Plastic steel doors and windows are primarily made from unplasticized polyvinyl chloride (UPVC) resin, combined with specific amounts of stabilizers, pigments, fillers, and UV absorbers. These materials are processed through extrusion molding to create the basic profiles. Afterward, the profiles are cut, welded, or fastened together to form the door and window frames. They are then fitted with sealing strips, top strips, and hardware components to ensure proper functionality and durability. To enhance structural rigidity, especially in longer profiles, a steel reinforcement bar is often inserted into the hollow cavities of the UPVC frame. This combination of plastic and steel gives these products their name—plastic steel doors and windows. They are widely used in modern construction due to their excellent insulation, low maintenance, and long lifespan.

Additionally, they offer superior resistance to weathering, moisture, and corrosion, making them ideal for both residential and commercial applications. The manufacturing process ensures that the final product is not only durable but also energy-efficient, contributing to reduced heating and cooling costs. With a variety of colors and designs available, plastic steel doors and windows can be customized to match different architectural styles, offering both practicality and aesthetic appeal.
