Our Doors Windows Profile Shapes are lightweight and strong. Because the section of the door and window frame is a hollow thin-wall composite section, this section is convenient to use and reduces the quality of the aluminum alloy profile due to the hollow. The aluminum alloy doors and windows are about 50% lighter than the steel doors and windows. In the case of larger section size and lighter weight, its section has higher bending rigidity.
And the airtight performance is good. Airtightness is an important performance index of doors and windows. Compared with ordinary wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have better air tightness, water tightness and sound insulation performance. For aluminum alloy doors and windows, the airtightness of sliding doors and windows is slightly worse than that of casement doors and windows.
