  • Our theater space frame offers an advanced solution for modern theaters, auditoriums, and performance venues seeking both aesthetic appeal and structural reliability. Designed for long spans and complex architectural geometries, this space frame for theaters combines modular flexibility, lightweight steel construction, and high load-bearing performance to create iconic, safe, and visually striking theater structures.


    Crafted from high-strength Q235B or Q33B steel, each member is precision-engineered and coated with epoxy zinc-rich primer or anodized finish for long-term durability and resistance to corrosion. The frame's structural depth ranges from 31.2 to 40 meters, accommodating various roof designs while maintaining optimal weight-to-strength ratios. This ensures the structure is not only safe but also cost-efficient in terms of material usage and installation labor.


    The modular design allows each prefabricated unit to be customized in length and arrangement, simplifying transportation and enabling rapid theater structure design implementation on-site. Our bolt-ball node connections provide secure, flexible, and universal interfacing between modules, ensuring easy assembly and adaptability for future modifications or expansions. The grid pattern, whether a tri-circular arch shell or a square pyramid shell, can be tailored to the aesthetic and functional needs of any venue.


    Safety is at the forefront of our design. The theater space frame withstands wind speeds up to 30 m/s and supports uniform loads of 3.5 kN/m, exceeding typical roofing requirements while meeting the latest GB50583-2020 and JGJ7-2010 structural standards. The frame's self-weight is optimized at 5.5 kg/m, enabling lighter foundations and reducing overall construction costs. Additionally, modules can be installed using block-by-block, high-altitude assembly, or sliding methods, offering versatile solutions for any site condition.


    Our design not only focuses on engineering precision but also on aesthetic appeal. With customizable colors, finishes, and module arrangements, architects can create dramatic visual effects for theater roofs and interiors. This combination of flexibility, strength, and elegance ensures that the space frame for theaters enhances both structural integrity and audience experience.


    From a commercial standpoint, investing in this theater structure design solution provides long-term value. Each frame is designed for a 50-year service life, backed by CE and ISO9001 certifications. Whether constructing a new performance venue or upgrading an existing facility, our space frame delivers an efficient, reliable, and visually impressive solution for every theater project.


    In summary, this modular theater space frame system is ideal for architects, contractors, and venue owners who demand superior structural performance, rapid installation, and aesthetic versatility. It transforms traditional theater roof design into a modern, durable, and scalable solution while optimizing cost, safety, and functionality. Enhance your venue with a space frame that exemplifies innovation, strength, and architectural excellence.
