Cold rolled steel plate is the abbreviation for ordinary carbon structural steel cold-rolled plate, also known as cold-rolled plate. Cold rolled plate is a steel material that undergoes further processing at room temperature after hot rolling. Due to the formation of oxygen scale during the rolling process at room temperature, the surface smoothness, dimensional accuracy, and mechanical properties of the material can be improved. Compared with hot-rolled steel plates, cold-rolled steel plates have smoother surfaces, smaller tolerances, and higher strength.

Its applicable grades cover Q195-Q275 series, Japanese SPCC series, and German ST12 series standards, with surface treatment codes divided into matte (D) and glossy (B).

Cold rolling typically involves passing hot rolled steel through rollers at ambient temperature. The process reduces the thickness of the steel while improving its hardness and strength through strain hardening.

Cold rolled sheet metal is widely used in industries such as automotive manufacturing, home appliances, construction, furniture production, and precision engineering.

1. Excellent surface quality and appearance
2. Extremely high dimensional accuracy and consistency
3. Outstanding mechanical performance and strength
4. Good formability and processing performance

Automotive industry
More than 50% of the steel used in modern car bodies is Cold Rolled Sheet Metal. Exterior components such as car doors, engine hood, and trunk lid require extremely high surface quality, while structural components utilize their high strength and precise formability.

Home appliance manufacturing
Cold rolled sheets are widely used for the shells and internal structural components of household appliances such as refrigerators, washing machines, and air conditioners. Its good coating adhesion and beautiful surface directly enhance the appearance and texture of the product.

Architecture and Decoration
High quality metal roofs, wall panels, ceilings, and interior decorative strips are increasingly using pre painted cold-rolled steel plates, balancing aesthetics and durability.

Electronic products
Computer cases, server casings, electronic component shielding covers, etc. rely on the precise thickness and good electromagnetic shielding performance of cold-rolled sheets.

Q: Is cold rolled sheet metal more prone to rusting?

A: Due to its smooth, dense surface and absence of oxide scale, cold-rolled sheets usually have better corrosion resistance than hot-rolled sheets in the same environment, especially when combined with galvanizing or coating.

Q: Can cold-rolled plates be welded?

A: Sure, but please note. Due to its low carbon equivalent, cold-rolled plates usually have good weldability, but high-strength steel requires matching welding materials and processes.

Q: What is the difference between cold rolling and cold drawing?

A: Cold rolling is the processing of flat materials, while cold drawing usually refers to the forming of bars, wires, or tubes through mold drawing. Both are cold working, but the product shape and process are different.

We are an integrated industrial and trade company that can produce steel independently and reduce costs.

From raw materials to finished products, we control quality throughout the process to ensure that the products meet customer requirements.

The combination of production and sales confidentiality can respond to orders quickly and shorten delivery time.

One-stop service, from consultation to production, and finally to after-sales service, provides all-round support.

We are self-produced, reducing dependence on external price fluctuations. In the face of sudden price increases, we can still deliver quickly and on time.

For inventory steel, we can provide preferential prices.
