What is Aluminum C Profile?
Aluminum C Profile is a type of extruded aluminum section shaped like the letter “C.” It is primarily produced from 6000 series alloys, such as 6063 or 6061, which provide a balance of strength, corrosion resistance, and lightweight performance. This profile is widely used in construction, framing, decoration, ventilation systems, and structural support. Typical wall thickness ranges from 1.0 mm to 3.0 mm, with dimensions customizable to project needs. It is available in various tempers, such as T5 and T6, offering good machinability and stable mechanical properties. Common surface treatments include anodizing, powder coating, polishing, brushing, and electrophoresis, which improve durability and enhance appearance. Aluminum C Profiles comply with standards like GB/T5237, ASTM B221, and EN specifications, ensuring consistent quality. With versatility in function and design, they are ideal for modern architectural and industrial applications.
