PVC-steel Composite Windows

Technical Specifications

Product Features & Applications

The core advantage of PVC-steel composite windows lies in their balanced performance. The outer PVC profile offers excellent thermal insulation, soundproofing, and corrosion resistance, while the inner galvanized steel reinforcement provides strong support, improving the frame’s resistance to deformation and impact. The multi-layer sealing system effectively prevents rainwater, noise, and temperature changes, making these windows more stable compared to pure PVC windows.

Key Applications:

Standard residential homes

Villa annexes

Office space annexes

Shops and commercial spaces

These windows support various opening methods, including casement and tilt-and-turn designs, making them ideal for residential comfort and light commercial use, offering a great balance between performance and cost.

Production Process

The production process follows strict quality control for PVC-steel composite windows. PVC profiles are infused with anti-aging and stabilizing agents, then extruded into shape. Galvanized steel reinforcements are tightly embedded within the PVC profile, ensuring no loosening.

The frame joints are processed with high-precision CNC machines, sealed with specialized adhesive strips and connectors, ensuring tight seams and enhancing air and water tightness.

Glass and Frame Connection:

A three-layer EPDM seal strip is used between the glass and frame, providing durable and strong sealing performance.

Hardware and Accessories:

The hardware is designed specifically for PVC-steel profiles, ensuring strong weight-bearing capacity and smooth operation.

Surface treatment options include PVC solid colors or laminated coatings, ensuring uniformity, weather resistance, and long-lasting aesthetics.

Core Advantages

Balanced Performance:  Combines PVC’s thermal insulation and environmental benefits with the strength of steel reinforcement, delivering a comprehensive performance solution.

Stability and Durability:  The steel reinforcement improves deformation and impact resistance, giving the window a longer lifespan.

Excellent Sealing:  Multiple sealing layers provide superior water, sound, and thermal insulation, enhancing living comfort.

Corrosion and Weather Resistance:  PVC exterior protects against corrosion, while galvanized steel reinforcement resists rust, making the windows adaptable to various climates.

Balanced Cost-Effectiveness:  Offers better performance than pure PVC and standard aluminum windows, at a moderate price, ideal for diverse applications.

Comparison with Similar Products

Structure & Design

The PVC-steel composite structure consists of "PVC outer layer + galvanized steel reinforcement + insulated tempered glass." The steel reinforcement is securely fixed inside the PVC profile using specialized clips, ensuring uniform force distribution and enhancing the frame's overall strength. The frame and sash connection features a step-style sealing structure, enhanced by a three-layer EPDM seal strip for a stronger seal.

Opening Options:

Casement windows

Tilt-and-turn windows

The design supports single, double, or triple panel configurations. The glass options include clear, frosted, and Low-E types to meet varying lighting and energy-saving needs. The frame is primarily available in white or gray, with optional laminated wood grain finishes, ideal for minimalist, traditional, or modern home décor styles.

Hardware:

Silent hardware for smooth, noise-free operation.

Functional and aesthetic, offering both practicality and design appeal.

Usage & Maintenance Tips

After installation, check the attachment of the steel reinforcement and PVC profile, the tightness of the hardware, and the integrity of the sealing strips to ensure stability and performance.

Use a soft cloth and neutral cleaning agent to clean the windows. Avoid sharp objects that may scratch the profile or seals.

Avoid strong impacts on the frame to prevent damage to the PVC profile or distortion of the steel reinforcement.

Regularly (every 6 months) inspect the seals and hardware. If any signs of aging, jamming, or detachment appear, replace them promptly to maintain performance.

Avoid prolonged exposure to corrosive substances to prevent damage to both the PVC profile and steel reinforcement, extending the window's lifespan.

FAQ

Q: Will the steel reinforcement of PVC-steel windows rust?

A:  No, the steel reinforcement undergoes a galvanizing process to ensure excellent rust resistance. It is fully encased by the PVC profile, isolating it from moisture and air to prevent rusting, ensuring long-term stability.

Q: Can PVC-steel windows be used in high-rise buildings?

A:  Yes, the steel reinforcement allows the frame to achieve wind resistance levels above 8, making it suitable for use in high-rise buildings, with sturdy hardware that ensures safety in high-wind conditions.
