Aluminum Expanded Mesh Can Undergo Various Surface Treatments To Enhance Its Appearance, Durability, And Performance In Different Environments. Here Are Some Common Surface Treatments:
1. Anodizing
Process: Electrochemical oxidation that forms a protective oxide layer.
Benefits: Improves corrosion resistance, wear resistance, and allows for color dyeing (e.g., black, gold, red).
Applications: Architectural, decorative, and industrial uses.
2. Powder Coating
Process: Electrostatic application of dry powder, then cured under heat.
Benefits: Durable, UV-resistant, available in various colors and textures (matte, glossy, textured).
Applications: Outdoor furniture, façades, fencing.
3. PVDF Coating (Polyvinylidene Fluoride)
Process: High-performance fluoropolymer coating applied via spray or roller.
Benefits: Excellent weather resistance, color retention, and chemical resistance.
Applications: High-end architectural projects in harsh environments.
Polishing/Brushing
Process: Mechanical polishing to create a smooth, reflective, or brushed finish.
Benefits: Enhances aesthetics (mirror or satin look).
Applications: Decorative panels, interior design.
Chemical Conversion Coating (Chromate/Phosphate)
Process: Chemical bath application to form a corrosion-resistant layer.
Benefits: Improves paint adhesion and corrosion resistance.
Applications: Aerospace, military, and automotive industries.
Choosing The Right Treatment
Outdoor Use: Anodizing, PVDF, or powder coating for weather resistance.
Decorative: Polishing, anodizing, or lacquering for aesthetics.
Industrial: Mill finish or chemical conversion for cost efficiency.
Each treatment affects the mesh's cost, lifespan, and suitability-select based on environmental exposure and functional requirements.
