What are the different types of aluminum profiles used for wall frames?

Aluminum profiles for wall frames come in various types, each serving specific purposes. Common types include: 1) Structural profiles, which provide the main support and strength to the frame; 2) Cover profiles, used to conceal joints and fasteners, enhancing the aesthetic appeal; 3) Insulation profiles, designed to provide thermal insulation; 4) Glazing profiles, used to hold glass or other transparent materials in place; 5) Corner profiles, for joining two walls at a right angle; 6) Sealing profiles, to ensure weatherproofing and airtightness; and 7) Special profiles, tailored for unique architectural designs or specific functions. Each type is chosen based on the structural requirements, design aesthetics, and performance needs of the wall system.
