What are the different types of fasteners used to fix aluminum profiles on building frames?

There are several types of fasteners used to fix aluminum profiles on building frames, including: 1. Bolts and nuts, which provide a strong and secure connection. 2. Rivets, which are permanent and can't be undone once installed. 3. Screws, which are versatile and can be used in various applications. 4. Clamps, which hold profiles together without penetrating the material. 5. Adhesives, which bond profiles together chemically. 6. Welding, which joins profiles together by melting and fusing them. 7. C-clips and T-nuts, which are specialized fasteners designed for use with aluminum extrusions. The choice of fastener depends on the specific requirements of the project, such as load-bearing capacity, aesthetic considerations, and ease of assembly or disassembly.
