The materials of plastic steel door and window equipment mainly include polyvinyl chloride (PVC) resin. PVC resin is the main raw material of plastic steel doors and windows. By adding auxiliary materials such as stabilizers, colorants, fillers and ultraviolet absorbers, it is made into door and window frames and sashes through extrusion molding, cutting, welding or screwing. In order to enhance the rigidity of the profile, steel lining (reinforcement ribs) need to be added to the cavity of the profile that exceeds a certain length.
Specific material composition of plastic steel door and window equipment
The main component of plastic steel door and window profiles is polyvinyl chloride (PVC), in addition to chlorinated polyethylene, titanium dioxide, calcium carbonate, ACR, stabilizers and ultraviolet absorbers. These components give plastic steel doors and windows excellent properties, such as thermal insulation, good sound insulation, and aging resistance.
