Aluminum profiles used in construction come in various types, each with specific applications. Common types include: 1. Extruded Profiles: These are the most common, formed by forcing aluminum through a die to create different shapes and sizes. 2. Structural Profiles: Used for structural integrity, such as beams and columns. 3. Decorative Profiles: For aesthetic purposes, like trims and moldings. 4. Industrial Profiles: Designed for specific industrial applications, like conveyor systems. 5. Window and Door Profiles: Specifically designed for window and door frames. 6. Heat Sink Profiles: Used for dissipating heat in electronic devices. 7. Railing Profiles: For constructing railings and balustrades. 8. Solar Profiles: Used in solar panel mounting systems. Each type has unique properties and is chosen based on the specific requirements of the construction project.
