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, the profiles are cut, welded, or fastened together to form the door and window frames. These frames are then equipped with sealing strips, top tracks, hardware components, and other necessary accessories. To enhance structural rigidity, especially in longer profiles, a steel reinforcement bar is often inserted into the cavity. This combination of materials gives the product its name—plastic steel doors and windows. Plastic steel doors and windows come in various types, each designed for different functions and applications: 1. Common types include fixed windows, top-hung windows, center-hung windows, bottom-hung windows, vertical pivot windows, swing windows, sliding casement windows, roller 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-swinging sliding doors. 2. Based on performance, they can be categorized into standard doors and windows, soundproof doors and windows, and thermal insulation doors and windows, offering different levels of comfort and efficiency. 3. According to their usage, they are also divided into interior and exterior doors and windows, with exterior models typically designed to withstand harsher weather conditions and provide better durability. These versatile products are widely used in residential and commercial buildings due to their lightweight, corrosion-resistant properties, and energy efficiency. They offer a cost-effective alternative to traditional metal-based doors and windows while maintaining excellent strength and aesthetics.
