Aluminum strips used for exterior applications come in various types, each serving specific purposes. These include: 1) Architectural Aluminum Strips, used for facades and building exteriors due to their durability and weather resistance. 2) Anodized Aluminum Strips, which offer enhanced corrosion resistance and a wide range of colors for aesthetic appeal. 3) Extruded Aluminum Strips, known for their strength and customizability, suitable for structural applications. 4) Embossed Aluminum Strips, which provide a textured surface for improved grip or decorative purposes. 5) Heat Insulating Aluminum Strips, used to reduce heat transfer in exterior applications. 6) Reflective Aluminum Strips, used for safety markings or to enhance visibility in outdoor settings. Each type is chosen based on the specific requirements of the project, such as strength, appearance, and environmental conditions.
