Precautions for choosing commercial windows and doors
Compared with steel-wood doors and windows, aluminum alloy doors and windows have the following advantages:
l) Light weight and high strength. The density is only 1/3 of steel.
2) Good airtight performance. The airtight performance directly affects the function of doors and windows and energy consumption. Sealing performance includes four aspects: air tightness, water tightness, heat insulation and sound insulation.
3) Good durability, easy to use and maintain. Aluminum alloy doors and windows are non-corrosive, non-fading, non-detaching, almost no maintenance, and extremely long service life of parts and components.
4) Elegant decoration effect. The surface of aluminum alloy doors and windows has an artificial oxide film and is colored to form a composite film. This composite film is not only corrosion-resistant, wear-resistant, has a certain fire resistance, and has a very high gloss. Aluminum alloy doors and windows are light in weight and precise and accurate in processing and assembly, so they can be opened and closed lightly and flexibly without noise.
It is not uncommon for aluminum alloy materials to experience deformation of doors and windows and immobility when pushing and pulling. Consumers should note the following points when purchasing:
Take a look at the material. There are six main aspects for reference in material materials:
⒈Thickness: There are 70 series and 90 series of aluminum alloy sliding doors, and 70 series is sufficient for aluminum alloy sliding doors inside the residence. The series number represents the number of millimeters in the thickness of the door frame. There are four types of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. The selection of the series should be based on the size of the window and the local wind pressure. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.
⒉Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, you can bend the profile moderately with your hands, and it should be able to recover after letting go.
⒊Chromaticity: The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase.
⒋Flatness: check the surface of the aluminum alloy profile, there should be no depression or bulging.
⒌Glossiness: Avoid buying profiles with open bubbles (white spots) and slag (black spots) on the surface of aluminum alloy doors and windows, as well as obvious defects such as cracks, burrs, and peeling.
⒍Oxidation degree: the thickness of the oxide film should reach 10 microns. When purchasing, you can swipe lightly on the surface of the profile to see if the oxide film on the surface can be wiped off
