Characteristics of plastic steel profiles

12 Jun, 2024

Material and composition: The main raw material is polyvinyl chloride (PVC) resin, and a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., are made by extrusion molding process.
Physical properties: excellent rigidity, elasticity and corrosion resistance, as well as good anti-aging properties. Because of its unique physical properties, it is often used as a substitute for non-ferrous metals such as copper, zinc, and aluminum.
Lightweight and environmental protection: plastic steel profiles are lightweight, non-toxic, tasteless, fire retardant, and have the advantages of recycling, reflecting its environmental characteristics.
Rich colors: plastic steel profiles have a variety of colors, which can meet different architectural styles and decoration needs, especially in indoor and outdoor decoration.
Durability: Adding reinforced steel in the profile cavity significantly improves the strength of the profile, which has the effect of earthquake resistance and wind erosion resistance.
The design of the multi-cavity structure prevents water from entering the reinforced steel cavity, effectively avoids corrosion of the steel, and prolongs the service life of the doors and windows.
The addition of anti-ultraviolet components improves the weather resistance of plastic steel profiles, so that they can be used in tropical and other areas with strong ultraviolet rays.
Thermal insulation and sound insulation performance: the thermal conductivity of plastic steel profiles is much lower than that of aluminum profiles, and the design of multi-cavity structure achieves the heat insulation effect. Research shows that the use of plastic steel doors and windows in the summer indoor temperature than aluminum doors and windows room average 5-7 ℃ lower, winter is 8-15 ℃ higher. The installation of hollow glass sealed plastic steel doors and windows has good sound insulation performance, suitable for residential use in downtown areas and other need to isolate noise.
Air tightness and water tightness: all gaps of plastic steel doors and windows are equipped with rubber sealing strips and wool strips, and the air tightness is much higher than that of aluminum alloy doors and windows. The unique multi-cavity structure ensures that the accumulated water in both the frame and the fan can be effectively discharged, and the water tightness is excellent.
Wind pressure resistance: 1.5~3MM thick steel lining can be filled in the independent plastic cavity, and the appropriate plastic steel thickness and profile series can be selected according to the specific situation to meet the wind pressure resistance requirements of the building for doors and windows.
Corrosion resistance: The plastic steel profile adopts a unique formula and has good corrosion resistance. Combined with anti-corrosion hardware and stainless steel profiles, its service life can reach about 10 times that of steel windows.
Weather resistance: plastic steel profiles can be used for a long time in an environment with a large temperature difference (-50 ℃ ~ 70 ℃), sun exposure and humidity will not cause deterioration, aging, embrittlement and other phenomena, and the service life can reach more than 50 years under normal conditions.
