What are the different ways to join aluminum profiles together using fasteners?

There are several ways to join aluminum profiles together using fasteners: 1. Bolts and Nuts: Commonly used for strong and removable connections. 2. Rivets: Provide a permanent connection, suitable for high-stress applications. 3. Screws: Offer a secure and adjustable connection, often used in furniture and construction. 4. Pins: Used for alignment and positioning, often in lighter applications. 5. Adhesives: Can be used for a more aesthetically pleasing joint, though not as strong as mechanical fasteners. 6. Welding: Although not a fastener method, it is a common way to join aluminum profiles for a permanent and strong bond. Each method has its advantages and is chosen based on the specific requirements of the application, such as strength, permanence, and ease of assembly.
