1. How to identify the quality of aluminium alloy profiles?
From the appearance, the good aluminium alloy profile oxidation coloring film surface light, the appearance of beautiful, pure color, no discoloration, no scratches, the quality of a little weight, smooth lines, a silver light, and not hair; Corrosion, rigidity and durability.
2. What are the types of aluminum alloy windows, windows and windows?
Aluminium alloy doors and windows and windows and windows are different in material, but in the form of structure and use. The types of aluminum alloy and steel doors and windows are mainly based on the opening mode. The following are the following:
1. Door: there are only two kinds of sliding doors. The so-called ping is the axis of the hinge, and the rotation opens. The traditional wooden door windows are all flat. The open door is divided into two kinds of open doors and open doors.
2. Window: in addition to pulling the window (including around the window, outside the window), there is a kind of hanging window. Different ways of opening are different.
（1）Pull the window: The advantages are simple, beautiful, large windows, large glass, wide range of vision, high lighting, easy to clean glass, flexible, reliable, long life, open in a plane, use less space. Installation screen is convenient.
（2）Flat window: The advantage is that the opening face is big, the ventilation is good, the seal is good, the sound insulation, the insulation, the Kang performance is excellent.
（3）On the top of the window: This is the first appearance of an aluminum alloy, steel window. It is a new form developed on the basis of a flat window. It has two types of opening, both open and open from the top. When the window closes, the upper part of the window can open a gap of about 10 cm, which means that the window can be opened from above, and the open part hangs in the air. By tying the chain to the edge of the window frame, it is called the hanging window. The advantage of it is that it can be ventilated and safe, because there is a chain, the window can only open more than 10 centimeters of the seam, from the outside the hand can’t come in, especially suitable for the use of home. Recently, this kind of function has not only limited to the open window, the push-and-pull window can also be hung open.
3. How to choose aluminum alloy doors and windows?
1. See if the material is up to standard. High-quality aluminum alloy doors and windows used in the thickness, intensity and oxide film should be in line with the relevant standards of national space.
2. See if the appearance is fine. High-quality aluminum alloy doors and windows processing fine, from the appearance of the surface of the protective film, no scratches, scratches, there is no aluminum, burr, oil spots or other stains, The adjacent component coloring has no obvious color difference, the assembly connection does not spill the adhesive, the door and window frame size deviation is also very small. Inferior aluminum alloy doors and windows processing, cutting, cutting and processing, the workmanship is not fine.
3. See if it is convenient and safe to use. The high-quality aluminum alloy doors and windows are installed, the component connections are strong, the connection part of the use of corrosion-resistant filling materials, doors and windows closed, windows and doors and doors and doors are not obvious gaps, pressure There is no obvious gap in the joint; Doors and windows open flexible, no block, rebound and distortion of the phenomenon. The hardware of high-end doors and windows are made of metal, its internal strength, appearance, good use or not directly affect the performance of windows and windows.
4. See if the manufacturer is regular. The self-employed and small factories of aluminum alloy doors and windows are used. They sometimes use provocative properties. The structure of windows and windows is sometimes unreasonable, and the safety risks are greater, and it is easy to use. Therefore, it is best to choose a regular manufacturer of products. Regular manufacturers have production licenses, the obvious parts of the product are marked, such as factory name, trademark, product name, model, factory date, etc.
