Definition Of Aluminum Alloy Doors

Doors constructed using extruded aluminum alloy profiles for frames, mullions, and sashes are known as aluminum alloy doors (or simply "aluminum doors"). This category encompasses doors that utilize aluminum alloy as the structural framework (bearing and transferring dead weight and other loads) and those featuring composite designs combining aluminum with wood or plastic. Aluminum alloy doors and windows represent the third generation of such products, following wooden and steel versions. my country introduced relevant technologies and equipment from Europe, the United States, and Japan in the mid-1980s; the industry's evolution has progressed through three stages: early single-profile aluminum doors and windows, colored aluminum doors and windows, and thermal-break aluminum alloy doors and windows (including aluminum-wood and aluminum-plastic composite varieties).
