Question:

What type of aluminum alloy profile is used for high-rise balcony?

What type of aluminum alloy profile is used for high-rise balcony?

Answer:

The inner casement window is relatively safe, the window sash opens inside the room, and the window sash can not fall down, causing damage to pedestrians downstairs
High level words, with thick manganese magnesium aluminum alloy profiles, the main beam thickness of 3.3mm, is 110*65Secondary beam thickness in 3mm, 80*65Quite strong, and do not rust, the actual use of a long time, if necessary, can be Meikailong five floor of the East Hall GOTTIN see, professional production of sun room.
Aluminum alloy doors and windows in the material, materials, there are 6 main areas, you can refer to:1, thickness: aluminum alloy sliding door has 70 series, 90 series of two, residential interior aluminum sliding door with 70 series can be. Series numbers indicate the mm mm of the thickness of the door frame. The aluminium alloy sliding window has 55 series, 60 series, 70 series, 90 series four kinds. According to the window size and selected a series of local wind pressure value set. The aluminium alloy sliding window used as a closed balcony shall be no less than 70 series.2, chromaticity: the same aluminum alloy profile color should be consistent, such as color difference is obvious, that is not appropriate to buy.3, strength: tensile strength should reach 157 mm per square meter Newton, the yield strength to reach 108 Newton per square millimeter. When buying, you can use your hand to bend the profile properly. After you let go, you should be able to return to the original condition.4, flatness: check the aluminum alloy profile surface should be no dent or drum out.5, oxidation: oxide film thickness should reach 10 microns. When you buy it, you can light it on the surface of the section to see if the oxide film on it can be wiped off.6, gloss: aluminum alloy doors and windows, to avoid the surface has open bubbles (white dots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects profiles.
