With the advancement of science and technology, the replacement speed of building materials is also accelerating, and doors and windows have also developed from wood, plastic steel, to aluminum alloy. Aluminum alloy doors and windows are not only of good quality, light weight, good thermal insulation effect, but also come in various styles. Because aluminum alloy doors and windows are so popular among the public, some fake and shoddy products have also entered the market. We recommend several big brand aluminum alloy doors and windows for everyone.

2. Advantages of aluminum alloy materials

1. Light weight and high strength. Aluminum alloy materials are mostly hollow-core thin-walled composite sections, which are convenient to use and reduce weight. The sections have high bending strength, and the doors and windows made are durable and have little deformation.

2. Good sealing performance. Sealing performance is an important performance indicator of doors and windows. Compared with ordinary wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have better air tightness, water tightness and sound insulation performance. Aluminum alloy doors and windows themselves are slightly less airtight than flat doors and windows. Therefore, nylon tops are added to the structure of sliding doors and windows to enhance their airtight performance.

3. Corrosion-resistant, easy to use and maintain. Aluminum alloy doors and windows do not rust or fade, the surface does not need to be painted, and maintenance costs are low.

4. High strength, good stiffness, sturdy and durable.

5. High use value. In building decoration projects, for high-rise buildings and high-end decoration projects, if comprehensively weighed from the aspects of decoration effect, air-conditioning operation and long-term maintenance, the use value of aluminum alloy doors and windows is superior to other types of doors and windows.

6. Corrosion-resistant, easy to use and maintain. Aluminum alloy doors and windows do not need to be painted, they do not fade or fall off, and their surfaces do not require maintenance. Aluminum alloy doors and windows have high strength, good rigidity, durability, light and flexible opening and closing, and no noise.

3. How to choose aluminum alloy doors and windows

1. Light weight and bending resistance

Because the sections of door and window frames are mostly hollow thin-walled composite sections, this type of The cross-section facilitates use and reduces the weight of aluminum alloy profiles due to the hollow structure. Aluminum alloy doors and windows are about 50 times lighter than steel doors and windows.

2. Good sealing performance

Sealing performance is an important performance indicator of doors and windows. Compared with ordinary wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have better air tightness, water tightness and sound insulation performance. All relatively good.

3. Small deformation

Firstly, it is due to the good stiffness of the profile itself, and secondly, it is because of the cold connection used in its production process. Screws, bolts or aluminum nails are used to install the horizontal and vertical poles and hardware accessories. It uses angle aluminum or other types of connectors to connect the frame and fan poles into a whole.

4. Facade decoration

Firstly, the beautiful shape and large door and window area make the building facade simple and bright, and increase the contrast between virtual and real, giving a sense of layering; secondly, the color tone Beautiful, the door and window frame materials are processed through oxidation and coloring, and can have silvery white, golden yellow, bronze, bronze, yellow-black and other tones or colored patterns. The appearance is gorgeous and elegant, and there is no need to paint or perform surface repairs.

Through the above introduction to aluminum alloy doors and windows, I believe everyone has a certain understanding of aluminum alloy doors and windows. Nowadays, many furniture materials also use aluminum alloy. Everyone must keep their eyes open when purchasing to avoid buying fake and inferior products.
