Among aluminum alloy materials, it is recommended to use aluminum-magnesium alloy or aluminum-manganese alloy.
Aluminum-magnesium alloy also contains part of manganese. The biggest advantage of this material is its good oxidation resistance. At the same time, because of its manganese content, it has a certain strength and stiffness, making it the most ideal material for ceilings.
Aluminum-manganese alloy, the strength and stiffness of this material are slightly better than aluminum-magnesium alloy. But the oxidation resistance is slightly lower than that of aluminum-magnesium alloy. If both sides are protected, the shortcomings of its anti-oxidation ability being not as good as that of aluminum-magnesium alloy will basically be solved. ​
Aluminum alloy, which contains less manganese and magnesium. Therefore, its strength and stiffness are significantly lower than aluminum-magnesium alloy and aluminum-manganese alloy. Because it is soft and easy to process, as long as it reaches a certain thickness, it can basically meet the most basic flatness requirements of the ceiling. However, its oxidation resistance is obviously inferior to aluminum-magnesium alloy and aluminum-manganese alloy. And it is easy to deform during processing, transportation and installation. ​
Ordinary aluminum alloy, the mechanical properties of this material are not stable.
Beautiful and elegant punched ceilings are widely used in stadiums, shopping malls, hotels, airports, large conference venues and other places. Perforated mesh ceilings come in a variety of colors and hole types. If you have special requirements, we can professionally customize them for you.
