1. Corrosion Resistance:
a. Anti-corrosion Coating Protection:
Color-coated steel sheets are coated with an anti-corrosion coating (such as polyester, silicon-modified polyester, or fluorocarbon), which effectively isolates the steel sheet from the outside environment, significantly improving corrosion resistance.
Regular steel sheets are prone to rust and require additional anti-corrosion treatment (such as painting or galvanizing), though the corrosion protection may not be as long-lasting as color-coated steel sheets.

b. Coating Enhances Protection:
Color-coated steel sheets are often coated with coatings such as aluminum-zinc or zinc-aluminum-magnesium. These coatings inherently offer excellent corrosion resistance, further extending the lifespan of the sheet.
Regular steel sheets typically lack such coatings or are simply galvanized, resulting in relatively weak corrosion resistance.

2. Aesthetics:
a. Rich Colors:
Color-coated steel sheets offer a wide variety of colors and can be customized with custom colors and textures, providing excellent decorative appeal.
Regular steel sheets have a monotonous color scheme and a more ordinary appearance, making them difficult to customize for personalized decorative needs.

b. Surface Texture
Color-coated steel sheets have a smooth, even surface coating, offering excellent gloss and texture, enhancing the overall aesthetics of a building.
Ordinary steel sheets may have surface defects such as scale and rust, which can affect their appearance.

3. Processability Advantages
a. Easy Processing
Color-coated steel sheets offer excellent processability, allowing for cutting, bending, and stamping, without damaging the coating during processing.
Ordinary steel sheets can also be processed, but may require additional anti-corrosion treatment after processing, and defects such as burrs and scratches may occur during processing.

b. Good Formability
Color-coated steel sheets can be formed into a variety of shapes and sizes to meet diverse architectural needs.
Ordinary steel sheets have relatively poor formability, making them difficult to process for complex shapes.

4. Economic Advantages
a. Low Long-Term Cost
Color-coated steel sheets may be slightly more expensive than ordinary steel sheets, but they offer lower costs over the long term. Their excellent corrosion resistance and aesthetics reduce the need for maintenance and replacement.
Ordinary steel sheets require regular anti-corrosion treatment and maintenance, increasing long-term costs.

b. High Construction Efficiency
Color-coated steel plates are lightweight and easy to install, significantly improving construction efficiency.
Ordinary steel plates are relatively heavy, and installation may require more manpower and time.
