Our modular single seam expansion joint is the epitome of durability, comfort, and reliability, making it the ideal choice for both upgrading older bridge expansion devices and constructing new bridges. Boasting a minimal structural height, this expansion joint is extraordinarily versatile. It offers an impressive expansion and contraction range from 20-120mm, adapting effortlessly to various structural forms such as C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, RG80. Discover its main structural configurations: C type, RG type, F type, Z type, E type, and M type, each designed to cater to specific engineering requirements.
The RG type bridge expansion joint device is a groundbreaking solution for highway bridge construction in China. Crafted from overall hot-rolled 16Mn special-shaped steel, it delivers superior technical performance that meets or exceeds international standards. Its innovative design and unique special-shaped steel rolling are pioneering in China, making it a highly recommended choice within the transportation industry. Key features include a low building height with domestically produced hot-rolled irregular steel, standing at just 50mm. This joint is ideal for bridges with a deck pavement thickness of 80mm or more and an expansion capacity of up to 80mm, facilitating the easy replacement of old bridge expansion devices and perfectly suited for new bridge construction.
The RG type bridge expansion device is engineered to meet high-standard technical requirements for the rubber sealing strip. Devices equipped with chloroprene rubber (CR) sealing tape are optimized for temperatures ranging from -25 ºC to +60 ºC, while those with natural rubber (NR) sealing tape are designed for temperature ranges from -40 ºC to +60 ºC. This ensures unwavering performance and reliability across a wide array of environmental conditions.
