Color-coated Aluminum Coils

Processing Technology of Color-Coated Aluminum Coils

Core Purpose of Surface Pretreatment (Simplified Version)

1. Cleaning: Removes oil, dust, and oxide scale from the aluminum coil surface, preventing paint blistering, delamination, and pinhole defects.

2. Passivation and Enhanced Resistance: Generates a dense conversion film, improving the corrosion resistance of the aluminum material itself and providing a strong "anchor point" for the coating.

3. Strong Adhesion and Stable Product: Optimizes the surface microstructure, resulting in stronger paint adhesion and less cracking during bending; simultaneously ensuring a uniform surface condition of the entire color-coated aluminum coil, improving finished product consistency and service life.

Main Applications

1. Building Roofing and Walls: Profiled aluminum sheets, factory exterior wall panels, roof cladding

2. Pipe Insulation: Thermal insulation panels for heating and gas pipelines

3. Decoration and Renovation: Interior ceilings, exterior curtain walls, outdoor decorative panels

4. Outdoor Projects: Billboards, bulletin boards, photovoltaic roofs, bus shelters

5. Industrial Materials: Roller shutters, equipment casings, cold storage insulation panels

6. Municipal Facilities: Overpass decoration, railing edging, landscaping panels
