Which one is better? Aluminum window or Steel wooden window?
Aluminum alloy doors and windows have the following advantages:
1) Light weight and high strength. The density is only one-third of that of steel.
2) Good sealing performance. The sealing performance directly affects the use function and energy consumption of doors and windows. Sealing performance includes four aspects: airtightness, water tightness, insulation, and sound insulation.
3) Good durability, easy to use and repair. Aluminum alloy doors and windows do not rust, fade, fall off, and require almost no maintenance. The service life of spare parts is extremely long.
4) The decorative effect is elegant. The surface of aluminum alloy doors and windows is coated with artificial oxide film and colored to form a composite film layer. This composite film is not only corrosion-resistant, wear-resistant, and has a certain degree of fire resistance, but also has extremely high glossiness. Aluminum alloy doors and windows, due to their light weight, precise and accurate processing and assembly, are easy to open and close with flexibility and no noise.
