Q:What is PC aluminum alloy doors and windows
The surface is plated with a PC
Q:how can i repair this metal door?
just get some sheet metal and some rivets to patch the holes
Q:Plastic steel doors and windows and aluminum alloy doors and windows with what materials to fill, why?
After the installation of doors and windows should be filled with two foaming agent can play two roles 1 waterproof 2 shock (the main or shock friends because of a long time the foam will aging into a powder) the general project is foam again after the cement Cement and the external walls of paint and then hit a good weathering glue if you are a private decoration, then make a plastic after the bubble (glass glue can also be friends) can be the premise that the gap is not a big case of private and engineering Compared to the project after all, it is a hundred years
Q:Aluminum alloy doors and windows broken bridge and what is the difference between ordinary materials
Conventional aluminum alloy profiles because it is the whole body of aluminum alloy material, easy to heat the formation of thermal bridge effect The broken bridge aluminum alloy profile is based on the old aluminum alloy window in order to improve the performance of doors and windows insulation and the introduction of improved. Broken bridge aluminum alloy window principle is the use of PA66 nylon indoor and outdoor two-layer aluminum alloy is separated and closely connected into a whole, the connection can be divided into different ways to wear and type, with this profile doors and windows , Its superior heat insulation, completely solve the aluminum heat conduction fast, does not meet the energy requirements of the deadly problem, while taking some new form of cooperation with the form, completely solve the "aluminum alloy sliding window seal is not strict"
Q:Shuo steel doors and windows and aluminum doors and windows have any advantages and disadvantages
There are no advantages and appearance of the aluminum alloy, of course, the rural stalls which are very low prices of aluminum alloy when not to mention, the price of steel I do not understand, but the aluminum alloy is: Material 1.4mm, glass 6mm steel, then push and pull will go to 250 to 280, then open the words will go to more than 300, the price is basically the cost of regular processing production
Q:Bathroom with titanium alloy door or aluminum titanium door good?
First of all, I am ignorant of the decoration. I am the material of professional, only from the material analysis, if you do not consider the cost, should be titanium alloy, corrosion resistance is better than aluminum titanium alloy; the other hand, aluminum and titanium alloy should be cheaper, lighter, slightly less corrosion resistance The
Q:There are several kinds of aluminum alloy doors and windows
Aluminum alloy doors and windows material aluminum alloy doors and windows deformation, sliding and other phenomena are common. Consumers should note the following points: a look at the material. Material in the material on the main six can refer to: 1, the thickness: aluminum alloy sliding doors have 70 series, 90 series of two, residential aluminum alloy sliding door with 70 series can be. The number of series indicates the number of millimeters in the size of the frame thickness. Aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series four kinds. Series selection should be based on the size of the window hole and the local wind pressure value. The aluminum alloy sliding window used as a closed balcony shall be not less than 70 series. 2. Strength: Tensile strength should reach 157 Newton per square meter of millimeters, yield strength to reach 108 Newton per square millimeter. When buying, you can use the hand to bend the profile, after the release should be able to recover. 3. Chroma: the same aluminum alloy color should be consistent, such as color is obvious, that is not recommended. 4. Smoothness: check the aluminum alloy surface, should be no depression or bulging. 5. Gloss: aluminum doors and windows to avoid the purchase of the surface to open the bubble (white) and ash (black spots), as well as cracks, burrs, aluminum doors and other obvious defects in the profile. 6. Oxidation degree: oxide film thickness should reach 10 microns. When you buy, you can tap the surface of the profile to see if the oxide film on its surface can be wiped off.
Q:Silicon magnesium alloy door how much money a meter? Mainly kitchen door and toilet door
Silicon magnesium alloy door relative to the price of titanium magnesium alloy door is higher, because the silicon and magnesium alloy processing more difficult, high hardness, so the general manufacturers are reluctant to do this material, the cost is too high, only relatively large Formal manufacturers will do the silicon magnesium alloy door. For example, Hennessy European-style door, Dongguan door industry, Sao Paulo door industry, etc., you can check. The general price of the market in the 500 - 800 yuan a square meter, the specific but also engage in their own price. The price is determined by the thickness of the material, 1.2mm below the material do not consider, the glass must use the steel - unless the property of their own irresponsible.
Q:High-grade metal doors and windows ground
It is a very important measure to reduce the occurrence of fire, explosion, life hazard and equipotential in the space where lightning protection is needed. The equipotential is connected by means of a connecting wire or an overvoltage protector to the lightning protection device in the space requiring lightning protection, the metal frame of the building, the metal device, the outer conductor, the electrical and the telecommunication device. High-rise buildings must be reinforced concrete structure, steel structure of the building, should make full use of its metal parts to do lightning protection device, the metal as much as possible as a whole. Reinforced concrete components and steel structures in the steel should be connected to each other, the components must be connected between the electrical path, so that the entire building in the pressure. Therefore, metal curtain wall, aluminum alloy doors and windows design should be fully aware of the building's lightning protection devices and curtain walls, doors and windows of the lightning protection device outlet, and then determine a reasonable, economical, safe curtain wall, windows and doors mine design. Metal curtain wall, aluminum alloy doors and windows frame and other large metal objects, if the distance from the ground is equal to the ball radius and above, it should be connected with the lightning protection device, which is the first anti-side strike should take preventive measures. (The so-called ball radius is a sphere with a radius of Hr to scroll along the need to prevent lightning parts, when the ball only touched the flash device, or only touch the flash device and the ground without touching the need to protect the site, then the location To get the protection of the flash device).
Q:Aluminum doors and windows how to prevent wind?
If it is splicing gap, glue can be. If the sliding window to see if there is two cross-section of the wind fast, if not can consult a professional, with special wind fast.
