Eight Advantages of Aluminum doors and Windows:

1. Lightweight and high strength

The aluminum alloy material is the thin wall composite section, easy to use, less weight, and the section has a higher flexibility strength, the doors and Windows using aluminium has small deformation, durable.

2. Good airtight performance

The sealing property is the important performance index of the door and window, compared to common wood door& window and steel door& window, the aluminium door&window has better performance of air tightness, water tightness and acoustic insulation.

3.Strong corrosion resistance, easy to use and maintenance

Aluminum doors & Windows do not rust, do not fade, and the surface does not need to be painted, and maintenance costs are low.

4: High strength, Good rigidity, Strong and Durable

5. High value

In building decoration engineering, especially for the high-rise buildings and high-grade decoration engineering, if from adornment effect and air conditioning operation and annual maintenance integrated balance, the use value of the aluminum doors and windows is better than other kinds.

6. Not faded, easy to maintain

The aluminum doors and Windows do not need to be painted, and the surface does not need to be repaired.

7. Open and close light and flexible, noiseless

8. Attractive appearance, a variety of colors available

The surface treatment technology of aluminum profile can satisfy different people with different aesthetic needs.

What are the indexes of material quality assessment for aluminium window & door?

1. Thickness: Aluminium door has 70 series and 90 series, (Serial digit 70 or 90 means the frame structure thickness is 70 or 90 mm), usually, 70 series sliding door applied in the residential interior. Aluminium window has 55 series, 60 series, 70 series and 90 series. Which series should be selected determined by the size of window aperture and wind pressure value in local.

2. Tensile Strength: the tensile strength should equal or greater than 157 N/mm², yield strength should equal or greater than 108 N/mm². A test method: when moderate bending the profiles, it should be able to return to the status after let go.

3. Colour scale: one piece of aluminium profile, the colour between two ends should be consistent if has an obvious chromatic aberration, unfavourable choose.

4. Flatness: Careful check the surface of aluminium profile, there should not be dents or bulging.

5. Glossiness: obvious opening bubble (white) and ash (black) on the surface of aluminium profile, (such as craze, burr, peeling etc) should be avoided to choose.

6. The degree of anodizing: the thickness of the anodized film should equal or greater than 10 μm. You can scratch the surface to see if the film can be erased.
