After nearly 30 years of development, aluminum alloy doors and windows (windows and doors decoration effect map) has gradually replaced the plastic steel doors and windows, becoming the leading product of doors and windows. It is still far-fetched to say that aluminum alloy doors and windows are "high-end products." Because of its strong metal characteristics, there is still a large gap between the high-end furniture products and the preference of humans for “wood”. Aluminum-wood composite doors and windows gradually become the new darling of the high-end door and window market. Today, villas (villa decoration renderings), hotels (hotel decoration renderings), high-end club (club decoration renderings) and other occasions can see aluminum and wood composite doors and windows. So, how to buy high-end aluminum alloy(Aluminum foil for household 1235) doors and windows?

First, the product surface quality affects the appearance

The quality of doors and windows surface quality will directly affect the overall installation effect, so you should pay attention to the following aspects when checking the quality of doors and windows:

1. There should be no obvious damage to the decorative surface of doors and windows, and the protective film on the surface of doors and windows should not have scratches and scratches.

2. There should be no obvious color difference on the colored surface of adjacent components on the doors and windows.

3. There should be no aluminum chips, burrs, oil spots or other stains on the surface of the doors and windows; there should be no spillage of the adhesive at the assembly joints; there should not be too many nail holes exposed, affecting the appearance. In this regard, Li Dong also made a simple analysis of the Paiya doors and windows products, and sent Yamen doors and windows to the colors of rosewood and local tyrants. They were bright and bright, giving people a feeling of freshness and elegance. The main raw materials of the products were imported materials, and their formulas were exquisite. , Equipped with imported extruders and molds, the produced profiles are fine, uniform, and have a high degree of finish.
Second, the smaller the product size deviation, the better

Aluminum alloy doors(8011 aluminum foil on sale) and windows products will have a qualified range of dimensional deviation, the smallest size deviation is good. Outside the range, it is a non-qualified product. For example, a standard stipulates that the width and height of the notches of doors and windows shall be ≤2000mm, the permissible deviation range shall be ±1.0mm, and the verticality of the positive and lateral sides of the door/window frame (including picking materials) shall be ≤2000mm, and its allowable deviation The range is ≤2.0mm, and so on.

Third, the material needs to meet the five requirements

Aluminum alloy door and window products mainly have five requirements on the material used in materials:

1. Thickness: Aluminum alloy (Aluminum plate manufacturer china)sliding doors are available in 75 series, 88 series, 103 series, and 120 series (series numbers indicate the thickness of the door frame thickness in millimeters). The aluminum alloy sliding door in the house can use 88 series. The sliding window of aluminum alloy is selected from 50 series, 55 series, 70 series, 76 series, 118 series, 130 series, etc. It should be based on the size of the window hole and the local wind pressure value. Among them, aluminum alloy sliding windows used as closed balconies should not be smaller than the 55 series.

2. Strength: Tensile strength shall be 157 Newtons per square meter and the yield strength shall be 108 Newtons per square millimeter. When you purchase, you can use the hand to bend the profile moderately, and then you can restore the shape of the body after you loosen it.

3. Flatness: When inspecting the surface of the aluminum alloy profile, there should be no depression or bulging.

4. Gloss: aluminum alloy doors and windows to avoid the purchase of surface bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects in the profile.

5. Degree of oxidation: The thickness of the oxide film should reach 10 microns. When you purchase, you can lightly stroke the surface of the profile to see if the oxide film on the surface can be wiped off.

Fourth, aluminum alloy doors and windows are firmly connected components
