Aluminum extrusion profile with pre-drilled holes for curtain wall with black anodize

•Pre-Drilled Holes:ease of Installation: Pre-drilled holes ensure accurate alignment during assembly, 
•Black Anodized Surface Finish:Provides a sleek, uniform matte or semi-gloss black appearance, ideal for modern architectural designs.Corrosion Resistance: The anodizing process creates a hard, oxide layer that protects against moisture, UV radiation, and environmental pollutants.Anodized finishes are chemically bonded to the aluminum, ensuring long-term color retention without fading, peeling, or chipping (unlike painted finishes).
•Lightweight Strength:Aluminum extrusions offer high strength-to-weight ratios, minimizing structural 
•Fire Resistance:Aluminum is non-combustible (Class A fire rating), meeting stringent building safety standards.
•Recyclability:Aluminum is 100% recyclable, and anodizing is an eco-friendly process (no VOC emissions).
•Low Maintenance:The durable anodized surface requires minimal cleaning and no repainting, reducing lifecycle costs.
•Compliance & Standards:Meets international standards for curtain wall systems (e.g., ASTM, EN,Reach).
