In construction, several types of fasteners are used to secure aluminum profiles. These include: 1. Bolts and Nuts: Commonly used for joining aluminum profiles, they provide a strong and secure connection. 2. Rivets: These are used for permanent connections and are ideal for load-bearing applications. 3. Screws: Self-tapping screws are often used for joining aluminum profiles without the need for pre-drilling. 4. Adhesives: Structural adhesives can be used for bonding aluminum profiles together, providing a strong and durable joint. 5. Clamps and Brackets: These are used to temporarily or permanently secure aluminum profiles in place. 6. Connectors and Brackets: Specifically designed for aluminum profiles, these connectors provide a secure and aesthetically pleasing joint. Each type of fastener has its own advantages and is chosen based on the specific requirements of the construction project.
