1.2mm Thickness 3003 Series Color Coated Aluminum Sheets for Exterior Building Applications

Product Overview

Core Product Specifications

Key Advantages for Exterior Building Use

• 3003 Alloy Superiority: Aluminum-manganese composition enhances corrosion resistance by 35% vs. pure aluminum, perfectly suited for exterior walls exposed to rain, dew, and humidity. Excellent formability supports complex exterior designs like curved cladding.

Key Advantages 

• 1.2mm Thickness Advantage: 20% thicker than 1.0mm sheets, providing stronger impact resistance (withstands 5J impact without deformation) and wind load capacity, ideal for high-rise building exteriors.
• Exterior-Grade Coating Protection: PVDF coating ensures 95% color retention after 20 years; polyester coating resists UV yellowing. Both options repel acid rain and salt spray, suitable for coastal and industrial zones.
• Energy-Saving Performance: Light-colored coatings reflect 70%+ sunlight, reducing building interior temperature by 3-5℃ in summer. Meets energy efficiency standards for green buildings.
• Low Maintenance & Longevity: Smooth coating prevents dust and dirt accumulation; annual water cleaning is sufficient. 20+ year service life reduces exterior renovation frequency and costs.

Applicable Exterior Building Scenarios

• Residential Exteriors: Villa exterior walls, high-rise apartment cladding, balcony railings, entrance decorative panels
• Commercial Exteriors: Shopping mall facade cladding, office building exterior walls, hotel decorative surfaces, retail storefronts
