Aluminum strips are flat, thin pieces of aluminum, often used for applications requiring flexibility or where a thin cross-section is needed. They are typically used in packaging, electrical components, and construction. Aluminum profiles, on the other hand, are extruded shapes with a more complex cross-section, such as bars, tubes, angles, or channels. These profiles are used in structural applications, furniture, and various mechanical components where strength and specific shapes are required. The main difference lies in their form and application; strips are for flat, thin uses, while profiles are for more robust, structural uses.
