Aluminum alloy materials often appear door and window deformation, push and pull immovable and other phenomena. Consumers should note the following points when choosing and purchasing:
Look at the material. There are six main aspects to be consulted in material use:
1. Thickness: Aluminum alloy sliding doors have 70 series and 90 series. Aluminum alloy sliding doors in residential buildings can be used in 70 series. Series denotes the number of millimetres in the thickness construction dimension of the door frame. There are 55 series, 60 series, 70 series and 90 series of aluminum alloy push-pull windows. Series selection should be based on the size of the window and local wind pressure. Aluminum alloy push-pull windows used as closed balconies should be no less than 70 series.
Strength: Tensile strength should reach 157 Newtons per square meter millimeter and yield strength 108 Newtons per square millimeter. When choosing and purchasing, the profile can be moderately bent by hand, and can be restored after loosening hands.
3. Chromaticity: The same aluminium alloy profile should have the same color. If the color difference is obvious, it is not suitable to buy.
4. Flatness: Check the surface of aluminium alloy profiles, there should be no depression or bulge.
5. Gloss: Aluminum alloy doors and windows to avoid the selection of open surface bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects of the profile.
6. Degree of oxidation: The thickness of oxide film should reach 10 microns. When selecting and purchasing, you can scratch the profile surface lightly to see if the oxide film can erase the specifications of aluminum alloy doors and windows: there are five kinds of aluminum alloy doors and windows: push-pull aluminum alloy doors and windows, push-pull aluminum alloy windows, flat-open aluminum alloy doors, flat-open aluminum alloy windows and aluminum alloy floor spring doors. There are national architectural standard design drawings. Each kind of doors and windows is divided into basic doors and windows and combined doors and windows. The basic doors and windows are composed of frames, fans, glass, hardware accessories, sealing materials, etc. Composite doors and windows are composed of more than two basic doors and windows and other forms of windows or windows with diaphragm.
Each kind of door and window is divided into several series according to the thickness of the door and window frame. For example, the push-pull aluminium alloy door with 90 mm thickness of the door frame is called the 90 series push-pull aluminium alloy door.
There are 70 series and 90 series of aluminum alloy sliding doors. The basic height of the doors is 2100, 2400, 2700 and 3000 mm. The width of the basic doors is 1500, 1800, 2100, 2700, 3000, 3300 and 3600 mm.
Push-pull aluminum alloy window has 55 series, 60 series, 70 series, 90 series, 90 I series. The basic window height is 900, 1200, 1400, 1500, 1800, 2100 mm; the basic window width is 1200, 1500, 1800, 2100, 2400, 2700, 3000 mm.
Aluminum alloy flat door has 50 series, 55 series, 70 series. The height of the basic portal is 2100, 2400 and 2700 mm, and the width of the basic portal is 800, 900, 1200, 1500 and 1800 mm.
There are 40 series, 50 series and 70 series of flat aluminium alloy windows. The basic window height is 600, 900, 1200, 1400, 1500, 1800, 2100 mm; the basic window width is 600, 900, 1200, 1500, 1800, 2100 mm.
Aluminum alloy floor spring door has 70 series, 100 series. The height of the basic portal is 2100, 2400, 2700, 3000 and 3300 mm, and the width of the basic portal is 900, 1000, 1500, 1800, 2400, 3000, 3300 and 3600 mm. The color of anodic oxide film on the surface of aluminium alloy profile is silver white and bronze. Ordinary plate can be used for glass varieties
