Adjustable Bracing Node For Steel Bracing Systems GB 50017-2017 ISO 9001

Product Specification

Product Description
An Adjustable Bracing Node is a flexible and adaptable structural component designed for steel bracing systems, engineered to adjust length and align precision during installation. Manufactured with 40Cr alloy steel (adjusting screw) and Q355B steel (connecting lug plate), this product features a thread-adjustable design with a length adjustment range of ±200mm, enabling on-site correction of bracing length errors and structural alignment deviations (perpendicularity error ≤3mm/m). The connecting lug plate is forged for enhanced load-bearing capacity (shear strength ≥345MPa) and welded with stiffeners to prevent local deformation, while the 40Cr alloy steel screw (hardness HRC 30-35) offers high strength and wear resistance, ensuring stable adjustment without thread damage. The node is equipped with a locking nut (10.9 grade) to fix the adjusted length, preventing loosening under dynamic loads (wind, seismic action). The surface is treated with hot-dip galvanizing (zinc layer thickness ≥85μm) for corrosion resistance, adapting to indoor, outdoor, and industrial environments. It is compatible with cross bracing, diagonal bracing, and lateral bracing systems, suitable for large-span steel structures, prefabricated buildings, temporary facilities, and bridge bracing. Installation requires only a wrench for length adjustment and locking, no special equipment, and the modular design supports quick assembly with bracing members (H-beam, angle steel, pipe). The product complies with GB 50017-2017 steel structure design standards and undergoes load testing (bearing capacity ≥500kN for standard models), ensuring reliability in heavy-load scenarios. Professional services include bracing length calculation, adjustment range customization, and on-site alignment guidance, helping customers achieve precise and stable bracing system installation.

Applications
Adjustable Bracing Nodes are versatile and precision-focused components widely used in steel bracing systems for construction and infrastructure projects. Certified by GB 50017-2017 and ISO 9001, they meet strict structural standards, ensuring reliable performance in alignment-critical scenarios. These nodes are suitable for diverse applications, including large-span steel structure bracing (stadiums, exhibition centers, airport terminals), prefabricated building lateral bracing systems, temporary construction facilities (construction sheds, event venues), bridge bracing and reinforcement, industrial workshop steel frame bracing, and seismic retrofitting of existing structures. They are particularly ideal for projects where on-site adjustment is required due to manufacturing tolerances or construction deviations, such as modular steel structures and large-span truss systems. The minimum order quantity is 5 sets for standard specifications (adjustment range ±200mm, compatible with bracing section ≤150×150mm), and customized solutions are available for adjustment range (±100mm to ±300mm), load capacity (up to 1000kN), and material upgrades (stainless steel 316L for corrosion-prone environments) to meet specific project needs. Competitive pricing and bulk purchase discounts (for orders over 50 sets) enhance cost-effectiveness, while the delivery time (5-10 workdays for standard orders) supports construction schedules. With a monthly supply capacity of 800 sets, the manufacturer ensures timely delivery even for large-scale projects. The 40Cr alloy steel and Q355B steel materials, combined with hot-dip galvanizing treatment, ensure durability in indoor, outdoor, and industrial environments, from urban construction sites to coastal bridge projects. Customization options also include high-seismic grade optimization (up to 9 degrees) for earthquake-prone areas and anti-corrosion coating upgrades (fluorocarbon paint) for harsh industrial zones. Whether it's for new bracing system installation or old structure adjustment, the Adjustable Bracing Node delivers flexible and precise performance.
