door and window shopping skills for everyone, come and have a good look.
First look at the thickness
in order to prevent the purchase of substandard aluminum alloy doors and windows, measure its thickness when purchasing. The thickness of aluminum alloy material is above 1.2mm, generally, manufacturers of aluminum alloy doors and windows will install national standards to implement them, but in case of emergency, the thickness problem cannot be ignored when purchasing.
Sealing performance
look at the sealing performance of aluminium windows households, especially aluminium windows of double-layer glass. If the sealing performance is poor, fog will be generated between double-layer glass, which will affect the use effect.
View composite film quality
there is a layer of composite film on the glass of aluminum alloy window. When purchasing, you should check the composite film on the glass. The Composite film can improve the wear resistance and corrosion resistance of the glass, and can also effectively improve the brightness of the glass.
Contrast Processing details
A good craft item looks at the welding part. If the welding part is rough and uneven, there are even burrs, etc., these are inferior aluminum alloy doors and windows.
Buy brand
like home decoration aluminum alloy doors and windows, it is recommended to buy some big brands, manufacturers with good reputation and environmental protection standards will be more guaranteed.
Qualified size deviation range
high-end aluminum alloy doors and windows products will have a qualified size deviation range, and it is better to minimize the size deviation. If it is out of range, it is a non-qualified product. For example, there is a standard regulation that the width and height of the slot of the door and window frame should be ≤ 2000mm, and the allowable deviation range is ± 1.0mm; The positive, the verticality of the side is ≤ 2000mm, and the allowable deviation range is ≤ 2.0mm, etc.
