1. Anti slip bearing capacity ensures that the scaffold will not experience displacement and sliding between steel pipes under dynamic loads such as construction personnel walking and material stacking 2. Reliable locking, with no breakage of the fastener body, no slipping of the bolts, and the ability to maintain a locked state for a long time; 3. High resistance to damage, high resistance to deformation, and excellent tensile performance of docking fasteners 4. Easy installation, the rotating fastener can flexibly adjust the angle of the diagonal rod, adapting to the needs of different inclination angles of the tie; 5. The material has high strength and corrosion resistance, and is suitable for construction sites where corrosive media exist such as rainwater, cement slurry, and dust; 6. Anti aging and wear-resistant, high-strength steel, with phosphating and galvanizing treatment on the surface, resistant to wear and corrosion in long-term use, without cracks, deformation and bolt slip; The inner wall of the "U-shaped" groove where the fastener contacts the steel pipe should be smooth and free of burrs to avoid scratching the steel pipe or exacerbating its own wear during installation. 7. Scene and environmental adaptability: Adapt to the type, load level, and environmental conditions of scaffolding, such as coastal humid areas and high-temperature work scenarios (such as welding work areas)
