Understand the material of upvc doors and windows
Plastic steel, in fact, is a rigid polyvinyl chloride profile (UPVC), a polymer plastic. The profiled material made by the die extrusion process. Due to its low strength, it is necessary to add a steel lining to its cavity to achieve the purpose of reinforcement. , which is the origin of the name of the plastic-steel profile. The obvious advantages of plastic steel are its good energy saving and low cost. For example, in the severe cold region of Northeast China, when people choose doors and windows, they are basically made of plastic steel; the disadvantage of plastic steel: the strength of the material itself is lower than that of metal. easily damaged.
