　　1. Wind pressure resistance and water tightness: Due to the low material strength and rigidity of plastic steel windows, although they are reinforced with steel, their wind pressure resistance and water tightness are about two levels lower than aluminum windows. Moreover, since the steel lining of plastic steel windows is not connected into a complete frame system at the inner corners of the profiles, the strength of the plastic welded corners at the four corners and the T-shaped joints of the window frame and sash is relatively low. According to the analysis of 425 batches of plastic steel window three-performance samples submitted by Shanghai enterprises at the end of 1998, it was seriously pointed out that "plastic windows should be used cautiously in high-rise buildings."

　　2. Air tightness: Since the frame and sash components of plastic steel windows are welded, their air tightness should be slightly better than that of screw-connected aluminum alloy windows. However, the aluminum window profiles have higher dimensional accuracy, and the frame and sash fit more tightly, so the two are still at the same level.

　　3. Heat insulation performance: The heat insulation performance of aluminum windows is not as good as that of plastic steel windows, but the ratio of the overall heat transfer coefficient of the two windows is only 1.36 times (single-layer window) and 1.44 times (single-frame double-glazed window).

　　4. Light transmission performance: The light transmission performance of plastic steel windows is worse than that of aluminum windows, and its frame single component has a shading surface.

　　Titanium alloy aluminum alloy doors and windows also belong to aluminum alloy doors and windows, but some titanium components are added inside. Most titanium metal is used in the aviation industry. Industrial aluminum profiles have the characteristics of light weight, high hardness, and corrosion resistance, so titanium alloy doors and windows have the characteristics of not being easily deformed, light weight, corrosion resistance, and oxidation resistance.

　　Jiangsu Kuna New Energy Co., Ltd., established on July 24, 2018, is located on the west side of Provincial Highway 326 in Xiangshui County Industrial Economic Zone, Yancheng City, Jiangsu Province. It has a registered capital of 166.67 million yuan, covers an area of 345 mu, and has a building area of 200,000 square meters. The total planned investment of the project is 600 million yuan. The first phase will start the construction of 75,000 square meters of factory buildings, with a planned total investment of 350 million yuan. It mainly engages in the research, application, and production of special performance aluminum alloy materials such as automotive lightweighting and precision profiles.
