China is the world's largest producer of aluminum profiles, offering high-quality, customizable extrusions for construction, industrial, and furniture applications. Key manufacturers, concentrated in hubs like Guangdong and Shandong, utilize alloys such as 6063, 6061, and 7075. Common finishes include anodized, powder-coated, and wood grain, with competitive pricing, typically ranging from $2.50 to $5.50 per kg, depending on specifications.
Key Features and Capabilities:
- Customization: Extensive OEM/ODM services for custom shapes, including angles, channels, tubes, and complex structural profiles.
- Surface Treatments: Anodizing (5-12 microns), powder coating (40-120 microns), electrophoresis, and wood grain finishes.
- Alloy Grades: Primarily 6000 series (6063/6061) for architectural and structural uses, ensuring strength, corrosion resistance, and high machinability.
- Compliance & Quality: Many manufacturers hold ISO 9001:2015, ISO 14001, and RoHS certifications.
Common Applications:
- Architectural: Window and door frames, curtain walls, and building facades.
- Industrial: Machine frames, assembly lines, conveyor systems, and automotive parts.
- Modular/DIY: T-slot profiles for automation and aluminum furniture.
When sourcing, verifying the alloy grade and surface treatment is crucial to meet specific environmental and mechanical requirements.
