1.Differences in grades: Domestic aluminum alloy heat-dissipating windows and plastic-steel windows are suitable for different building consumer groups. Statistics show that plastic-steel windows are suitable for general low-rise residential buildings, and consumers of such grades often have products for this product. The quality requirements are not very high, and the high-performance heat-dissipating aluminum alloy window is suitable for all kinds of heights and various grades of buildings, and the quality and life performance can withstand the high standard test.
2.The difference in performance: the two energy-saving effects are similar; but due to the difference in materials, the plastic steel window is prone to deformation after a period of use, and the sealing performance is not as good as the high-performance aluminum alloy window.
3.The difference in life: due to the difference in material strength and elastic modulus and wear resistance, the service life of high-performance aluminum alloy windows is often greater than the service life of plastic steel windows.
4.The difference in price: Generally speaking, the price of high-performance aluminum alloy window is usually higher than the price of plastic-steel window. However, in the long run, the price of high-performance aluminum alloy windows is high, but the service life is long; while the plastic steel windows are cheaper, they have a shorter service life. Therefore, the overall price ratio is equivalent.
In summary, high-performance aluminum alloy windows are more competitive.
Fifth, the introduction of glass curtain wall
The name of the glass curtain wall is generally named after the width of the column (main beam, main keel), such as the width of the column is 155MM, that is, the 155 series. The glass curtain wall has a bright frame, full hidden, semi-hidden (horizontal and vertical, vertical and horizontal).
