How to identify the pros and cons of aluminum alloy doors and windows?

According to the survey, most owners do not know how to identify the quality of aluminum alloy doors and windows when purchasing aluminum alloy doors and windows. Let the editor help you understand. Aluminum alloy doors and windows have gained favor among consumers due to their unique advantages such as light weight, high strength, corrosion resistance, and the ability to be extruded into a variety of new complex cross-section materials. There is a tendency to gradually replace doors and windows made of plastic steel, wood and other materials.

In fact, identifying the quality of aluminum alloy doors and windows is nothing more than looking, touching, and listening. The best way to identify the quality of aluminum alloy doors and windows is as follows:

　1. Profile thickness
At present, the most commonly used aluminum profiles are 70 and 90 series aluminum profiles. The national standard wall thickness is more than 1.2mm, and the wall thickness of high-quality aluminum profiles is 1.2mm to 2.0mm.
　2. Degree of oxidation
How to check the oxidation degree of the profile? In fact, this is very simple. Just lightly scratch the surface of the profile when purchasing. After scratching, see if the oxide film on the surface can be wiped off. Warm reminder: Do not conduct this test on a sample window. You can conduct this test on the materials displayed by the merchant.
3. Profile color
Under normal circumstances, the cross-section color of high-quality aluminum profiles is silver-white and the texture is uniform. If you see obvious inconsistent color differences on the same profile, or the color is dark, it is not recommended to purchase. This may be Recycled aluminum or forged from scrap aluminum.
4． Profile surface smoothness
The surface of high-quality aluminum profiles is smooth and bright without dents or bulges. Generally, the surfaces of aluminum alloy doors and windows processed by large manufacturers are relatively smooth and bright, while the aluminum alloys processed by small workshops Due to machine or raw material problems, doors and windows may have slightly uneven surfaces
. Balcony windows made of such aluminum alloy profiles are easily oxidized and deformed in the later stage.
5． Profile Strength
When purchasing, you can bend the profile appropriately with your hands. If you bend the profile without any effort, it can be concluded that the strength of the aluminum profile is not up to standard. In addition, the strength of the profile is not the harder, the better. Aluminum has a certain degree of toughness and is not a hard material.
This characteristic can be used to forge it into different shapes., so owners need to look for the brand and observe carefully when purchasing.
6． Profile glossiness
Aluminum alloy doors and windows should avoid purchasing profiles with open bubbles and ash on the surface, as well as obvious defects such as cracks, burrs, and peeling. If the above phenomenon occurs, it can be concluded that it is secondary processing of recycled aluminum or scrap aluminum. Such materials are prone to cracking and oxidation due to uneven texture and messy alloy ratio.
7． Listen to the sound insulation sealing and look at the structural principles of the profile
When purchasing aluminum alloy doors and windows, you should listen to the sound insulation sealing and look at the structural principles to avoid being exploited by merchants because consumers do not understand the goods and do not understand the goods. Simplify or save Remove the sealing structure design and reduce the cost of aluminum materials. The top combination sealing method is used for the sealing process operation. The number of sealing layers is increased to reduce air convection and the use of automotive sealing strips can achieve better sealing performance.
