2.5mm Fluorocarbon-Coated Bronze Textured Concave-Convex Aluminum Single Panel
The 2.5mm Fluorocarbon-Coated Antique Bronze Textured Concave-Convex Aluminum Veneer is a high-performance architectural decorative material. It is manufactured using 2.5mm-thick aluminum alloy sheets (typically 3003 series, H24 temper) as the base material, formed into 3D concave-convex textures through CNC bending, molding, or etching processes, and finished with advanced fluorocarbon spraying technology incorporating a special antique bronze formula for premium architectural applications.
Core Features & Advantages
Material Advantages
- Lightweight & High-Strength: Density of 2.7g/cm³, weighing only ~6.8kg/m², with tensile strength of 100-280N/mm². Reduces building load while ensuring structural stability.
- Superior Weather Resistance: Fluorocarbon coating resists UV radiation, acid rain, and salt spray corrosion, maintaining colorfastness for 20-25 years outdoors.
- Fire Safety: Non-combustible aluminum base meets global building fire safety standards.
- Eco-Friendly & Recyclable: 100% recyclable, aligning with green building initiatives.
Texture & Aesthetic Highlights
- 3D Layered Effect: Concave-convex textures create unique light and shadow interactions, enhancing the visual impact of building facades.
- Antique Bronze Charm: Warm brown tones with metallic luster replicate the elegance of real copper at only 1/5 the cost.
- Smooth Tactile Finish: Fluorocarbon coating offers a sleek, non-glare surface for comfortable visual experience.
Craftsmanship & Performance
- Multi-Coat Protection: Adopts "three-coat two-bake" process (primer + antique bronze topcoat + clear coat) to form a composite protective film ≥40μm thick.
- Extreme Environment Adaptability: Stable performance from -50℃ to 80℃ without deformation or discoloration.
- Self-Cleaning Function: Low surface tension of fluorocarbon coating prevents dirt accumulation; rainwater rinsing restores cleanliness.
Manufacturing Process Details
- Material Selection & Pre-Treatment: High-quality 3003/H24 aluminum alloy sheets undergo cleaning and chromate treatment to enhance coating adhesion.
- Concave-Convex Forming (Optional Methods):
- Die Stamping: Specialized molds create regular or irregular embossed textures.
- CNC Bending: Precision CNC equipment bends sheets to form 3D geometric shapes.
- Etching/Engraving: Chemical etching or mechanical engraving creates embossed effects with recessed patterns.
- Surface Treatment:
- Primer: Epoxy primer for enhanced adhesion.
- Antique Bronze Topcoat: Fluorocarbon paint with special metallic pigments to simulate copper color and texture.
- Clear Coat: High-weather-resistant transparent coating for improved gloss and protection.
- Curing: High-temperature baking at 230℃ ensures firm bonding between coating and base material.
