Extruded Profiles: These are the most common, created by forcing aluminum through a die to achieve desired shapes. 2. Structural Profiles: Used for structural integrity in buildings, such as beams and columns. 3. Fa莽ade Profiles: Specifically designed for the exterior cladding of buildings. 4. Window and Door Profiles: For frame construction in windows and doors. 5. Fastening Profiles: Used for joining and fixing other aluminum components. 6. Special Profiles: Custom-made for unique applications. 7. Decorative Profiles: For aesthetic purposes, enhancing the appearance of structures. Each type has specific properties and is chosen based on the structural requirements and design considerations of the construction project.
