High-Rise Building Steel Structure Fastening Solution

　　Engineering Pain Points: High-rise building steel columns and beams bear heavy loads and must withstand wind vibration, earthquakes, and other loads. This places extremely high demands on the strength, seismic resistance, and fatigue resistance of fasteners, as well as stringent requirements for node connection precision.
　　Compatible Core Products: 10.9S large hexagonal high-strength bolt assemblies, 10.9S torque-shear type high-strength bolts, Grade 10 matching nuts, steel structure washers, hot-dip galvanized anti-corrosion fasteners
　　Solution Advantages: Carefully selected 10.9S high-strength core components with tensile strength ≥1040MPa and stable friction coefficient, fully meeting the stress safety requirements of high-rise main structures; providing torque calculation and node installation guidance throughout the entire process; complete third-party testing reports, complying with national/international standards; supporting non-standard customized irregular node fasteners for precise matching of project designs.
　　Suitable Scenarios: Super high-rise office buildings, mixed-use commercial and residential complexes, and landmark high-rise building steel structure main body connections.

Industrial Plant & Warehousing Logistics Steel Structure Fastening Solution

　　Project Pain Points: Plants/warehouses are mostly large-span steel structures, subject to crane loads and equipment vibration, requiring high strength, anti-loosening 　　　　properties, and corrosion resistance in fasteners, while also demanding high construction efficiency and short delivery cycles.
　　Compatible Core Products: 10.9S high-strength bolts, 8.8 grade secondary structural connectors, anchor bolts, hot-dip galvanized anti-corrosion fasteners, roof waterproofing self-drilling screws, and a complete set of connectors for the enclosure system.
　　Solution Advantages: One-stop supply of primary and secondary structural fasteners; 10.9S high-strength components ensure safety in main load-bearing parts, while 8.8 grade connectors control costs in secondary structures; anti-corrosion coatings are selected as needed, with hot-dip galvanizing for ordinary plants and Dacromet for long-lasting corrosion protection in chemical/coastal plants; bulk on-demand supply is supported to meet the supply needs of rapid plant construction.
　　Suitable Scenarios: Light and heavy industrial plants, steel structure warehouses, logistics parks, and industrial park steel structure projects.

Steel-Concrete Composite Structure Fastening Solution

　　Engineering Pain Points: Steel-concrete composite structures (such as floor slabs and beam-column joints) require a balance between the strength of the steel structure and the load-bearing capacity of the concrete. Welded fasteners must ensure weld strength, eliminating incomplete welds and leaks, placing stringent requirements on product materials and welding processes.
　　Compatible Core Products: Cylindrical head weld studs + matching ceramic rings, 10.9 grade fully threaded studs, high-strength anchor bolts
　　Solution Advantages: Weld studs are made from high-quality base materials, and matching ceramic rings ensure aesthetically pleasing welds with high strength, conforming to ISO13918/GB10433 standards; welding process guidance is provided to avoid welding defects; stud products are precisely matched to the stress requirements of steel-concrete joints, eliminating the risk of loosening.
　　Suitable Scenarios: Steel structure factory crane beams, floor slabs, steel-concrete beam-column joints, and steel-concrete transition sections of bridges.

Bridge & Transportation Hub Steel Structure Fastening Solutions

　　Project Pain Points: Bridges, airports, high-speed rail stations, and other transportation hubs are constantly subjected to dynamic loads, fatigue loads, and harsh outdoor weather conditions. Fasteners must possess fatigue resistance, high weather resistance, and long-term corrosion protection, demanding the highest levels of durability and stability.
　　Compatible Core Products: 10.9S high-strength bolt assemblies, large-size anchor bolts, fatigue-resistant weld studs, hot-dip galvanized + sealed coating anti-corrosion fasteners, and hoisting rigging.
　　Solution Advantages: Manufactured using fatigue-resistant special steel, bolt torque coefficient is precise, weather-resistant anti-corrosion coating thickness meets standards, resisting outdoor rain and salt spray corrosion; all product categories meet bridge engineering standards, with complete testing reports; long-term warranty is provided, ensuring worry-free after-sales service.
　　Suitable Scenarios: Highway/railway bridges, airport terminals, high-speed rail stations, and transportation hub steel structure projects.
