HOT ROLLED STEEL (SHEET / COIL)

Hot rolled steel refers to a type of steel that is formed by rolling the steel at high temperatures, typically above the recrystallization temperature of the material. Hot rolled steel is produced through a process called hot rolling, which involves passing the steel through a series of rollers while it is heated.

Hot rolled steel is commonly available in two forms: sheets and coils.

Hot rolled steel sheets: Hot rolled steel sheets are flat, rectangular pieces of steel that are produced in a variety of thicknesses. They are often used in applications where a smooth surface finish is not critical, such as structural components, automotive frames, pipes, and construction materials.

Hot rolled steel coils: Hot rolled steel coils are continuous lengths of steel that are wound into coils. These coils are typically used in applications where the steel will be further processed, such as in the manufacturing of cold rolled steel, galvanized steel, or other steel products. Hot rolled steel coils are frequently used in industries like construction, automotive manufacturing, pipe and tube production, and appliance manufacturing.

The process of hot rolling provides several benefits to the steel. It allows for the shaping and forming of the steel at high temperatures, making it easier to achieve desired dimensions and shapes. Hot rolled steel also tends to have improved mechanical properties compared to cold rolled steel, such as higher tensile strength and ductility.

It's worth noting that hot rolled steel has a characteristic scale or oxide layer on its surface, known as mill scale. This scale is formed during the hot rolling process and may need to be removed through processes like pickling or abrasive cleaning, depending on the intended application of the steel.
