The modular single seam expansion joint redefines durability, comfort, and reliability. Boasting a low structural height, it's the go-to choice for both renovating aged bridge expansion devices and constructing new bridges. With an impressive expansion and contraction range of 20-120mm, our product spectrum includes models such as C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. The primary structural configurations are C type, RG type, F type, Z type, E type, and M type.
Introducing the RG type bridge expansion joint device, a premier solution tailored for highway bridge construction in China. Crafted from hot-rolled 16Mn special-shaped steel, the GQF-RG type excels with technical performance metrics that match or exceed global standards. Its pioneering structural design and steel composition are unparalleled domestically, earning it high recommendations. Notable features include a minimal building height of just 50mm, achieved with integrally formed hot-rolled steel. Ideal for bridges with a deck pavement thickness of 80mm or more and an expansion capacity of up to 80mm, it effortlessly replaces old expansion devices and supports new bridge construction.
The RG type bridge expansion device is equipped with rubber sealing strips that adhere to stringent technical standards. Devices using chloroprene rubber (CR) sealing tapes are perfect for environments with temperatures ranging from -25°C to +60°C. Meanwhile, those utilizing natural rubber (NR) sealing tapes are engineered for regions with temperatures between -40°C and +60°C.
