90 aluminum alloy window sealing strip generally has a width of 0.2 mm. The sealing strip plays a waterproof, sealing and energy-saving role in plastic steel doors and windows, broken aluminum doors and windows and wooden doors and windows, and is sound-proof, dustproof, antifreeze and warm. It must have strong tensile strength, good elasticity, good temperature resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the cross-sectional structural size of the rubber strip must match the profile of the plastic steel door and window.

Characteristics of aluminum alloy window

The aluminum alloy material has light specific gravity and high strength, and the cross section of the door and window frame is a hollow thin-walled composite cross section, which is convenient to use. Because of the hollowness, the weight of the aluminum alloy profile is reduced. Aluminum alloy doors and windows are about 50% lighter than steel doors and windows. In the case of large cross-section size and light weight, its cross-section has high strength.
