Aluminum extruded profiles are alloy materials with aluminum as the main component. Under the strong pressure of the extruder, profiles with specific cross-sectional shapes and sizes are extruded through a die. The following are its applications in the field of doors and windows:
Material and performance advantages
Lightweight and high-strength: The density of aluminum is about 2.7g/cm³, which is much lower than many common metals. This makes aluminum extruded profiles light in weight and more convenient and labor-saving during transportation and installation. At the same time, its strength should not be underestimated. By reasonably adding alloy elements (such as magnesium, silicon, etc.) and optimizing processing technology (such as heat treatment, cold processing, etc.), high strength can be obtained, which can meet the mechanical performance requirements of doors and windows in different use environments.
Corrosion resistance: Aluminum easily reacts with oxygen in the air, forming a dense aluminum oxide film on the surface. This oxide film can prevent the internal aluminum from being further oxidized, making it have good corrosion resistance. During the long-term use of doors and windows, even if exposed to natural environments such as wind and rain, aluminum extruded profiles are not easy to rust and corrode, and have a long service life.
Good thermal conductivity and electrical conductivity: Aluminum has a high thermal conductivity coefficient, so in door and window applications with insulation requirements, the thermal insulation technology can be used to effectively block the transfer of heat and improve the insulation performance of doors and windows. In addition, the conductivity of aluminum also enables it to better realize signal transmission and electrical connection in some special door and window applications, such as doors and windows with electronic intelligent control functions. Easy processing and recyclability: Aluminum extruded profiles have good plasticity and processability, and can be made into door and window components of various shapes and sizes through cutting, drilling, bending, stamping and other processing methods to meet different architectural styles and design requirements. Moreover, aluminum has high recycling value, and the energy consumption of recycling is only about 5% of the energy consumption of original aluminum production, which is conducive to saving resources and protecting the environment.
Specific application in doors and windows
Production of window frames and door frames: Aluminum extruded profiles can be extruded into different cross-sectional shapes according to the design requirements of doors and windows, such as common square, rectangular, circular, etc., and then assembled into window frames and door frames through cutting, splicing and other processes. Its precise size and stable shape can ensure the installation accuracy and overall stability of doors and windows, and provide reliable support for the normal use of doors and windows.
Glass inlay: Aluminum extruded profiles have good machining properties, and various grooves, card slots and other structures for inlaying glass can be processed on its surface to facilitate the installation and fixation of glass. At the same time, by using sealing materials such as sealing strips and aluminum profiles, a good sealing effect can be achieved, and the airtightness, watertightness and thermal insulation performance of doors and windows can be improved.
Connection of hardware accessories: Hardware accessories of doors and windows (such as hinges, handles, locks, etc.) usually need to be firmly connected to the window frame or door frame. Aluminum extruded profiles can be easily installed with various hardware accessories through drilling, tapping and other processing methods, and can ensure the strength and stability of the connection, making the opening and closing of doors and windows smoother, safer and more reliable.
Application of thermal insulation bridge technology: In order to improve the thermal insulation performance of doors and windows, thermal insulation bridge aluminum extruded profiles are often used. This profile is to insert a thermal insulation strip in the middle of the aluminum profile, dividing the aluminum profile into two parts, inside and outside, thereby effectively blocking the conduction of heat. On the basis of maintaining the advantages of aluminum profiles, thermal insulation bridge aluminum doors and windows greatly improve the thermal insulation effect of doors and windows, reduce the energy consumption of buildings, and meet the requirements of modern building energy conservation.
Appearance decoration: The surface of aluminum extruded profiles can be processed by anodizing, electrophoretic coating, powder spraying and other methods to obtain various colors and textures, such as imitation wood grain, imitation stone grain, etc., which can meet the needs of different architectural styles and personalized decoration, so that doors and windows are not only practical, but also highly decorative, improving the overall beauty of the building.
