Are plastic steel windows made of metal or plastic

Plastic steel windows refer to windows made of plastic steel profiles, which have functions such as insulation and sound insulation, as well as strong weather resistance. Whether in the cold winter of the north or the hot summer of the south, they can greatly improve people’s quality of life and make the room warm in winter and cool in summer; Plastic steel windows are still the first choice for office buildings, schools, and street facing communities because of their excellent sound insulation performance.
Many friends do not know whether plastic steel is plastic or metal. In fact, plastic steel is neither plastic nor metal, but a special material made of polyvinyl chloride resin (PVC).
What is plastic steel window made of
Plastic steel windows can provide insulation, sound insulation, and thermal insulation, while also having good weather resistance. They are also very affordable and are a popular window type among the general public; Although metal windows are also used by many people, they are much inferior to plastic steel windows in terms of insulation and sound insulation. Let’s take a look at the main material of plastic steel windows – plastic steel profiles – and what they are made of.
The composition of plastic steel profiles.
PVC： The main component of plastic steel profiles is PVC, with a content of about 70%; The profiles made of PVC have characteristics such as high hardness and strong toughness.
But many companies crush recycled plastic steel windows and waste plastics into plastic steel profiles, which look no different from normal plastic steel profiles on the surface, but have low strength and toughness.
Calcium powder: Calcium powder can increase the hardness of plastic steel profiles, so a certain proportion of calcium powder needs to be added to plastic steel profiles; Meanwhile, the price of calcium powder is much cheaper than PVC.
This has led many companies to add a large amount of calcium powder in order to save costs and reduce the use of PVC; In this way, although the wall thickness and hardness of the plastic steel profile meet the standards, the toughness is reduced, making the plastic steel profile as fragile as glass and easily broken when stepped on.
Other auxiliary materials: Other auxiliary materials include ultraviolet absorbers, which can prevent the profile from changing color after long-term exposure to sunlight; Stabilizers can make the structure of profiles more stable; Lubricants, antimicrobial agents, titanium dioxide, etc.
Purchase plastic steel profiles and identify national standard products
Liaocheng Luyang Profile Factory was founded in 1999 and has nearly 30 years of experience in plastic steel production; All of its products comply with national standards; The wall thickness of the visible surface inside and outside is 2.5mm or more, and the non visible surface is 2.0mm or more;
The product has a PVC content of over 75% and calcium powder content of less than 30%, and belongs to low calcium plastic steel profiles; Not only does it have a high welding angle, but it also has a low weight, high hardness, and strong toughness. It will not change color or deform after 50 years of use.
