1. How is the aluminum alloy profile of doors and windows made? It is a profile mainly made of aluminum and added with some alloy elements to enhance strength and hardness. Aluminum alloy can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium

1. How are the aluminum alloy profiles of doors and windows made

is a profile mainly made of aluminum and added with some alloy elements to enhance strength and hardness. Aluminum alloys can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum titanium alloy,

aluminum zinc alloy and aluminum rare earth alloy according to their chemical composition. Generally, the raw material alloy is aluminum ingot, which is melted into aluminum rod and extruded into aluminum strips for doors and windows by heating. It is not easy to oxidize and rust at room temperature, but it will react with hydrogen. Although the process is relatively slow, in order to increase the service life, surface coating anti-oxidation treatment is required. Now the service life of the treated aluminum alloy profiles is more than 30 years

2. What is bridge broken aluminum alloy profile? What are its advantages

it is divided into two ends in the processing process, and the two ends are connected into a whole with PA66 nylon heat insulation strip in the middle to form a profile with heat insulation layer. The inside and outside are separated, and the inside and outside colors can be arbitrarily selected. It can be made into two colors, with beautiful appearance and good performance, forming an energy-saving effect

3. What is the difference between ordinary aluminum alloy profile and Bridge broken aluminum alloy profile

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 bridge cutoff aluminum profile is diversified. PA66 nylon heat insulation strip is used to connect both ends to form a heat insulation layer. The internal and external temperature differences are different, which reduces heat transfer and plays the role of heat preservation and energy conservation

4. What is the wall thickness standard of aluminum alloy door and window profiles

the wall thickness of the main stressed parts of the aluminum alloy window profile is not less than 1.4mm, and the high-rise reaches more than 20 floors. You can choose to increase the thickness of the profile; The wall thickness of the main stressed parts of the heavy sliding door profile is not less than 2.0mm

this is the national standard, which meets the requirements of wind pressure resistance. Single doors and windows with an area of more than 3-4 square meters can be thickened, and columns can be added to increase their physical strength if they are too large

5. What are the advantages of aluminum alloy doors and windows? How is the surface protected against corrosion

advantages of aluminum alloy: corrosion resistance, good weather resistance, no formaldehyde carcinogens

aluminum alloy has surface treatment methods such as oxidation, electrophoresis, porcelain swimming, powder spraying, fluorocarbon, wood grain transfer, etc., which can form an anti-oxidation and anti-corrosion protective film for aluminum alloy and improve the service life of aluminum alloy doors and windows

6. What is system door and window? How did it come from

system doors and windows come from Europe. We develop excellent system doors and windows suitable for China in combination with domestic national conditions and climatic environment

7. What is sliding door and window? What is a casement door and window? What is the hanging window? What is "inside open and inside inverted window"? What is a fixed window

sliding doors and windows: refers to the doors and windows that can be pushed and pulled horizontally to the left and right when the two doors and windows are in the same plane

side hung doors and windows: doors and windows are opened forward or backward, and the opening fans are not in the same plane, which will occupy a certain space. Doors and windows that open indoors or outdoors in the wall

upper hung window: the upper end is fixed, the opening fan is tilted and opened, and the opening is below

internal opening and internal inverted window: European standard is adopted. It can be opened indoors for natural ventilation. Doors and windows can also be opened when people are not at home. No matter how long the high-rise is used, there is no need to worry about hitting the downstairs

fixed doors and windows: doors and windows that cannot be opened. 8. Why choose broken bridge aluminum doors and windows when installing doors and windows

bridge cutoff aluminum alloy doors and windows have excellent thermal insulation performance, which is in line with the national policy of energy conservation and environmental protection. At the same time, different colors and styles can be achieved according to the 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 windows? What are the main hardware accessories for inside opening and inside pouring

main hardware accessories of sliding window: pulley, hook lock, crescent lock; Main hardware accessories of casement window: linkage handle, sliding brace, hinge, lock point, lock box, back buckle lock, heaven and earth lock, etc; The main hardware accessories of the inner opening and inverted window: linkage handle, linkage, 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 maintain indoor temperature in winter, which plays a protective role for the human body

11. What is hollow hundred leaf glass? What is the material of the page? What is the service life

is to install aluminum or stainless steel light blocking metal sheets inside the insulating glass, which is controlled by magnetic force. It can be recycled for 20000 times for about 20 years. Its advantage is that it can adjust the light at any time, which is hygienic and does not need to be cleaned

12. What are the advantages of insulating glass, Low-E glass and insulating hundred leaf glass

insulating glass has good sound insulation and energy saving; Low-E glass can save energy and prevent ultraviolet radiation; Hollow hundred leaf glass prevents direct sunlight and increases privacy, which is convenient to use
