  • Our airport terminal space frame roof is an advanced modular structure designed to meet the modern demands of large-scale transportation hubs. Engineered for high strength, durability, and flexibility, this prefabricated steel space frame offers a robust solution for airports, terminals, and other commercial facilities requiring expansive, unobstructed roofing. With a span range of up to 120 meters, it enables architects and engineers to achieve vast interior spaces without intermediate supports, creating a sense of openness and architectural elegance.


    Constructed from premium Q235B or Q33B steel, the frame ensures maximum load-bearing capacity while maintaining a lightweight profile, facilitating efficient transportation and high-altitude assembly. Each module is precisely fabricated for seamless integration, allowing customizable lengths tailored to specific project requirements. The structural depth ranges from 31.2 to 40 meters, providing exceptional stability while optimizing material usage.


    The surface coating options, including epoxy zinc-rich primer and anodizing, offer superior resistance against corrosion, extending the lifespan of the structure even in harsh environmental conditions. Our design also prioritizes wind and snow resistance, capable of withstanding wind speeds up to 30 m/s and accommodating snow loads in compliance with GB50583-2020 standards.


    Installation is streamlined with versatile methods such as high-altitude assembly, block-by-block construction, or sliding installation, making the system suitable for both new projects and renovations. The bolt-ball joint nodes combined with conical connectors ensure reliable and uniform connections, enhancing structural integrity and ease of maintenance.


    In addition to its engineering excellence, the airport roof frame is compliant with international standards, including CE and ISO9001, providing assurance of quality and performance. The frame supports customizable aesthetics, including color options and architectural finishes, to match the design vision of each terminal project.


    This modular space frame is not only practical but also sustainable. Its lightweight design reduces material consumption and transportation costs, while the long design service life of 50 years ensures that the structure remains functional and safe for decades. Ideal for large-scale airport terminals, exhibition halls, and other public infrastructure, this space frame is the preferred solution for architects and engineers seeking a combination of durability, flexibility, and modern design appeal.


    Whether you are planning a new terminal roof or upgrading an existing facility, our airport terminal space frame provides a versatile, high-performance, and visually striking solution. With a focus on structural reliability, safety, and aesthetic versatility, it guarantees that your project meets both functional requirements and architectural ambitions. Choose our modular space frame system to elevate your airport design with efficiency, strength, and enduring quality.
