Our modular spherical and geodesic dome structures are engineered for modern industrial, commercial, and public architecture, offering a perfect blend of strength, efficiency, and aesthetic appeal. Designed using high-strength Q235B or Q33B steel, these structures provide exceptional durability and long-term performance, making them an ideal choice for large-span roofing systems, exhibition halls, sports facilities, greenhouses, and landmark buildings.

The prefabricated space frame truss modules allow for rapid on-site assembly while minimizing labor costs and construction time. Each module is precisely fabricated with circular hollow steel sections, ensuring optimal load distribution and structural stability. The unique tri-circular arch shell or square pyramid shell grid patterns provide both functional efficiency and visually striking architectural possibilities. With spans customizable up to 120 meters, these dome systems accommodate a wide range of building scales while maintaining structural integrity.

Safety and resilience are central to our design philosophy. The structures are engineered to withstand wind speeds of up to 30 m/s and designed according to local and international building codes, including GB50583-2020 and JGJ7-2010. The steel members are protected with epoxy zinc-rich primer or anodized coatings, ensuring superior corrosion resistance and a design service life of up to 50 years. Modular connection systems, such as bolt-ball joints and conical connectors, simplify assembly and allow for future expansion or modification without compromising stability.

Our dome systems are also lightweight yet capable of supporting significant roofing loads, making them highly adaptable for modern architectural needs. The sliding installation method is recommended for long spans, providing efficient construction and safe high-altitude assembly. These versatile structures are suitable for industrial warehouses, sports arenas, greenhouses, exhibition halls, and any large-span application that demands durability, aesthetic appeal, and quick deployment.

Key selling points include: modular customization, rapid assembly, high-strength materials, corrosion protection, flexible grid design, international certification, large-span capacity, and long-term durability. Each dome or spherical structure can be tailored to specific project requirements, including size, grid type, surface coating, and color, ensuring a perfect match for architectural visions.

By choosing our geodesic dome and spherical steel structures, clients gain access to a robust, visually striking, and highly functional solution that meets both aesthetic and performance expectations. Ideal for high-profile projects, these structures combine modern engineering, material excellence, and construction efficiency into a single, scalable solution. Whether your project requires a tri-circular dome, a square pyramid shell, or a fully customized modular frame, our steel space-frame systems deliver unmatched quality, longevity, and design flexibility.

Transform your next architectural or industrial project with a custom geodesic dome structure designed for performance, beauty, and long-lasting reliability. These prefabricated steel frames provide the perfect balance between structural strength and lightweight design, enabling faster assembly, safer construction, and cost-effective deployment without compromising on safety or aesthetic value.
