Plastic steel doors and windows are made of polyvinyl chloride (PolyVinyl Chloride, often referred to as PVC) resin as the main raw material, together with a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbents, etc., through extrusion molding materials, and then through cutting, welding or screw joints, doors and windows frame fans are made, equipped with sealant, wool, hardware, etc., while strengthening the rigidity of profiles. More than a certain length of profile cavity needs to be filled with steel lining (reinforcing bars), so the door and window made of this, called plastic steel doors and windows. Therefore, the price of plastic-steel windows is slightly higher than other types of plastic-steel windows. In addition, the manufacturing process of plastic-steel windows and doors has its own unique process, and the construction scheme of plastic-steel windows is quite different from others.
