Aluminum profiles are metal materials. Aluminum add various metal elements to make various alloys, which have advantages that other alloy profiles cannot match. Aluminum alloys has light weight and high strength, and can be extruded into a variety of complex cross-section profiles meeting the requirements of door and window design for various new sections.

Arguably, one of the most popular and preferred aluminum grades for making window and door profiles. It is an alloy featuring highest level of corrosion resistance in the heat-treated aluminum alloy family.
