1.Can cold-rolled coils be used in hardware products?
Typical metal products: hinges, door lock panels, drawer slides, tool clips, and various brackets.
Cold-rolled steel sheets have high thickness precision and a smooth surface, resulting in hardware parts that are aesthetically pleasing, dimensionally accurate, and slide smoothly.
2.Are cold-rolled coils used for appliance housings and structural components?
Refrigerator side panels/panels, washing machine outer shell, microwave oven inner liner, air conditioner vent panels
Cold-rolled steel sheets have a smooth and clean surface, making them easy to treat with spraying, baking paint, and other surface treatments, thus meeting the dual requirements of home appliances for appearance and corrosion resistance.
3.Are cold-rolled coils used in office and furniture production?
Filing cabinets, office desk cable trays, side panels/doors of steel furniture, bookshelf shelves
The strength and rigidity of cold-rolled steel sheets are sufficient to support the structure, while their good flatness ensures the aesthetics and uniform gaps after furniture assembly.
4.Can cold-rolled coils be used in lighting and electrical applications?
LED lighting fixture housings, light panels, distribution box enclosures, cable trays, electrical control cabinets
Cold-rolled steel sheets are easy to stamp and bend, and can be processed into various complex shapes. They also have good electrical conductivity and electromagnetic shielding potential.
5.What are the core advantages and points to note?
High dimensional accuracy: The thickness tolerance of cold-rolled steel sheets can be controlled within a very small range (e.g., ±0.02mm), ensuring high dimensional consistency in stamped products, making them ideal for mass production.
Good surface quality: Cold-rolled steel sheets have a smooth surface, free of iron oxide scale, allowing for direct electroplating, spraying, and baking paint processes to create attractive products.
Good mechanical properties: Hardened by cold rolling, their strength is higher than that of ordinary hot-rolled steel sheets, meeting the strength requirements of structural components while maintaining good workability.
Wide thickness range: Cold-rolled coils typically range in thickness from 0.1mm to 4mm, enabling the processing of both extremely thin electronic components and structural parts of a certain thickness.
