Analysis: Plastic steel doors and windows product classification
Plastic steel doors and windows are manufactured using polyvinyl chloride (UPVC) as the primary material, combined with specific amounts of stabilizers, pigments, fillers, and UV absorbers. After extrusion molding, the profiles are cut, welded, or fastened together to form the door and window frames. These frames are then fitted with sealing strips, top strips, hardware components, and other accessories. To enhance structural rigidity, especially in longer profiles, a steel reinforcement bar is often inserted into the internal cavity. This combination of materials gives the product its name—plastic steel doors and windows. Types of Plastic Steel Doors and Windows Plastic steel doors and windows come in various types based on their opening mechanisms and functions. Some common classifications include fixed windows, upper-hung windows, middle-hung windows, lower-hung windows, vertical pivot windows, swing windows, sliding casement windows, roller-type windows, bottom-hung swing doors, sliding doors, push-pull casement windows, folding doors, floor spring doors, lift-and-slide doors, push-pull folding doors, and inward-opening sliding doors. In addition to these functional categories, plastic steel doors and windows can also be classified by performance. For instance, they may be standard doors and windows, soundproof doors and windows, or thermal-insulated doors and windows. These variations cater to different environmental and comfort requirements. Furthermore, plastic steel doors and windows are often divided based on their application areas. They can be used as interior doors and windows for indoor spaces or exterior doors and windows designed to withstand outdoor conditions and weather exposure. Overall, plastic steel doors and windows offer a durable, low-maintenance alternative to traditional metal or wooden options, making them a popular choice in modern construction and home improvement projects.
