Airport Membrane Canopy

Airport Membrane Canopy refer to architectural systems employing membrane materials in key areas such as terminal buildings, platform canopies, and connecting corridors. These structures are designed to meet both the functional demands and aesthetic standards of modern aviation facilities, offering innovative solutions for large-span coverage and environmental adaptability.

Terminal Roof / Atrium

Structural Form: Systems such as cable domes, tensioned membrane structures, or ETFE air cushion roofs are commonly utilized. These enable the creation of vast, column-free spaces that align with the grand scale of airport terminals.

Key Requirements: High light transmittance is essential to reduce dependency on artificial lighting and lower energy consumption. Strong wind resistance is critical to withstand high winds in exposed airport environments. Excellent self-cleaning properties are also vital to minimize maintenance demands at significant heights.

Platform Canopy / Boarding Bridge Corridor

Structural Form: Frame-supported membrane systems and tensioned membrane structures are frequently employed. Their designs often feature curved or folded forms, complementing the linear layout of passenger platforms.

Key Requirements: These structures must provide extensive coverage, ensure efficient water drainage, and possess high fatigue resistance to endure vibrations from continuous passenger flow. Strong corrosion resistance is also necessary to withstand the unique environmental conditions around airports.

Entrance Hall / Landscape Corridor

Structural Form: Retractable membrane structures and free-form tensile designs are often chosen here. They serve a dual purpose: providing functional shelter and creating a distinctive architectural landmark that enhances the visual identity of the airport entrance.

Key Requirements: Unique and dynamic aesthetics are a priority, alongside ensuring smooth passenger circulation. High safety redundancy is mandatory to meet the stringent standards required for high-traffic public areas.

High-End Projects: For iconic terminal buildings, ETFE foil (often in air-filled cushion assemblies) is the preferred choice. It offers exceptional light transmittance (exceeding 90%), superior self-cleaning performance, and is remarkably lightweight. A prominent example is its extensive use in parts of Beijing Daxing International Airport. PTFE-coated fiberglass membrane is another premium option, valued for its outstanding weather resistance, non-combustibility, and long service life, making it suitable for permanent terminal structures.

Standard Applications: For functional areas like platform canopies, PVC-coated polyester fabric is widely used. This material offers a favorable balance of cost-effectiveness, ease of installation, and durability, making it a practical choice for auxiliary spaces.
