Product description

1.Heavy-Duty Robust Structure, Excellent Wind Resistance

The 155mm wide, thick profile cross-section offers high structural strength, capable of supporting larger/heavier glass panels, with outstanding wind resistance for building entrances in windy areas.

2.Bridge-Cut Aluminum + Multi-Cavity Design, Extreme Thermal Insulation

Made of bridge-cut aluminum alloy, with a standard multi-cavity structure and PA66 GF25 thermal insulation strips, it significantly reduces indoor-outdoor heat transfer, suitable for cold regions and energy-efficient buildings.

3.High-Performance Glass, Quiet & Constant-Temperature Experience

Standard triple-glazed insulated tempered glass (optional Low-E or inert gas filled), balancing safety, sound insulation and extreme thermal insulation to create a quiet, constant-temperature indoor environment.

4.Professional Hardware System, Stability & Sealing Assurance

Equipped with load-bearing hinges (e.g., 3D adjustable hidden hinges) and a multi-point locking system, ensuring door stability and full-perimeter sealing for enhanced safety and performance.

5.Customizable Appearance, Adapt to Diverse Styles

Offers a wide range of powder coating colors, supporting dual-color co-extrusion (different colors inside/outside) to match the aesthetic needs of various buildings.
