Space Frame Steel Structure for Large Venues

This Space Frame Steel Structure for Large Venues solution addresses the challenges of supporting long-span roofs and creating column-free, open spaces in large cultural, sports, and exhibition buildings, effectively overcoming the span limitations and long on-site construction periods associated with traditional structural systems. We offer rigorous raw material inspections and precision CNC machining for members and spherical nodes, with the capability to optimize structural designs based on project blueprints. We handle large-volume orders for major projects, ensuring structural stability and seismic resilience through factory-based flaw detection, thereby guaranteeing safety and on-schedule completion.

Product Structural Configuration and Engineering Standards

Structural System: Utilizes a spatial grid load-bearing system—including single, double, and triple-layer composite space frames—tailored to the venue's floor area, load requirements, and wind/snow conditions, making it compatible with diverse large-scale public building designs.

Material Standards: Strictly employs engineering-grade Q235B and Q355B steel tubing and high-strength spherical nodes. All raw materials meet inspection standards for public construction projects; non-standard profiles are strictly excluded, ensuring full compliance with material verification and supervisory acceptance procedures.

Connection Technology: Features two core processes—high-precision bolted spherical node fastening and seamless welded spherical node fusion. These ensure tight node interlocking and uniform load distribution with no structural weak points, resulting in overall stability that meets safety regulations for large, high-occupancy venues.

Protection System: Incorporates specialized protective treatments for public buildings, including industrial-grade shot-blasting for rust removal, long-lasting anti-corrosion primers and topcoats, fire-retardant coatings meeting fire safety acceptance standards, and hot-dip galvanizing for durable rust prevention. These measures ensure performance under complex conditions, including indoor, outdoor, exposed, and high-wind-pressure environments.

Project Specifications: Capable of constructing venues with ultra-long spans ranging from 30m to 120m without intermediate column supports, perfectly meeting the rigorous requirements for large-area, wide-span, and high-clearance venue construction.

Construction Methods: Supports various construction schemes—such as high-altitude bulk assembly, ground assembly followed by integral lifting, sectional hoisting, and segmental splicing—adapting to diverse site conditions including space constraints, tight schedules, and high-altitude operations.

Core Characteristics of Space Frame Structure Engineering

Public-Facility-Grade Safety Standards: Space Frame Steel Structure for Large Venues fully align with construction specifications for large-scale public venues. They undergo professional structural analysis and simulations for seismic and wind resistance. The structure features high redundancy and strong resistance to sudden loads, meeting the rigorous safety requirements of high-occupancy venues like stadiums and exhibition centers, and easily passing official completion inspections.

Elimination of Local Collapse Risks: Unlike traditional trusses or support systems that rely on single-point or single-line load-bearing, the space frame functions as an integrated, collaborative mesh structure. Loads are dispersed in all directions, ensuring that localized stress does not compromise overall structural stability, thereby significantly enhancing the service life and safety factor of large-span roofs.

Overall Project Cost: While meeting high load-bearing requirements, the design optimizes material usage; the structure's self-weight is far lower than that of traditional steel roofing. This effectively reduces the load on the main building structure and foundation construction costs, resulting in substantial savings on the civil engineering budget for large-scale venue projects.

Modular Standardization: All members and spherical nodes are mass-produced in factories with precise, uniform dimensions, angles, and hole placements. No on-site cutting or modification is required, ensuring a high degree of assembly precision. This minimizes rework and rectification issues, meeting the high construction standards required for key projects.

Balancing Utility and Aesthetics: Suitable for various iconic venue shapes—including flat, curved, arched, and complex free-form surfaces. The roof offers excellent flatness and integrates seamlessly with diverse roofing materials such as daylighting panels, aluminum-magnesium-manganese alloy sheets, and color-coated steel sheets, aligning with modern architectural aesthetics.
