(1) Six advantages of aluminum alloy doors and windows
1. Strong plasticity
Aluminum alloy doors and windows are metal materials. Aluminum and various metal elements are cast into various alloys. It has the unparalleled advantages of other doors and windows. It has light weight and high strength. It can be extruded into various complex cross-sectional profiles used in various periods. Meet various new section material requirements of door and window designers.
2. Good airtight performance
The airtight performance directly affects the use function of doors and windows and energy consumption. Hermetic performance includes four aspects: water tightness, air tightness, heat insulation, and sound insulation.
3. Long service life
Due to its light weight, high density, and precise processing and assembly, aluminum alloy doors and windows are light and flexible to open and close, no noise, easy to use and maintain, corrosion resistance, small deformation, strong fire resistance, and long service life (50-100 years).
4. Environmental protection and energy saving
The new material H-UPVC can be used to form a partition space between the inner and outer profiles, so as to minimize the heat conduction of the aluminum alloy, and have good heat and sound insulation.
5. Excellent weather resistance
It is resistant to acid and alkali corrosion and free from air pollution, acid rain, and ozone. It is resistant to ultraviolet rays and maintains its inherent color and luster for a long time.
6. Elegant decorative effect
Paint surface treatment adopts powder coating process and wood grain heat transfer film. Powder coating is a spraying process, which has excellent resistance to fading, frosting, atmospheric oxygen pollution, acid rain and other corrosive properties, strong UV resistance, and can withstand harsh weather conditions. The wood grain heat transfer film technology originated in Italy. It uses heat transfer technology to transfer the wood grain to the surface of the metal plate to form a realistic wood grain on the surface of the product. The substrate does not need to be glued. Need to go through any treatment.
(2) Four major disadvantages of the advantages and disadvantages of aluminum alloy doors and windows
1. High thermal conductivity and poor sealing.
Especially aluminum sliding windows.
2. High energy-consuming industries.
The aluminum used is a high-energy-consuming product, and the aluminum ingot is produced through the electrolytic aluminum process. Each ton of aluminum ingot produced consumes 1,200 tons of electricity. Electrolytic aluminum is a restricted industry in my country.
3. General decoration
Metallic things are generally only used as embellishments. Aluminum alloy is disintegrated from the ore by electrolysis.
4. Not cost-effective
Although the cost is not high, but the plastic on the aluminum alloy will fall off after a long time, and it will not be water-proof in rain! After a long time, it is easy to wear and oxidize, so the appearance is not good!
