Aluminum alloy doors and windows from the processing of frame profiles, seals, supporting parts production, to doors and windows assembly test, can be organized in the factory, carry out a large number of industrial production, thus conducive to the standardization of door and window product design, product serialization and parts universalization, greatly improve the technical and economic effects of aluminum alloy doors and windows production.

Features of aluminum alloy doors and windows:

1. Light weight and high strength

The density of aluminum alloy is only 1/3 of steel, and it is a thin-walled, fasting extruded profile with light weight. The strength is close to ordinary low carbon steel, up to 30MPa or more, (high-performance window) casement aluminum alloy window wind pressure strength value is 300Pa~3500Pa.

2. Good sealing performance

The sealing performance of aluminum alloy doors and windows is obviously better than that of steel and wooden doors and windows, mainly because of its high processing accuracy, extremely tight assembly, and the use of rubber pressing strips and sealing materials with excellent performance.

3. Air tightness

The so-called air tightness refers to the size of the air permeability of aluminum alloy doors and windows under certain pressure difference conditions. The detection method of air tightness is usually in a special pressure test chamber, so that the front and back of the window form a pressure difference of more than 10MPa, and the ventilation volume per m2 area is determined within each h. For example, the airtightness of class A aluminum alloy casement window is 0.5m3/(m2 h)~1.0m3/ (m2 h), while class B (medium performance window) is l.0m3/(m2 h)~1.5m3/(m2 h).

4. Water tightness

Water tightness refers to the pulse average wind pressure value that aluminum alloy doors and windows can withstand without leaking rainwater. When testing, it is also in a special pressure test chamber, apply a sinusoidal pulse wind pressure with a period of 2s to the outside of the window, and at the same time spray 4L of artificial rain every min and m2 to the window to carry out continuous l0min wind and rain interplay test, and there should be no visible water leakage on the indoor side. For example, the watertightness of class A aluminum alloy casement window is 450Pa~500Pa, while Class C (low-performance window) is only 250Pa~350Pa.

5. Thermal insulation performance

The thermal insulation performance of aluminum alloy doors and windows is often divided into three levels according to the heat transfer resistance (m2 K/W), that is, I grade ≥0. 50; Class II≥0. 33; Щ level ≥0. 25。 Thermal insulation performance is also known as thermal insulation performance, steel windows, whether solid or fasting have no thermal insulation performance requirements.

6. Sound insulation performance

The sound insulation performance of aluminum alloy doors and windows is usually expressed by the amount of sound insulation (dB). It is in the sound test room to the window sound transmission loss test, when the sound frequency reaches a certain value, the sound transmission loss of aluminum alloy doors and windows tends to be constant. In this way, the sound insulation class curve can be detected. According to the different amount of sound insulation, the sound insulation performance is divided into five levels, and the aluminum alloy doors and windows should be above 25dB~40dB, that is, II~V level.

7. Good durability, easy to use and maintain

Aluminum alloy is durable and has no aging problems. The surface of doors and windows has a layer of extremely thin but very strong alumina film, so it does not rust, does not fade, does not fall off, almost does not need maintenance, spare parts service life is also extremely long, in addition, because of the light quality of aluminum alloy doors and windows, processing and assembly precision is high, so the opening and closing is light, sensitive, no noise.

8. Good decorative effect

Color decoration is crucial to the effect of architectural art, aluminum alloy doors and windows surface are anodized and electrolytic coloring treatment, the thickness of the oxide film in the thickness of the paint film above, the color is silver white, bronze, etc., aluminum alloy doors and windows its surface color choice is large, there are white, green and other colors and wood grain, granite and other surface colors.

9. Industrial production can be carried out

Aluminum alloy doors and windows from the processing of frame profiles, seals, supporting parts production, to doors and windows assembly test, can be organized in the factory, carry out a large number of industrial production, thus conducive to the standardization of door and window product design, product serialization and parts universalization, greatly improve the technical and economic effects of aluminum alloy doors and windows production.
