GT-Flex, which combine the rigid anchorage of modular joint and noise reduction of finger joint, is an innovative and patented product. Comparing to the modular joints, these joints can significantly reduce the noise up to 5dB (A), and comparing to finger joints, these joints can provide a more reliable anchorage which can prolong the working life about 10 years.

GT-Flex Finger Joint has been certified by China Highway and Transportation Society (CHTS) in 2014, with a conclusion “Reach international standard and recommend to form industry standard with the Ministry of Transport”. In 2015, stemmed from GT-Flex, a standard named “Integrated anchorage expansion and contraction installation” passed the preliminary review as a sub-segment of Chinese MOT National Standard. And in the same year, this technology was selected into the directory of scientific and technological achievements of Chinese MOT and earned the subsidies from Chinese MOF.
