Project Background

As one of the world’s largest aviation hubs, Beijing Daxing International Airport embodies the design philosophy of a “future-ready airport,” demanding exceptional safety, durability, and aesthetics from its building materials. Color steel (pre-coated galvanized steel) and color aluminum (coated aluminum alloy) emerged as core materials for roofing systems, facades, and interior finishes, leveraging their lightweight properties, weather resistance, and design versatility.

Key Applications of Color Steel

1. Large-Span Roofing
The terminal’s undulating roof design utilized color steel for its high strength-to-weight ratio (1/3 lighter than conventional materials), enabling column-free spans, reduced structural load, and accelerated construction.

2. Energy Efficiency & Sustainability
Reflective coatings on color steel reduced solar heat absorption by 70%, while insulated sandwich panels minimized HVAC energy consumption. Fully recyclable materials aligned with the airport’s LEED Gold certification goals.

Innovations in Color Aluminum

1. Dynamic Facade System
Customized color aluminum panels formed a parametric facade mimicking “phoenix wings,” balancing shade and natural lighting. Anodized finishes guaranteed 30-year corrosion resistance, suitable for Beijing’s harsh weather.

2. Aesthetic & Functional Interiors
Matte-finish aluminum for check-in counters and signage reduced glare while enhancing visual comfort. Antimicrobial coatings in high-traffic zones promoted hygienic conditions.

Project Achievements

Efficiency: Modular installation of pre-fabricated panels reduced roofing construction time by 40%.

Cost Savings: 25% lower lifecycle maintenance costs with materials designed for 50+ years of service.

Global Recognition: Awarded “World’s Best Airport Design 2021,” with material innovation as a decisive factor.
