Contact usMasterful Fastening · The Foundation of Architecture
Anti-Vibration & Anti-Loosening, Fully Traceable
Passed Junker vibration test to ensure zero loosening under earthquakes and wind loads. Compliant with ISO 898-1 high-strength standards, with full material traceability to meet strict project acceptance requirements.
Superior Corrosion Resistance, Extended Service Life
Offers hot-dip galvanizing, Dacromet, stainless steel (304/316), etc. Salt spray test exceeds 1,000 hours, supporting a 50-year building design life and significantly reducing long-term maintenance costs.
Customized Non-Standard Solutions, Precise Adaptation
Supports “drawing-to-production” manufacturing. Provides specialized fasteners for steel structures, curtain walls, pipe galleries, PC components, and other critical joints, with material compatibility to prevent galvanic corrosion.
Faster Installation, Lean Delivery
Optimized drill point design enables self-drilling and self-tapping, reducing pre-drilling steps and increasing installation efficiency by over 30%. Supports project-based packaging and JIT supply to minimize on-site waste and inventory.
