First, the strength performance
1. It will strictly test the strength before leaving the factory.
2. Its intensity will be represented by a value, the general unit is N/m2. The performance is slightly better, the strength can reach 196l~2353N/m2, and the performance is relatively high, it can reach 2353~2764N/m2.

Second, water tightness

1. The watertightness is that the window is subjected to a certain number of water wave impacts accompanied by wind blowing. Watertight windows will withstand these tests and be presented intact.
2. The aluminum alloy doors and windows will pass the watertightness test, and there will be no water leakage in the room.

Third, the opening and closing force
Although it is relatively heavy compared to other doors and windows, it does not take much effort to open it.

Fourth, sound insulation

1. the sound insulation in the sound room is to detect its volume permeability.
2. The sound insulation effect is very good. After using it, you can lower the volume decibel.

Fifth, heat insulation

1. Thermally broken windows have a double-layer structure, so it will be more resistant to heat.
2. When a fire breaks out, its effect becomes apparent.

Sixth, nylon guide wheel durability

Pulling the pulleys many times, its pulleys will not be damaged, and it will withstand the test of the experiment.

Seventh, open and close the durability

The aluminum door locks are also very strong, and the lock remains intact after repeated tests.

I believe that after understanding so much performance, you must know how to choose aluminum alloy doors and windows, I hope the above performance will help you.
