Discover the future of bridge construction with our RG Type Bridge Expansion Joint Device. Engineered for highway bridges in China, this device features an overall hot-rolled 16Mn special-shaped steel, achieving or surpassing international standards. Innovative in both structural design and special-shaped steel rolling, the RG type is set to become a benchmark in the transportation industry. Key features include a low building height of just 50mm, making it suitable for bridges with deck pavement thicknesses of 80mm or more and expansion amounts of 80mm or less. Ideal for replacing old expansion devices as well as new bridge construction, this product offers unparalleled convenience and efficiency.
The RG Type Bridge Expansion Device sets a high bar for technical excellence, especially with its rubber sealing strips. Using chloroprene rubber (CR) sealing tape, it is perfect for temperatures ranging from -25ºC to +60ºC. For even colder climates, our natural rubber (NR) sealing tape performs flawlessly in temperatures from -40ºC to +60ºC, making this expansion device adaptable to a broad range of environmental conditions.
