Hot rolled coil

Product Features

Good Mechanical Properties:

During the hot rolling process, the internal structure of the steel plate is improved, giving it high strength, toughness, and good plasticity. This allows hot-rolled steel plates to withstand greater external forces and deformation, making them suitable for various applications requiring mechanical performance.

Better Surface Quality:

Although the surface of hot-rolled plates is not as smooth and flat as cold-rolled plates, modern advanced hot rolling processes and finishing treatments enable the surface quality to meet the requirements of most applications. The surface oxide scale is uniform, which is beneficial for subsequent processing and coating.

Higher Dimensional Accuracy:

With the continuous development of hot rolling technology, current hot-rolled plates can achieve higher dimensional accuracy, with thickness tolerances controlled within a very small range. Width and length can also be produced according to user requirements to meet the dimensional needs of different projects.

High Production Efficiency and Low Cost:

The hot rolling process is carried out continuously at high temperatures, allowing fast production speeds and large-scale manufacturing, resulting in high production efficiency. At the same time, since it does not require complex surface treatments and high-precision rolling control like cold rolling, the production cost is relatively low, offering a high cost-performance ratio.

Product Applications

Building Exterior Walls

Used for roofing panels, wall panels, and purlins in industrial buildings such as factories and warehouses. Its high strength and good forming performance meet the load-bearing requirements of building structures, and it can be rolled into different cross-sectional shapes to satisfy architectural appearance and functional needs.

In civil buildings, hot-rolled plates can be used to make components such as stair treads and balcony railings, providing reliable structural support and protection.

Machinery Manufacturing

A common material for manufacturing various machinery equipment housings, brackets, and structural parts.

Automotive Industry

Hot-rolled plates are widely used in automotive body structural parts such as longitudinal beams, cross beams, and inner door panels. The high strength of hot-rolled plates can improve the vehicle's collision resistance, protecting occupants, while their good forming performance meets the processing requirements of complex-shaped bodies.

Bridge Construction

Hot-rolled plates are one of the most important materials in bridge construction, used to make main beams, bridge decks, and piers. The high strength and corrosion resistance of hot-rolled plates can withstand the heavy loads and environmental erosion during bridge use, ensuring long-term stable operation.

For some large sea-crossing bridges or bridges in special environments, hot-rolled plates with special properties, such as weathering steel hot-rolled plates, are used to further enhance the bridge's corrosion resistance and durability.
