Plastic steel profiles refer to PVC profiles used for making doors and windows. Because doors and windows insufficient rigidity processed solely with PVC profiles, steel is usually added to the cavity to enhance the firmness of doors and windows, therefore, plastic doors and windows made by adding steel inside the profile are usually called plastic steel doors and windows.

With the wide use of plastic steel doors and windows, PVC profiles used to make plastic steel doors and windows are traditionally called plastic steel profiles. Plastic steel is also used as a common material for guardrail.

i. Characteristics of plastic steel
plastic steel profiles are referred to as plastic steel for short. The main chemical composition is PVC, so they are also called PVC profiles. It is a new type of building material widely used. Due to its excellent physical properties such as rigidity, elasticity, corrosion resistance and aging quality resistance, it is usually used as a good generation of nonferrous metals such as copper, zinc and aluminum.
It is mainly used for pushing and pulling, flat opening doors and windows, guardrails, pipes and ceiling materials in House buildings. It is also widely used in automobile engine protective plate through new technological process processing. It is not only light in weight, but also has good toughness, it has excellent properties and is sometimes called alloy plastic steel.
II. Main functions
1. Heat preservation and energy saving: the multi-cavity structure of plastic steel profiles has good heat insulation performance and low heat transfer coefficient, which is only 1/357 of steel and 1/1250 of aluminum, its economic and social benefits are huge.
2. Air tightness: rubber seal and wool tops are installed in all gaps of plastic steel doors and windows, so its air tightness is much higher than that of aluminum alloy doors and windows. However, the air tightness of plastic steel flat doors and windows is higher than that of sliding window. In general, the air tightness of casement window can reach five levels, and that of sliding window can reach two levels.
3. Watertightness: because the plastic steel profile has a unique multi-cavity structure and has an independent drainage chamber, the water in both the frame and the fan can be effectively discharged. The watertightness of plastic steel casement window is much higher than that of sliding window. Generally, the watertightness of casement windows can reach five levels, and the watertightness of sliding window can reach three to four levels.
4. Wind pressure resistance: in The Independent plastic cavity, steel lining of 1.5~3mm thick can be added, and according to the local wind pressure value, building height, hole size, window design to choose the thickness of plastic steel and profile series, in order to ensure the requirements of building on doors and windows. High-rise buildings can choose large section sliding window or inner casement window, wind pressure strength can reach more than six levels, low storied building can choose outer casement window or small section sliding window, wind pressure strength is generally in three levels.
5. Corrosion resistance: plastic steel profiles have unique formula and good corrosion resistance. For example, anti-corrosion hardware and stainless steel profiles are selected, and their service life is about 10 times that of copper window.
6. Weather resistance: plastic steel profiles adopt a unique formula to improve their cold resistance. Plastic steel doors and windows can be used in environments with large temperature difference (-50℃ ~ 70℃) for a long time, and the hot sun exposure and humidity will not cause deterioration, aging, embrittlement and other phenomena, the earliest plastic-steel doors and windows have been used for 30 years, and their materials are as good as before. According to this calculation, the service life of plastic-steel doors and windows can reach more than 50 years under normal conditions.
