1. How is the aluminum alloy profile of doors and windows made?
It is a profile mainly composed of aluminum and some alloy elements to enhance strength and hardness. Aluminum alloy can be divided into aluminum silicon alloy, Aluminum copper alloy, aluminum magnesium, aluminum titanium alloy, aluminum zinc alloy and aluminum rare earth alloy according to chemical composition. Generally, the raw material alloy is aluminum ingot, and after aluminum ingot is melted into aluminum rod, it is extruded into doors and windows aluminum strip by heating. It has the characteristics of being not easy to oxidize and rust-resistant at normal temperature, but it will react with hydrogen. Although the process is relatively slow, however, in order to increase the service life, surface spraying anti-oxidation treatment is needed, and the service life of the treated aluminum alloy profiles is over 30 years.
2. What is Bridge-cutoff aluminum alloy profile? What are its advantages?
It is divided into two ends in the process of processing. In the middle, PA66 nylon heat insulation strip is used to connect the two ends into a whole to form a profile with heat insulation layer. The inside and outside are separated, and the inside and outside colors can be chosen arbitrarily. It can be made into two colors with beautiful appearance, good performance and energy saving effect.
3. What is the difference between ordinary aluminum alloy profiles and bridge-cutoff aluminum alloy profiles?
Ordinary aluminum profiles have a single color, the whole is a conductor, and the heat transfer and heat dissipation are relatively fast; The color of broken bridge aluminum profiles is diversified, and PA66 nylon heat insulation strips are used to connect both ends to form heat insulation layers. The temperature difference between inside and outside is different, reducing heat transfer, it plays the role of heat preservation and energy saving.
4. What is the standard wall thickness of aluminum alloy door and window profile?
Aluminum Alloy window profile the wall thickness of the main stress parts shall not be less than 1.4mm, and the thickness of the profile can be increased if the height reaches more than 20 layers; The wall thickness of the main stress parts of the heavy sliding door profile shall not be less than 2.0mm; this is a national standard that meets the requirements of wind pressure resistance. Single doors and windows can be thickened if they exceed 3-4 square meters, and large columns can be added to increase their physical strength.
5. What are the advantages of aluminum alloy doors and windows? How is the surface anti-corrosion?
Advantages of aluminum alloy: corrosion resistance, good weather resistance, no formaldehyde carcinogen aluminum alloy has surface treatment methods such as oxidation, electrophoresis, porcelain swimming, powder spraying, fluorine carbon, wood grain transfer printing, etc., forming oxidation resistance to aluminum alloy, anti-corrosion protective film improves the service life of aluminum alloy doors and windows.
6. What is system doors and windows? How did it come from?
System doors and windows originated from Europe. We have developed excellent system doors and windows suitable for China in combination with domestic national conditions and climate environment.
7. What is sliding doors and windows? What is flat doors and windows? What is the hanging window? What do you mean, open the inner window? What is fixed windows?
Sliding doors and windows: two doors and windows are in the same plane, and the doors and windows can be pushed and pulled horizontally to the left and right.
Flat open doors and windows: doors and windows open forward or backward. Opening doors and windows is not in the same plane, which will occupy a certain space and open indoors or outdoors in the wall.
Hanging window: the upper end is fixed, the opening fan is inclined to open, and the opening is below.
Inside opening and falling windows: European standard is adopted, which can be opened indoors and can be naturally ventilated. Doors and windows can also be opened when people are not at home. No matter how long the high-rise service time is, there is no need to worry about hitting downstairs.
Fixed doors and windows: doors and windows that cannot be opened.
8. Why should I choose to install doors and windows
broken bridge aluminum doors and windows?
Bridge-cutoff aluminum alloy doors and windows, the thermal insulation performance is superior, which conforms to the national policy of energy conservation and environmental protection. At the same time, different colors and styles can be achieved according to interior design and exterior wall design to meet the different needs of customers.
9. What are the main hardware accessories of sliding window? What are the main hardware accessories of casement window? What are the main hardware accessories for inner opening and inner pouring?
Sliding window main hardware accessories: pulley, Hook Lock, Crescent lock; Casement window main hardware accessories: linkage handle, dagger, hinge, lock point, lock box, hook and eye closure lock, Heaven and Earth lock, etc;
the main hardware accessories of the inner window are: linkage handle, link rod, linkage, etc.
10. What is LOW-E glass? What are its advantages?
LOW-E glass, also known as low-radiation heat reflection glass, is coated with a film on the surface of the glass to block ultraviolet rays outside. It can block outdoor high temperature in summer and keep indoor temperature in winter, which can protect human body.
11. What is hollow hundred-page glass? What material is leaf? What is the service life?
It is to install aluminum or stainless steel light blocking metal sheet in the hollow glass, which is controlled by magnetic force. It can be recycled for 20000 times for about 20 years. The advantage is that it can adjust the light at any time and is sanitary without cleaning.
12. What are the advantages of hollow glass, LOW-E glass and hollow hundred-page glass?
Hollow glass has good sound insulation and energy saving; LOW-E glass has energy saving and UV protection; Hollow hundred-page glass can prevent direct sunlight and increase privacy, which is convenient to use.
