Steel frame construction for large span structures is a specialty of Guangdong Junyou Steel Structure Co., Ltd., leveraging steel’s unique combination of high strength, ductility, and lightweight properties to create expansive, unobstructed spaces. Large span structures—defined as those with spans exceeding 20 meters—are common in applications like stadiums, exhibition halls, aircraft hangars, and industrial warehouses, where open space is critical. The company’s approach involves engineering a steel frame system (composed of beams, trusses, or arches) that distributes loads (dead weight, live loads, wind, seismic forces) across the span without relying on internal supports. High-grade steel (Q355B or higher) is used, with tensile strength exceeding 355 MPa, ensuring the frame can withstand extreme forces while maintaining structural integrity. Advanced design software (e.g., SAP2000, Tekla) is employed to model and optimize the frame, ensuring efficiency and safety. Prefabrication is key: frame components are cut, welded, and drilled in the factory to precise tolerances, then transported to the site for assembly via high-strength bolts. This method reduces on-site construction time by 40-60% compared to traditional concrete spans. Steel frame large span structures offer exceptional flexibility: they can be designed with clear spans up to 100+ meters, accommodate future modifications (e.g., adding mezzanines), and integrate features like overhead cranes or retractable roofs. For projects demanding vast, unobstructed space without compromising on strength or safety, this construction method is unparalleled.
