A Long-Span Bracing Frame is a high-performance structural system engineered for large-span buildings and facilities (span ≥30m), integrating lateral stability enhancement, load-bearing optimization, and spatial flexibility. Manufactured with Q355B/Q460 high-strength steel and Q690 ultra-high-strength steel (critical bracing members), this product features an optimized truss-type or space frame design—adopting triangular, trapezoidal, or curved bracing configurations—to efficiently distribute vertical loads (dead load + live load) and lateral forces (wind, seismic action) across the entire structure. The bracing members utilize box-section, H-beam, or circular pipe cross-sections (customizable from 200×200mm to 600×600mm) with yield strength ≥345MPa, ensuring exceptional lateral stiffness (≥1.8×10⁵ kN/m) and anti-buckling performance, while limiting structural lateral displacement to ≤L/1000 (L=span length) and vertical deflection to ≤L/500, fully complying with GB 50017-2017 and AISC 360 structural standards. Connection nodes employ high-strength bolted joints (10.9/12.9 grade) or hybrid bolt-welded connections reinforced by stiffeners, with factory prefabrication rate ≥92% to guarantee component precision (dimension error ≤±0.8mm) and reduce on-site construction time by 50% compared to traditional methods. The surface is treated with hot-dip galvanizing, fluorocarbon coating, or weathering steel finish, providing salt spray resistance ≥1200 hours and adapting to indoor, outdoor, and coastal environments. Key features include lightweight design (40% lighter than concrete bracing systems) to reduce foundation load, spatial truss optimization via finite element analysis (FEA) to eliminate stress concentration, and compatibility with large-span architectural forms (e.g., curved roofs, cantilevers). It supports customizable span sizes (30m-120m), bracing spacing (3m-8m), and load-bearing capacities (up to 5kN/m²), suitable for both single-span and multi-span structures. Professional services include wind tunnel testing, seismic performance simulation, BIM-based installation modeling, and on-site supervision, ensuring the frame meets the strict safety, durability, and spatial requirements of large-span projects.
Long-Span Bracing Frames are critical structural solutions for large-span buildings and infrastructure, trusted for their ability to balance stability, efficiency, and architectural flexibility. Certified by GB 50017-2017, AISC 360, and ISO 9001, they meet international large-span structural standards, making them a preferred choice for stadiums, exhibition centers, and industrial facilities. These frames are widely used in public buildings (stadiums, gymnasiums, exhibition halls, airport terminals), industrial facilities (large-span workshops, warehouses, logistics centers), transportation infrastructure (long-span bridges, railway stations with overhead platforms), cultural buildings (museums, theaters with super-large column-free spaces), and special structures (greenhouses, aircraft hangars, stadium canopies). They are particularly essential for projects requiring column-free large spaces, such as exhibition centers (span 50m-100m) and industrial workshops (span 30m-80m), where traditional bracing systems cannot meet span and load requirements. The system’s lightweight and prefabricated design also makes it ideal for projects in remote areas or with tight construction schedules. The minimum order quantity is 1 set (customized per project), with full tailoring based on span size, load conditions, architectural design, and environmental requirements. Competitive project-based pricing and flexible delivery terms (20-45 workdays based on complexity) support large-scale construction schedules, while a monthly supply capacity of 70 project sets ensures timely delivery. Customization options include corrosion-resistant upgrades (316L stainless steel, super duplex stainless steel) for coastal or industrial environments, fire-resistant coating integration (fire resistance ≥2 hours) for public buildings, and weathering steel for architectural rust-patina effects in landscape structures. Whether it's for new large-span construction, existing structure span extension, or special-shaped large-span projects (curved, inclined), the Long-Span Bracing Frame delivers safe, efficient, and space-optimized structural performance.
