What are the different sizes and shapes of aluminum profiles used for siding systems?

Aluminum profiles for siding systems come in a variety of sizes and shapes to accommodate different architectural styles and structural requirements. Common profiles include flat bars, channels, angles, and Z-profiles. Sizes can range from narrow trims of 10mm to wide panels of over 200mm in width, with thicknesses typically from 0.5mm to 3mm. Shapes are designed for specific functions, such as interlocking for a seamless appearance, or with grooves for attaching insulation. Custom profiles are also available for unique applications. These profiles are chosen based on the building's design, load-bearing needs, and aesthetic preferences.
