What are the characteristics of plastic-steel profiles?

Plastic steel profiles are cost-effective. Compared with wooden doors and windows and aluminum alloy doors and windows, the price of plastic is much cheaper, and the service life and wear resistance of plastic are better, and it can resist ultraviolet rays, is not easy to age, and has excellent wind erosion and earthquake resistance. The color of plastic-steel profiles is very rich. A major feature of plastic materials is that they are colorful and not easy to fade and dye. Wooden doors and windows need to be painted if they want bright colors, and the paint is not only pungent, but also contains harmful substances, and it will become mottled and old after a period of use. In contrast, the advantages of plastic-steel profiles are very prominent. Plastic steel profiles have good thermal insulation performance. The structural design of plastic steel profile is multi-cavity structure, which can insulate heat. The insulation of plastic-steel profiles has been proved by scientific experiments, and plastic-steel doors and windows are used in the same type of rooms. Summer will be about 5℃ lower than the room with aluminum doors and windows. Plastic steel profiles have good sound insulation effect. The doors and windows of plastic-steel profiles are all hollow glass designs, that is, there is a gap between the two layers of glass. This design greatly improves the sound insulation function of doors and windows, ensures that the room is not disturbed by external noise, and gives people a quiet rest space.
