Our modular single seam expansion joints offer unparalleled durability, comfort, and reliability. Their compact structural height makes them perfect for both renovating aging bridge expansion devices and constructing new bridges. With an adaptable range of expansions and contractions from 20-120mm, we provide a variety of models including C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. Our designs encompass versatile structural forms such as C type, RG type, F type, Z type, E type, and M type, ensuring they meet diverse bridge construction requirements with ease and flexibility.
The RG type bridge expansion joint device signifies a significant advancement in China's bridge construction technology, especially designed for highway bridge projects. Featuring overall hot-rolled 16Mn special-shaped steel, the RG type expansion device delivers technical performance that aligns with or surpasses global standards. Its pioneering structural design and special-shaped steel rolling position it as the upcoming industry benchmark. Key attributes include a minimal building height of only 50mm and the use of domestically produced, hot-rolled irregular steel. It suits bridges with a deck pavement thickness of 80mm or more, accommodating expansions up to 80mm. This makes it perfect for both replacing outdated expansion devices and facilitating new bridge constructions efficiently.
The RG type bridge expansion device's rubber sealing strip adheres to the highest technical standards. Employing chloroprene rubber (CR) sealing tape, it is perfect for areas with temperatures ranging from -25ºC to +60ºC. Alternatively, natural rubber (NR) sealing tape suits regions with temperatures from -40ºC to +60ºC, guaranteeing optimal performance in a variety of climatic conditions.
