Just look good?

When purchasing aluminum door and windows, some people think it's OK to have a good appearance. However, if they ignore the details, it is very likely to lead to the "medium look and useless" of the installed doors and windows in the future. Therefore, when purchasing aluminum alloy doors and windows, we should pay more attention to details. Observe whether the protective film on the surface of doors and windows is obviously damaged and free of stains, the construction coloring of adjacent parts shall be free of obvious color difference, and there shall be no overflow adhesive on the connecting components.

Hardware is not important?

Sometimes there is an illusion: hardware accessories are very insignificant and have a low position in the materials used for aluminum alloy doors and windows. In fact, hardware accessories are the heart of doors and windows. The system built by hardware accessories determines the performance of doors and windows. Hardware parts are made of materials suitable for themselves according to their different parts and functions. The quality of pulley depends on its outer wheel and bearing.

The thicker the profile, the better?

Many consumers feel that the thicker the aluminum alloy door and window profile, the better the quality of the door and window when it exceeds the national standard. First of all, this concept is wrong, in fact, it is not so; Secondly, the wall thickness of profile has a great impact on the price. The national standard for wall thickness of aluminum alloy doors and windows is to ensure the safety and performance of doors and windows. Too thick profiles can not guarantee the performance of doors and windows, and will waste resources.

The sign doesn't matter?

When purchasing aluminum alloy doors and windows, it should be noted that generally regular manufacturers have production licenses, and there will be obvious product marks on the doors and windows. We need to check the product logo, identify the content of the logo, and ask them to show their production license and other certificates. So as to avoid impersonation and imitation of doors and windows and prevent being deceived.
