The characteristics of plastic steel profiles are introduced in detail

Plastic steel profiles referred to as plastic steel, the main chemical composition is PVC, so it is also called PVC profiles. It is widely used as a new type of building material, because of its physical properties such as rigidity, elasticity, corrosion resistance, anti-aging properties, usually used as a substitute for copper, zinc, and other non-ferrous metals.

Its main features:

1, heat preservation and energy saving: plastic steel profiles multi-cavity structure, with good thermal insulation performance, low heat transfer coefficient, only 1/357 of steel, 1/1250 of aluminum, its economic and social benefits are huge.

2, air tightness: All the gaps in the installation of plastic steel doors and Windows are equipped with rubber and plastic sealing strips and top strips, so its air tightness is much higher than that of aluminum alloy doors and Windows, and the air tightness of plastic steel flat doors and Windows is higher than the air tightness of push-pull Windows. Under normal circumstances, the air tightness of the casement window can reach five levels, and the sliding window can reach two levels.

3, watertightness: Because the plastic steel profile has a unique multi-cavity structure, there is an independent drainage cavity, whether it is a frame or a fan of water can be effectively discharged, the water tightness of the plastic steel casement window is much higher than the push-pull window, under normal circumstances, the watertightness of the casement window can reach five levels, and the push-pull window can reach three to four levels.

4, wind pressure resistance: In the independent plastic cavity, 1.5~3MM thick steel lining can be filled, and the thickness and profile series of plastic steel can be selected according to the local wind pressure value, the height of the building, the size of the opening, and the design of the window type to ensure the requirements of the building for profile doors and Windows. High-rise buildings can choose large section sliding window or internal casement window, wind pressure strength can reach six or more, low-rise buildings can choose external casement window or small section sliding window, wind pressure strength is generally at three levels.

5, corrosion resistance: plastic steel profiles have a unique formula, with good corrosion resistance, such as the selection of anti-corrosion hardware, stainless steel profiles, its service life is about 10 times that of steel Windows.

6. Weather resistance: The plastic steel profile adopts a unique formula to improve its cold resistance, Plastic steel doors and Windows can be used for a long time in the environment with a large temperature difference (-50 ° C ~70 ° C), the sun exposure, humidity will not make it metamorphism, aging, embrittlement and other phenomena, the early plastic steel doors and Windows have been used for 30 years, the material is intact as the beginning, according to this inference, under normal conditions plastic steel doors and Windows service life can reach more than 50 years.
