Properties of PVC Plastic Steel

Plastic steel doors and windows are multi cavity structures with good thermal insulation performance. Their heat transfer performance is very small, only 1/357 of that of steel and 1/250 of that of aluminum. It can be seen that plastic doors and windows have significant thermal insulation and insulation effects, especially for modern buildings with heating and air conditioning equipment.

Survey comparison shows that the indoor temperature of rooms with plastic steel doors and windows can be 4-5 degrees higher in winter than those with wooden doors and windows; The use of double-layer glass in northern regions yields better results. According to the test of the Institute of Physics, the heat transfer coefficient of single glass steel and aluminum window is 64W/M2K; The heat transfer coefficient of single glass plastic steel window is about 47W/M2K; The heat transfer coefficient of ordinary double glass steel and aluminum windows is 3. About 7W/M2K; The heat transfer coefficient of double glass plastic steel window is about 2. 5W/M2K。 Doors and windows account for 30% of the building’s exterior envelope area, and their heat dissipation accounts for 49%. This indicates that plastic steel windows have good energy-saving benefits

The physical properties of plastic steel doors and windows mainly refer to the air permeability (air tightness), rainwater leakage (water tightness), wind pressure resistance, and insulation and sound insulation performance of PVC plastic steel doors and windows. Due to the unique multi chamber structure of plastic steel door and window profiles and the fusion welding process, all gaps in the installation of plastic steel doors and windows are equipped with door and window sealant strips and wool strips, thus possessing good physical properties.

Plastic steel doors and windows have good corrosion resistance due to their unique formula. Secondly, the corrosion resistance of plastic steel windows depends on the use of hardware. In normal environments, hardware is metal products, while in industries with corrosive environments such as food, medicine, hygiene, chemical, coastal areas, and rainy and humid areas, anti-corrosion hardware (engineering plastic) is selected, which has a service life of 10 times that of plastic steel doors and windows.

Plastic steel doors and windows adopt special formulas, with the addition of ultraviolet absorbers and low-temperature impact resistance agents in the raw materials, thereby improving the weather resistance of plastic steel doors and windows. Long term use in temperature climate environment, no discoloration, deterioration, aging, embrittlement and other phenomena in hot sun, rainstorm, dry and humid changes between – 30 ℃ and 70 ℃. Plastic steel windows have been used in Western Europe for thirty years, and their materials are intact as before.

Plastic steel doors and windows do not self ignite, do not support combustion, self extinguish after leaving the fire, are safe and reliable, and meet fire protection requirements. This performance further expands the range of use of plastic steel doors and windows.

Plastic steel doors and windows use high-quality electrical insulators made of profiled materials, which are non-conductive and have a high safety factor.

Plastic steel doors and windows are of fine and smooth texture, with consistent quality both inside and outside. They do not require special surface treatment and are easy to process. After cutting and fusion processing, the length, width, and diagonal of the finished doors and windows can be within plus or minus 2mm. The processing accuracy and angular strength can reach over 3000N.

The main reason is the sound insulation effect of glass, which accounts for about 80% of the area. Some sound insulation plastic steel door and window products on the market use different glass combination structures based on the resonance transmission principle of sound waves and coupling, such as hollow glass plastic steel windows and ordinary double-layer glass, to enhance the sound insulation effect of doors and windows. In terms of door and window structure, the use of high-quality adhesive strips and plastic sealing accessories has significantly improved the sealing performance of plastic steel doors and windows.

1. Plastic steel doors and windows have good insulation performance: The plastic in aluminum plastic composite profiles has a low thermal conductivity, and the insulation effect is 1250 times better than that of aluminum. In addition, it has good airtightness. In cold regions, although it is below – tens of degrees outdoors, indoors it is a different world.

2. Plastic steel doors and windows have good sound insulation: their structure has been carefully designed, and the joints are tight. The test results show that the sound insulation is 30db, which meets relevant standards.

3. Impact resistance of plastic steel doors and windows: Due to the outer surface of aluminum plastic composite profiles being aluminum alloy, they have much stronger impact resistance than plastic steel window profiles.

4. Plastic steel doors and windows have good air tightness: Multiple sealing strips or adhesive strips are installed at each gap of the aluminum plastic composite window, with a first level air tightness, which can fully exert the air conditioning effect and save 50% of energy.

5. Good water tightness: The doors and windows are designed with rainproof structures to completely isolate rainwater from the outside, and the water tightness meets relevant national standards.

6. Plastic steel doors and windows have good fire resistance: Plastic steel doors and windows are made of UPVC material, which does not self ignite or support combustion.

7. Plastic steel doors and windows have good anti-theft performance: Aluminum plastic composite windows, equipped with excellent hardware accessories and high-end decorative locks, make thieves helpless

8. Maintenance free: Aluminum plastic composite profiles are not susceptible to acid and alkali corrosion, will not turn yellow or fade, and almost do not require maintenance. When dirty, water and cleaning agent can be used to scrub, and after cleaning, it will be clean as before.

9. Best Design: Aluminum plastic composite windows are scientifically designed and use reasonable energy-saving profiles, which have been recognized and praised by national authoritative departments and can add luster to buildings.
