Double fasteners (right angle fasteners) have become the core components of complex scaffold configurations due to their multi-directional connection ability. The new double fastener that complies with EN74 Class B and BS1139 standards adopts a 48.3mm standard pipe diameter adaptation design, which can achieve a 90 ° vertical connection between the horizontal bar and the vertical pole and can be adjusted at any angle. Its innovative double clamp structure controls the error within 0.2mm through precision forging technology, and with the help of BIM pre assembly data, improves the docking accuracy of components in prefabricated construction by 60%.

  In a chemical industrial park project in Southeast Asia, the double fastener demonstrated strong environmental adaptability: its impact toughness remained above 80J at -40 ℃, far exceeding the industry average of 30J for traditional components; The adaptive design of mechanized installation equipment has doubled its installation efficiency, and a team of 10 people can complete 300 sets of scaffolding construction in a single day. The hot-dip galvanizing surface treatment process ensures a service life of more than 10 years in high temperature and high humidity environments, which is 60% longer than ordinary fasteners.
