1. Broken bridge aluminum doors and windows have good thermal insulation. The inner and outer frames of the heat-insulating profile are softly combined, the frame adopts a rubber strip, and the double-jawed three-sealing form is tightly closed, and the airtight and watertight performance is excellent, and the heat preservation performance is superior; the window sash adopts an insulating glass structure, so that the window truly shows soundproofing. Insulation, heat preservation, excellent function, a large number of savings in mining and cooling costs, the heat transfer coefficient K value has been tested below 2.23 - 2.94w / 2K, energy saving effect is significant, several years of energy saving costs are enough to make up for the previous investment.
2. Waterproof function of broken aluminum doors and windows. The structure of the drainage system is designed by the principle of pressure balance, and the slope of the inclined design is stepped, and the drainage port is provided, the drainage is smooth, and the watertightness is good.
3. Broken aluminum doors and windows prevent condensation and frost formation. The broken aluminum profile of the bridge can realize the three-way sealing structure of the door and window, reasonably separate the water vapor cavity, successfully realize the pressure equalization of gas and water, significantly improve the watertightness and airtightness of the door and window, and achieve the effect of net brightening of the window.
4. Broken bridge aluminum door and window anti-mosquito screen design. Invisible screens, can be installed and used inside and outside, with anti-mosquito, flies, especially suitable for many mosquitoes in the north.
5. Broken bridge aluminum door and window anti-theft, anti-loose device. Equipped with a standard hardware lock to ensure the stability and safety of the window in use.
6. Broken bridge aluminum doors and windows to prevent noise and noise. The structure has been carefully designed, the seams are tight, and the test results show that the sound insulation of the air reaches 30--40db, which can ensure that the residents within 50 meters on both sides of the expressway are free from noise interference, and the adjacent downtown can also ensure the tranquility and warmth of the interior.
7. Broken aluminum doors and windows fireproof function. The aluminum alloy is made of metal, and the heat insulation strip is made of PA66+GF25 (commonly known as nylon insulation strip), which does not burn and has high temperature resistance.
8 broken aluminum doors and windows. Sand-proof, wind-resistant. The inner frame is made of hollow design, strong resistance to wind pressure deformation and good anti-vibration effect. It can be used in high-rise buildings and residential buildings. It can be designed with large-area window type and large lighting area. The airtightness of this window is better than any aluminum and plastic window, which can ensure the indoor window sill and floor of the area with large wind and sand without dust.
9. Broken bridge aluminum doors and windows have high strength and are maintenance-free. The aluminum structure of the broken bridge has high tensile and shear strength and resistance to thermal deformation. The durable and broken aluminum profile is not easily attacked by acid and alkali, and it is not easy to turn yellow and fade, and almost no maintenance is required.
10. Broken bridge aluminum doors and windows of various colors, very decorative. It can reach different colors of indoor and outdoor surfaces of doors and windows, satisfy customers' preference for color effect, aesthetic requirements of color space, and meet the individual design requirements of architects. The aluminum profile is streamlined and luxuriously styled.
11. Broken bridge aluminum doors and windows green building materials, circular economy. In the production process, the aluminum doors and windows of the broken bridge will not only produce harmful materials, but all materials can be recycled and recycled. It is a green building material and environmental protection product, which is in line with human sustainable development.
12. Broken bridge aluminum doors and windows open in many forms, comfortable and durable. There are swing type, inward tilt type, overhang type, push-pull type, swing type and inward tilt and compound type, etc., suitable for public buildings, residential quarters and municipal works; high-quality hardware accessories are durable, user-friendly design of operating handle, beautiful and comfortable, easy to open Flexible, each use action has been tested, the number of fatigue tests is more than tens of thousands of times, the sliding is easy and free, the sound is mature, the door and window processing technology is mature and perfect, and the high-precision program control machining center is used for production, and the quality is stable and guaranteed.
The outstanding advantages of heat-insulated bridge aluminum alloy doors and windows are high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life and good decorative effect. High-grade broken bridge profiles aluminum alloy doors and windows, is the first choice for high-end building windows.
Look at the materials: aluminum profiles used for high-quality aluminum alloy doors and windows, thickness, strength and oxide film, etc., should comply with the relevant national standards, the wall thickness of the inelastic assembly structure is above 1.4 mm, and the wall thickness of the inelastic assembly structure is 2.0 mm or more. The tensile strength reaches 157 Newtons per square meter, the yield strength is 108 Newtons per square millimeter, and the oxide film thickness should be 10 microns. If the above standards are not met, it is inferior aluminum alloy doors and windows, which cannot be used.
Look at processing: high-quality aluminum alloy doors and windows, fine processing, installation, stress, good sealing performance, switch freely. Inferior aluminum alloy doors and windows, blindly selected aluminum profiles and specifications, processing rough and shoddy, sawing instead of milling, not installed according to requirements, poor sealing performance, switch is not free, not only leaking wind and rain and glass burst phenomenon, but also encountered When it comes to strong winds and external forces, it is easy to scrape or knock down the push-pull parts or the glass, causing damage to people.
Look at the price: Under normal circumstances, high-quality aluminum alloy doors and windows due to high production costs, the price is about 30% higher than the inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have a tensile strength and yield strength that are much lower than the national standards and are not safe to use.
In addition, it is best to use the products of regular aluminum alloy doors and windows manufacturers, products that are not processed according to the standard are not easy to reach the standard.
