Bolt Connected Steel Structure Warehouse — 10.9 Grade High-Strength Quick Assembly

The Bolt Connected Steel Structure Warehouse revolutionizes on-site construction with a fully bolted assembly system using ISO 4014 and ISO 4017 certified 10.9-grade high-strength torque-shear bolts. All steel components arrive at the job site with pre-drilled precision bolt holes, eliminating the need for heavy on-site welding and reducing total installation time by 30-50% compared to traditional welded structures.

Bolt Connection Advantages

• Rapid On-Site Assembly: Pre-drilled components with numbered bolt hole patterns enable fast, foolproof assembly. No welding equipment, certified welders, or weather-dependent welding conditions required — just bolt and torque.
• 10.9-Grade High-Strength Bolts: Premium torque-shear bolts (TSBs) with guaranteed tensile strength ≥1000 MPa and yield strength ≥900 MPa. The spline-end shears off at the design torque, providing visual verification of correct bolt tension — no torque wrench calibration needed.
• Superior Seismic Performance: Bolted connections provide controlled ductility during seismic events. Unlike brittle welded joints, bolted connections can dissipate earthquake energy through controlled slip, protecting the main structural members from catastrophic failure.
• Easy Future Expansion: Bolt-connected structures can be disassembled, relocated, or expanded with minimal effort. Additional bays can be bolted on without cutting or welding existing steelwork.
• Quality Assurance: Every bolt is factory-tested and certified. On-site inspection is simple — visually confirm the sheared spline end on every TSB. No ultrasonic or radiographic weld testing required.

Technical Specifications

Ideal For

Remote location projects with limited welding access, fast-track construction schedules, seismic zones requiring ductile connections, temporary or relocatable warehouses, and projects where future expansion is anticipated.
