1. What are the specifications of aluminum alloy door and window profiles?
1, aluminum profile specifications generally mainly include 40, 45, 50, 55, 60, 65, 70, 80, 90, 100mm and other series specifications, among which the aluminum profile specification series is small and the size series used for aluminum doors is large. Moreover, the specifications of general aluminum alloy profiles are divided into cross-sectional shape, wall thickness and length. Except curtain wall series and other building aluminum profiles, there is no clear model distinction for industrial aluminum profiles, and most manufacturers process them according to customers' actual drawings. According to the processing technology of aluminum profile after extrusion, it can be basically divided into oxidation, electrophoresis, electrostatic powder spraying and fluorocarbon spraying, that is to say, the coating methods are different.
Second, the purchase skills of aluminum alloy doors and windows
1. When purchasing aluminum alloy doors and windows, the first thing you need to do is to see if there is a manufacturer with a formal product logo or production license, and indicate the product logo in the obvious part of its aluminum alloy products, including: manufacturer's name or trademark, product name, product model or logo, production date or number. There should be obvious words and signs such as "moistureproof", "handle with care" and "upward" on the packing box.
2. When buying aluminum alloy doors and windows, we should also look at the surface quality, because the installation will directly affect the decorative effect of the whole wall. Therefore, there should be no obvious damage to the decorative surfaces of aluminum alloy doors and windows, no obvious color difference, aluminium scrap, burr, oil stain or other stains on the colored surfaces of adjacent components, and no overflowing adhesive at the assembly joints.
3. Doors and windows have high processing quality, fine processing, exquisite installation and good sealing performance. How to open and close them freely needs attention when purchasing. Inferior aluminum alloy doors and windows blindly adopt aluminum profile series and specifications, and the processing is shoddy. Saw instead of milling, not installed as required. Poor sealing performance, uncomfortable switch, not only air leakage and rain leakage, but also glass cracking. When encountering strong wind and external force, it is easy to scratch or touch the push-pull part or glass, damaging things and hurting people.
It is also important to pay attention to the materials used in doors and windows. The thickness, strength and oxide film of aluminum profiles used for aluminum alloy doors and windows should meet the relevant national standards, and the wall thickness of the main stress bar of aluminum alloy windows should be 1. Above 4 mm, the wall thickness of the main stress bar of aluminum alloy door should be 2. 0 mm or more, the tensile strength should reach 157 Newton per square millimeter, the yield strength should reach 108 Newton per square millimeter, and the thickness of oxide film should reach 10 micron. If you can't meet the above standards, it is inferior aluminum alloy doors and windows and can't be used.
5, door and window glass is very important, when buying, you need to check whether it is flat and firm, and there can be no looseness. Single-layer glass should not be in direct contact with the profile, the inner and outer surfaces of double-layer glass should be clean, there should be no dust and moisture in the glass interlayer, and the gasket should not be inclined.
6. When buying aluminum alloy doors and windows, you must choose the right doors and windows according to the size of the room. Size, according to the use requirements, choose the appropriate type of doors and windows. Secondly, according to the use parts of doors and windows (such as interior doors and exterior doors), determine the various performance requirements of doors and windows. For example, windows and track doors have certain requirements for heat insulation, sound insulation, water tightness and air tightness. Finally, the user chooses the appropriate color of the door and window frame according to his own preferences and the collocation with other decorative pieces.
The above are the specifications of aluminum alloy doors and windows profiles introduced by Bian Xiao and the skills of purchasing aluminum alloy doors and windows. If you want to know the specifications of aluminum alloy doors and windows, you can refer to Bian Xiao's introduction, hoping to help everyone.
