    Aluminum doors and windows with plastic doors and windows Wind strength and watertight performance comparison Plastic steel doors and windows due to the material strength and low rigidity, its wind fake panel for outdoor wall worth pressure and watertight performance than aluminum alloy doors and windows a lot lower. Moreover, since the plastic steel doors and windows lining steel is not connected to the corner of the profile into a complete framework of the system, window frames, fan corners and T-shaped joints of the plastic welding angle strength is relatively low.

    Second, the comparison of airtight performance Plastic steel doors and windows due to the box, the fan member is welded, so its air tightness should be slightly better than the aluminum alloy doors and windows with screws, but aluminum patio wood floors for sale alloy window and door profiles with higher dimensional accuracy, box, fan With more stringent. Third, the comparison of thermal insulation Broken Bridge aluminum alloy insulation strength and watertight compressive strength

    Comparison of steel doors and windows due to the material strength and low rigidity, its wind pressure and watertight performance is much lower than the aluminum alloy doors and windows. Moreover, since the plastic steel doors and windows lining steel is not connected to the corner of the profile into a complete framework of the system, window frames, fan corners balsa wood material properties and T-shaped joints of the plastic welding angle strength is relatively low.
