3003 Decorative Aluminum Diamond Plate for Luxury Interior Wall Cladding & Architectural Ceilings – Anti-Fingerprint Brushed Finish (H14, 1-4mm)
The 3003 Aluminum Diamond Plate is a premium-grade, corrosion-resistant aluminum sheet with an embossed diamond pattern, optimized for luxury interior design, architectural cladding, and high-end commercial applications. With its 1.2% manganese content, it offers superior formability, strength, and aesthetic appeal compared to pure aluminum alloys (e.g., 1050/1100). The anti-fingerprint brushed finish ensures a sleek, low-maintenance surface ideal for modern interiors.
Key Features & Competitive Advantages✔ Anti-Fingerprint Brushed Finish – Oleophobic coating resists smudges (Ra ≤ 0.8μm)
