Plastic Steel Doors and Windows
Product Overview
Plastic steel doors and windows are architectural products that combine thermal insulation, energy efficiency, safety, and environmental friendliness. The main body is made of UPVC modified polyvinyl chloride plastic, which, after adding impact-resistant, weather-resistant, and stabilizing agents, is extruded at high temperatures to form a hollow multi-chamber structure. A galvanized steel liner is inserted inside to enhance rigidity, achieving a composite load-bearing structure of plastic wrapped around steel, effectively compensating for the shortcomings of insufficient plastic strength. The product boasts wind-pressure resistance ratings of 4–6, capable of withstanding winds of force 7–9; for high-rise buildings, an optional thickened steel liner can achieve a rating of up to 7. Water-tightness ratings range from 3 to 4, ensuring no leaks during rainy or windy conditions. Air-tightness ratings are between 4 and 5, providing excellent sealing to prevent drafts and block windblown dust, fully meeting the needs of residential homes, apartment complexes, and various other settings.
Product Structure and Performance Principles
The core structure of plastic steel doors and windows is a plastic-wrapped steel composite design. The outer layer of UPVC modified polyvinyl chloride plastic is formed through high-temperature extrusion into a hollow multi-chamber structure. This multi-chamber design significantly enhances the profile’s thermal insulation and heat retention properties. Combined with added impact-resistant, weather-resistant, and stabilizing agents, the profiles exhibit outstanding impact resistance and weather durability, adapting well to diverse regional climates without easily aging or deforming. Meanwhile, the internal galvanized steel liner reinforces overall structural rigidity, addressing the issue of insufficient plastic strength, ensuring that the doors and windows maintain structural stability under strong wind loads, avoiding deformation or cracking.
In terms of sealing performance, plastic steel doors and windows employ a multi-seal strip design paired with precise profile jointing techniques, greatly improving both air-tightness and water-tightness. This effectively prevents windblown dust and debris from entering indoors while also averting leaks during inclement weather. Moreover, the hollow plastic profiles themselves possess good insulating properties; when used with insulated glass, they further reduce heat transfer between indoors and outdoors, helping maintain a stable indoor temperature, lowering energy consumption for air conditioning and heating, thus achieving energy-saving and thermal-insulation benefits.

Solutions to Industry Pain Points
1. Addressing the vulnerability of traditional doors and windows: Old iron windows often rust and seize up after exposure to rain, while wooden windows warp and crack due to moisture. Plastic steel doors and windows resist rust, decay, and cracking, boasting a longer service life and lower maintenance costs.
2. Solving poor thermal insulation in ordinary windows: Single-pane windows lose heat quickly, leaving interiors cold in winter and hot in summer, driving up electricity and heating bills. Plastic steel doors and windows feature multi-chamber profiles paired with insulated glass, delivering strong thermal insulation and helping maintain a stable indoor temperature, significantly reducing energy consumption.
3. Tackling inadequate sealing in old windows: Cracks and gaps in aged windows lead to drafts, dust infiltration, and noise pollution, especially when exposed to wind and street traffic. Plastic steel doors and windows adopt a multi-seal strip design, blocking wind and dust while effectively insulating against noise, thereby enhancing indoor living comfort.
4. Mitigating high project budgets: Aluminum-clad wood doors and windows tend to be expensive, placing heavy cost pressure on large-scale projects. Plastic steel doors and windows offer superior cost-effectiveness, effectively controlling procurement expenses while meeting performance requirements—making them ideal for large-scale project installations.
5. Preventing hardware corrosion in kitchens and bathrooms: In humid kitchen and bathroom environments, ordinary door and window locks often rust and jam. Plastic steel materials resist moisture and humidity, ensuring durable, smooth operation without frequent replacement of hardware components.
