The modular single seam bridge expansion joint sets an industry standard for durability, comfort, and reliability. With its low structural height, it is perfect for both the renovation of existing bridge expansion devices and the construction of new bridges. It can accommodate an extensive expansion and contraction range from 20-120mm, supporting models such as C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. The primary structural types available include C type, RG type, F type, Z type, E type, and M type, ensuring versatility and adaptability for any engineering requirement.
The RG type bridge expansion joint device is a revolutionary advancement in highway bridge construction in China, crafted from hot-rolled 16Mn special-shaped steel. The GQF-RG type not only sets new benchmarks in technical performance and innovation but often surpasses international standards. With an ultra-low height of just 50mm, it is an ideal solution for bridges with a deck pavement thickness of 80mm or more, accommodating an expansion amount of up to 80mm. This device simplifies the replacement of outdated expansion devices and is also perfect for new bridge construction. Recognized as a recommended product in the transportation industry, its unique rolling technology and structural design make it a pioneering feature in China's bridge engineering landscape.
The rubber sealing strip of the RG type bridge expansion device adheres to stringent requirements: chloroprene rubber (CR) sealing tape is ideal for regions with temperatures ranging from -25 ºC to +60 ºC. For areas experiencing temperatures between -40 ºC and +60 ºC, natural rubber (NR) sealing tape is the optimal choice.
