1. Differences in grades: China break hot window of aluminium alloy profile and model steel window is suitable in different engineering construction of purchase crowd, statistics show that the model steel window is generally low layer housing, usually customers for the goods of this type of class device quality regulation is not very high, while u aluminum high-performance break hot aluminium alloy window, relative height, apply to all kinds of grade of engineering construction, And the quality, service life performance has stood standardized hone.

        2. The difference in performance: the actual effect of environmental protection and energy saving is similar; But aluminum alloy window profile because of the material difference, plastic steel window application after a period of time is very easy to produce deformation, sealing performance than high-performance aluminum alloy window.

        3. The difference on service life: because the strength of material and elastic die and wear resistance performance distinction is bigger, make the service life of high-performance aluminum alloy window exceeds the service life of model steel window normally.

        4. The distinction on price: say commonly, the price of window of high performance aluminium alloy window wants a few taller than the price of window of model steel normally.
