Aluminum alloy door and window quality standard aluminum alloy doors and windows quality how to identify

Aluminum alloy can play a very good decorative effect. Because of its excellent performance, it stands out in many doors and windows materials, and has become the focus of modern home improvement. And aluminum alloy doors and windows have many advantages, light weight, high strength and good durability. The following small series for everyone to introduce the quality standards of aluminum alloy doors and windows and how to identify the quality of aluminum alloy doors and windows.

Aluminum alloy doors and windows quality standards

1, a look at the use of materials

The materials, thickness, strength and oxide film used in high-quality aluminum alloy doors and windows are in compliance with relevant national standards. Its tensile strength can reach 157 Newton per square meter, and the yield strength should reach 108 Newton per square millimeter. The thickness of oxide film should be It reaches 10 microns. If it fails to meet the above criteria, inferior aluminum alloy doors and windows cannot be used.

2, second look processing

High quality aluminum alloy doors and windows, good sealing performance, fine processing, easy to switch. The poor quality aluminum alloy doors and windows, processing and shoddy, saw cutting instead of milling, not according to the requirements of the installation, poor sealing performance, the switch is not comfortable, not only leakage of air leakage, but also the glass burst phenomenon, encountered strong winds and external forces will easily push and pull part Or glass scraping, hurting others.

3, three to see the price

High-quality aluminum alloy doors and windows have high production costs, so the prices are relatively high. Some aluminum alloy doors and windows made of only 0.6-0.8 mm thick aluminum have lower tensile strength and yield strength than those of the relevant national standards and are not safe to use. Therefore, it is best to use the products of regular aluminum alloy door and window manufacturers.

How to distinguish the quality of aluminum alloy doors and windows

1, a good aluminum alloy should be white in the pan-blue

Good aluminum alloy profiles should be multi-cavity with reasonable design and thick walls. In addition, look at the color, high-quality aluminum alloy doors and windows of C profile formulations added anti-aging agent and anti-ultraviolet and line additives, the appearance of white color in the pan-blue, touch smoother, can be maintained in the outdoor environment, no aging, no discoloration No deformation.

2, good profile glass flat slide smooth

Aluminum alloy doors and windows of the glass to be flat, no water lines and plastic profiles are not in direct contact, there is a sealing layer close to the gap. In the case of double glazing, there should be no dust or water vapour in the interlayer; the aluminum sliding rails in the lower part of the window frame of the sliding window should be easy to replace. In general, the double pulley is better than the single pulley.

3, good accessories pulley high seal strength does not slot

High-quality aluminum alloy doors and windows hardware accessories are made of metal, the strength is very high. Some inferior aluminum alloy doors and windows are made of plastic materials, which will cause adverse effects on the quality of doors and windows and the service life. In addition, accessories, such as sealing strips should be flat, no curling, no groove, no odor.

The above is about the quality standards of aluminum alloy doors and windows and the quality of aluminum alloy doors and windows how to identify the relevant knowledge, after reading it is not more understanding of this area!

Exterior Use High Speed Roller Doors

Exterior use High Speed Doors are designed for outside doors of factory and warehouse, which will face wind pressure from outside. Such exterior rapid doors need be reinforced to withstand big wind.

Normally, if such doors are made from PVC fabric, it must be supported with metal wind bars at the middle. And the high speed door can be aluminum material, to get biggest wind resistance.
