Why plastic steel doors and windows are preferred as building doors and windows materials

Heat preservation and energy saving:
Plastic steel doors and windows are designed with multi-cavity structure, which has excellent heat insulation performance. Its heat transfer coefficient is very small, only 1/357 of steel and 1/1250 of aluminum.
Investigation by relevant departments shows that the use of plastic steel doors and windows in the room in winter, the indoor temperature can be increased by 4-5 ℃ compared to the use of wooden windows.
The wide use of plastic steel doors and windows has saved a lot of wood, aluminum and steel materials for the country, and its production energy consumption is also low, only 1/45 of steel and 1/8 of aluminum.
Corrosion resistance:
The plastic steel profile has a unique formula that makes it have good corrosion resistance.
The corrosion resistance of plastic steel doors and windows mainly depends on the choice of hardware, such as anti-corrosion hardware, stainless steel materials, its service life can be up to 10 times that of steel windows.
Air tightness and water tightness:
When installing plastic steel doors and windows, all gaps are equipped with rubber sealing strips and wool strips to ensure that their air tightness is much higher than that of aluminum alloy doors and windows.
The unique multi-cavity structure of plastic steel doors and windows makes it have an independent drainage cavity, which can effectively drain the water and keep the doors and windows dry.
Wind pressure resistance:
In the independent plastic cavity, 2-3mm thick steel can be filled, and the thickness and profile series of reinforcing ribs can be selected according to the wind pressure value, building height, hole size and window design to meet the requirements of different buildings for doors and windows.
Sound insulation:
The plastic steel profile itself has a good sound insulation effect, and the sound insulation effect is more ideal when the double glass structure is used.
Weather resistance:
Plastic steel doors and windows can be used for a long time in the environment with large temperature difference (-50 ℃ ~ 70 ℃), and are not easy to deteriorate, aging and embrittlement.
