Stainless Steel Plate & Sheet

Cold Rolled 304 Stainless Steel Sheet: The superior choice of high-precision cold-rolled stainless steel plates and all-scenario metal solutions
In fields with high requirements for material accuracy, surface quality and corrosion resistance, Cold Rolled 304 Stainless Steel Sheet, with the dual advantages of "cold rolling process + high-quality 304 base material", has become a highly competitive product in the Stainless Steel family. Cold rolling process, through rolling processing at room temperature, not only keeps the thickness tolerance of the sheet within an extremely small range (usually up to ±0.02mm), ensuring excellent flatness and dimensional accuracy, but also endows it with a fine and smooth surface (with a roughness Ra value as low as below 0.4μm), meeting the high-end appearance requirements without additional complex treatment. The 304 stainless steel base material contains 18% chromium and 8% nickel, which can form a stable passivation film on the surface, effectively resisting erosion by the atmosphere, water, and weak acids and alkalis, and also has good ductility and toughness. Whether used for the casings of precision electronic components, the parts of medical devices, the panels of high-end household appliances, or the detailed parts of architectural decoration, Cold Rolled 304 Stainless Steel Sheet can have the characteristics of "high precision + high corrosion resistance + high appearance level", Redefine the application standards of Stainless Steel in precision manufacturing and high-end decoration scenarios, providing reliable and exquisite material support for projects. ​

When the scene demands lean towards "basic protection + economic practicality", Galvanized Steel demonstrates a high cost-performance advantage. It forms a zinc layer on the surface of Steel through the hot-dip galvanizing process, which can meet the anti-rust requirements of scenarios such as building light steel keels and common hardware parts, but its surface roughness and accuracy are far inferior to Cold Rolled 304 Stainless Steel Sheet. Galvalume Steel and Aluzinc Steel have achieved an upgrade in corrosion resistance. The corrosion resistance of the zinc-aluminum alloy coating is 2 to 5 times that of traditional galvanized steel, and it also has better high-temperature resistance. It is often used in large factory roofs, outdoor equipment casings and other scenarios. If used in combination in the same project - for example, in a high-end industrial park, the shells of precision equipment in the core workshop can use Cold Rolled 304 Stainless Steel sheets to ensure accuracy and corrosion resistance, while the roofs of ordinary warehouses in the park can choose Galvalume Steel. It can not only meet the functional requirements of different regions, but also achieve reasonable cost allocation, forming a scene adaptation of "precise corrosion resistance - basic weather resistance". ​

In the field that pursues "lightweight + easy processing", Aluminum Coil/Pipe/Plate becomes an ideal supplement. Aluminum coils can be made into flexible decorative panels, which are suitable for building curtain walls and advertising signs. Aluminum tubes, due to their light weight and thermal conductivity, are used in air conditioning refrigeration pipelines and drinking water transportation. Aluminum plates, with a density only one-third that of steel, can significantly reduce the self-weight of equipment and buildings, making them suitable for the interiors of rail transit and components of new energy vehicles. Compared with Cold Rolled 304 Stainless Steel Sheet, aluminium focuses more on "lightweight and ease of processing", but is slightly inferior in corrosion resistance and structural strength - for example, in the manufacturing of new energy vehicles, aluminium sheets can be used to reduce the weight of some body components. The protective casing of the battery pack requires Cold Rolled 304 Stainless Steel sheets to ensure corrosion resistance and structural stability, taking into account the balance of performance and weight. ​

For scenarios that emphasize "exterior decoration + basic protection", Prepainted Steel demonstrates unique value. It is based on Galvanized Steel or Galvalume Steel and coated with high-adhesion paint, featuring rich colors, UV resistance and scratch resistance. It is suitable for scenarios such as the exterior walls of integrated houses and the appearance panels of home appliances. Although Prepainted Steel can offer a variety of colors, it still cannot compare with Cold Rolled 304 Stainless Steel Sheet in terms of surface accuracy and corrosion resistance durability - for example, in high-end commercial buildings, For large-scale exterior wall decoration, Prepainted Steel can be used to create a colorful appearance. For the exquisite decorative panels at the entrance and the inner walls of the elevator car, Cold Rolled 304 Stainless Steel sheets are required with a fine surface and long-lasting corrosion resistance to enhance the overall high-end texture. ​

From the "high-precision precision application" of Cold Rolled 304 Stainless Steel Sheet to the basic protection of Galvanized Steel and the advanced weathering of Galvalume Steel and Aluzinc Steel, From the lightweight advantages of Aluminum Coil/Pipe/Plate to the color decoration empowerment of Prepainted Steel, we have built a full-scenario metal material matrix covering precision manufacturing, construction, home appliances, new energy and other fields. Whether you are an electronic enterprise seeking high-precision component materials, or a construction project requiring high-end decorative panels, or a manufacturing enterprise balancing cost and performance requirements, you can find precisely suitable solutions in our product system, with Cold Rolled 304 Stainless Steel Sheet as the core. By combining multiple metal materials, it helps the project achieve the operational goals of "precision compliance, reliable quality, and cost optimization". ​
