What are the different types of fasteners used to secure aluminum profiles in roofing systems?

In roofing systems, various types of fasteners are used to secure aluminum profiles, ensuring stability and longevity. Some common fasteners include: 1. Self-tapping screws, which thread directly into the aluminum without pre-drilling. 2. Rivets, which join two pieces of aluminum by compressing them together. 3. Nuts and bolts, used in conjunction with pre-drilled holes for a secure fit. 4. Clamps, which hold profiles together without penetrating the material. 5. Adhesives, used for bonding profiles in situations where mechanical fasteners are not suitable. 6. Clips and brackets, which can be used to attach profiles to other structural elements. Each type of fastener has its specific application and is chosen based on the design requirements and environmental conditions of the roofing system.
