What are the different ways to join aluminum profiles together in building construction?

In building construction, aluminum profiles can be joined together using several methods: 1. Mechanical fastening, which includes bolts, screws, and rivets. 2. Welding, which permanently fuses the profiles together using heat. 3. Adhesive bonding, which uses specialized adhesives to bond the profiles. 4. Clipping or snap-fit connections, which use spring-loaded clips or interlocking parts. 5. Mortise and tenon joints, where one profile has a projection that fits into a hole in another. 6. Socket and pin connections, where a pin is inserted into a socket on the profiles. These methods can be used individually or in combination, depending on the specific requirements of the construction project.
