Hot rolled steel coil, also known as hot rolled strip, is a steel product that is continuously rolled by a hot mill. Hot rolling process refers to a process in which the billet is rolled several times at high temperature to reach the required size specifications. This process gives hot rolled steel coils unique physical and chemical properties, making them suitable for a variety of application scenarios.

Scope of application: In the field of construction, it is widely used in beams, columns, supporting structures of construction projects, as well as structural plates of floors and roofs, etc., all of which use hot-rolled steel coil as the main material.

In the automotive industry, hot-rolled steel coils are indispensable for the manufacture of body frames, chassis and other key structural components.

In the shipbuilding industry, because of its excellent weldability and mechanical properties, hot-rolled steel coils are the ideal choice for the manufacture of ship structures.

In pipe and tank manufacturing, hot-rolled steel coil is often used in the production of pipe systems and tanks that need to withstand high pressure due to its high pressure bearing capacity.

In the machinery manufacturing industry, hot rolled steel coil is also widely used in the manufacture of various mechanical equipment parts, such as gears, shafts, etc.

Advantages: Mechanical properties: Hot rolled steels exhibit excellent tensile strength and ductility through grain optimization.

Economy: Hot rolled steel coil is especially suitable for mass production because of its low cost.

Machinability: Hot rolled steel coils are easy to shear, bend and weld, and their surface roughness is perfect for processing needs.

Size and shape: A variety of sizes and shapes can be produced.

Welding ability: Hot rolled steel coil has excellent welding properties, easy to combine with a variety of materials.
