinery, automotive, shipbuilding, and pressure vessel manufacturing.
Hot-rolled steel is a fundamental material in the steel industry due to its low cost, good formability, and high production efficiency. It is suitable for structural applications that require high strength but not high surface accuracy. Further processing, such as cold rolling or surface treatment, is often required to improve dimensional accuracy or surface finish.

Detailed Classifications
Processing and Performance Characteristics of Hot-rolled Coil
Good formability: Suitable for bending, stamping, and drawing processes.
Excellent weldability: Compatible with various welding techniques and methods.
Moderate strength and good toughness: Capable of withstanding heavy loads.
Surface scale: May contain scale due to high-temperature oxidation, which is typically removed by pickling or further processing.
Coarse grains and uniform structure: Consistent and stable performance.
Economical and efficient: High production efficiency and low manufacturing costs.
