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, and high performance fault hot aluminium alloy window are various 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 5356 aluminum profile because of the material difference, plastic steel window application after a period of time is very easy to produce deformation, sealing performance is not as good as high performance aluminum alloy window.

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

        4. The distinction on price: say commonly, the price of window of window of 7003 aluminium profile of high performance aluminium alloy wants a few taller than the price of window of model steel normally. But from long-term consideration, high performance aluminum alloy window price although high, but the service life is long; And although model steel window price is cheaper, but use fixed number of year is short. Therefore, the overall price comparison is very.
