Self-cleaning Color Coated Steel
Wanzhi Steel’s self-cleaning color-coated steel is a new type of outdoor color-coated steel sheet. Its key feature is its self-cleaning properties. It can be cleaned outdoors directly with rainwater, requiring no maintenance. It is commonly used in industrial and urban areas with poor air quality.
Thickness: 0.2mm – 1.2mm
Width: 600mm – 1250mm
Surface Contact Angle: ≤60°
Stain Resistance: ≤1.0

Structural Mechanism
Hydrophilic Mechanism
The coating surface has extremely high surface energy, creating a strong affinity for water. When rainwater contacts the sheet, it doesn’t condense into droplets and roll off, but instead quickly spreads out as a uniform, ultra-thin film.
This film fully soaks and envelops dust and pollutant particles adhering to the surface, effectively reducing their adhesion to the coating. Subsequently, moderate rainfall washes away these pollutants along with the film, achieving highly effective surface cleaning.
Anti-fouling Mechanism
Highly Dense Topcoat Structure: The topcoat of self-cleaning color-coated steel sheet is specially formulated and processed to create an extremely dense, smooth microstructure. This structure significantly reduces surface porosity and irregularities, making it difficult for contaminants like oil and dust to penetrate and adhere firmly.
Self-Cleaning Color-Coated Steel Advantages
Outstanding Performance
Not only does it inherit the high decorative, corrosion-resistant, and weather-resistant qualities of ordinary color-coated steel, but it also features rainwater self-cleaning. Leveraging its dual “hydrophilic + anti-fouling” properties, rainwater washes away dirt, while the dense paint film blocks contaminants from penetrating.
Guaranteed Cost and Safety
No manual cleaning required, minimizing expensive manual cleaning and maintenance costs and eliminating the risks of working at height.
Applications of Self-Cleaning Color-Coated Steel
- Home Appliances: Widely used in air conditioner outdoor unit tops/covers, front covers/panels.
- Architectural: Suitable for building exteriors, industrial plant roofs, and large public facilities, where aesthetics and low maintenance are paramount.
