Aluminium Window Profiles: frame and fan structure window made of aluminum alloy construction aluminum profile. Doors and windows are generally named "model + function form", for example: 60 series open and inverted windows. The name of the door and window series is generally named after the width of the aluminum profile frame. Aluminum alloy doors and windows have outstanding performance compared with wooden decorative doors and windows and the gradually eliminated ordinary empty or solid-belt steel doors and windows. Its wind pressure strength performance, air permeability performance, rain water leakage performance, air sound insulation performance, thermal insulation Performance and opening and closing performance, etc., have reached the national standard requirements; and due to the characteristics of aluminum alloy materials, its processing, aluminum assembly and product installation can achieve higher precision, which is the energy-saving design and use of the building envelope structure Standard requirements such as safety provide important and necessary conditions.
