This type of single fastener is optimized for super high-rise construction scenarios, with a stress dispersion structure around the bolt holes, reducing the concentration factor by 65%. The single point load-bearing capacity can reach 25 tons, which is 67% higher than traditional components. After hot-dip galvanizing treatment on the surface, the salt spray corrosion resistance is increased by 5 times. In harsh environments such as coastal bridges and underground pipe galleries, the corrosion rate is less than 0.1% after 300 days. The actual test of a super high-rise project shows that the scaffold using this fastener has a node displacement of only 1/5 of the design value in a 14 level typhoon simulation test, making it a true “safety anchor”.

    As the core connecting component of the scaffolding system, the structural strength of a single fastener directly determines construction safety. The latest developed integrated forging single fastener has been innovated through three-dimensional forging technology, increasing the tensile strength of traditional castings from 600MPa to 850MPa, a 40% increase. The key breakthrough lies in the use of isothermal forging and waste heat treatment technology, which solves the industry problem of “strength and toughness cannot be achieved simultaneously” – while maintaining high strength, the elongation rate is increased to 18%, which is 2.2 times that of traditional products.
