Hot-rolled sheet

Product Characteristics

● Good mechanical properties:

During the hot rolling process, the internal organization of the steel plate is improved, giving it high strength, toughness and good plasticity. This makes the hot rolled plate able to withstand large external forces and deformation, suitable for a variety of occasions with requirements on mechanical properties.

● Better surface quality:

Although the surface of hot rolled plate is not as smooth and flat as cold rolled plate, after modern advanced hot rolling process and finishing treatment, its surface quality can also meet the requirements of most applications. The surface oxidized skin is uniform, which is conducive to subsequent processing and coating treatment.

● Higher dimensional accuracy:

With the continuous development of hot rolling technology, the hot rolled sheet is now able to achieve higher dimensional accuracy, with the thickness tolerance controlled within a small range, and the width and length can also be produced according to the user's 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, with fast production speeds and the ability to produce on a large scale, resulting in high production efficiency. At the same time, since it does not require complex surface treatment and high-precision rolling control like cold rolling, the production cost is relatively low and has a high cost performance ratio.

Applications

● Construction

It is used to construct roofing panels, wall panels and purlins for industrial buildings such as factories and warehouses. Its high strength and good molding performance can meet the load bearing requirements of the building structure, and at the same time, it can be rolled into different cross-section shapes to meet the needs of building appearance and function.

In civil buildings, hot rolled sheet can be used to make stair treads, balcony railings and other components, providing reliable structural support and protection.

● Machinery Manufacturing

It is a commonly used material for manufacturing various mechanical equipment shells, supports and structural components.

● Automobile Industry

Hot rolled sheet is used in large quantities for the structural parts of automobile bodies, such as longitudinal beams, cross beams, inner door panels, and so on. The high strength of hot rolled plate can improve the collision resistance of the body to protect the safety of car occupants, while its good molding performance can meet the processing requirements of complex shapes of automobile body.

● Bridge Construction

It is one of the most important materials for bridge construction, and is used to make structural components such as main girders, bridge decks and piers. The high strength and corrosion resistance of hot rolled sheet can withstand the huge load and natural environment erosion in the process of using the bridge to ensure the long-term stable operation of the bridge.

For some large cross-sea bridges or bridges in special environments, hot rolled plates with special properties, such as weathering steel hot rolled plates, will be used to further improve the corrosion resistance and durability of the bridge.
