Color-coated coils, also known as pre-painted steel coils, come in various sizes to meet different application needs. The sizes of these coils can vary based on thickness, width, and length. Here are the typical sizes and their application scenarios:

Sizes of Color-Coated Coils

1. Thickness:
   • Range: 0.2 mm to 1.5 mm
   • Common Thicknesses:
     • 0.3 mm: Often used for lightweight applications like interior ceilings and partition panels.
     • 0.4 mm: Suitable for roofing sheets in residential and commercial buildings.
     • 0.5 mm: Common in both roofing and wall cladding applications due to its balance of strength and flexibility.
     • 0.6 mm: Used for more robust roofing and cladding, providing increased durability.
     • 0.8 mm: Typically used in industrial buildings where higher strength is required.
     • 1.0 mm to 1.2 mm: Applied in heavy-duty industrial applications and some automotive parts.
     • 1.5 mm: Used in applications requiring extra rigidity and strength, like some structural components and containers.
2. Width:
   • Range: 600 mm to 1500 mm
   • Common Widths:
     • 914 mm: Frequently used for specific appliance and automotive components.
     • 1000 mm: Standard width for various building materials and appliances.
     • 1200 mm: Common in larger panels and some automotive parts.
     • 1250 mm: Popular in the construction industry for roofing and cladding.
     • 1500 mm: Used in larger industrial applications and for wider roofing sheets.
3. Length:
   • Coils are typically supplied in lengths determined by the coil weight, which can vary:
     • Weight Range: 3 to 15 metric tons
     • Length Conversion: For example, a 0.5 mm thick coil weighing 5 metric tons can have a length of approximately 2000 meters.

Application Scenarios

1. Construction:
   • Roofing and Cladding: Color-coated coils are highly durable, weather-resistant, and available in various colors and finishes, making them ideal for aesthetically pleasing and long-lasting roofs and walls.
   • Sandwich Panels: These panels are used for thermal insulation and noise reduction in industrial buildings, cold storage facilities, and clean rooms, providing a strong and lightweight solution.
   • Ceilings and Partitions: Easy to install, these panels provide a smooth and attractive finish for interior spaces, often used in commercial buildings and offices.
2. Appliances:
   • Home Appliances: The coils are used for the outer casings of appliances like refrigerators, washing machines, and microwaves. The pre-painted surfaces offer excellent corrosion resistance and a premium look.
   • Office Equipment: Used for the manufacturing of office furniture, filing cabinets, and shelving units due to their sleek appearance and durability.
3. Automotive:
   • Vehicle Bodies: The high formability and corrosion resistance of color-coated coils make them suitable for exterior and interior parts of vehicles, including body panels, hoods, and doors.
   • Truck Trailers: Used in manufacturing durable and weather-resistant panels for truck trailers and other large vehicles.
4. Furniture:
   • Metal Furniture: Utilized for making stylish and durable metal furniture, including tables, chairs, and storage units. The pre-painted surfaces require less maintenance and provide a long-lasting finish.
5. Packaging:
   • Cans and Containers: Ideal for making food and beverage cans due to their non-reactive surfaces that prevent contamination and extend shelf life.
6. Other Industrial Uses:
   • Electrical Panels: Used for creating enclosures and panels for electrical systems, providing protection against environmental factors and electrical interference.
   • Signage: Employed in the production of high-quality signboards and advertising panels. The durability and vibrant colors make them suitable for outdoor and indoor use.

Summary

Color-coated coils offer significant advantages across various industries due to their versatility, durability, and aesthetic appeal. They are available in a range of sizes and specifications to meet the needs of construction, appliances, automotive, furniture, packaging, and other industrial applications. The pre-painted finish ensures long-term performance and reduces maintenance costs, making them a preferred choice for many manufacturers and builders.
