Our modular single seam expansion joint is engineered for unparalleled durability, comfort, and reliability. Its ultra-low structural height makes it the perfect choice for both refurbishing aged bridge expansion devices and constructing new bridges. The joint is adept at accommodating expansion and contraction ranges from 20mm to 120mm, available in standard variations such as C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. This innovative solution is available in primary structural configurations: C type, RG type, F type, Z type, E type, and M type, each designed to meet the diverse needs of modern infrastructure.
Introducing the RG type bridge expansion joint, a pinnacle of modern engineering for highway bridge construction in China. Crafted from overall hot-rolled 16Mn special-shaped steel, the GQF-RG type surpasses advanced international standards in both technical performance and specifications. Exclusively designed with unique structural types and special-shaped steel rolling in China, it is poised to be a recommended product under transportation industry standards. Key features include a minimal building height and domestically hot-rolled integral formed irregular steel at just 50mm. Ideal for bridges with deck pavement thicknesses of 80mm or more and an expansion capacity of up to 80mm, it facilitates seamless replacement of old expansion devices and excels in new bridge constructions.
The RG type bridge expansion device's rubber sealing strip is crafted to meet rigorous technical standards. Devices featuring chloroprene rubber (CR) sealing tapes are optimized for temperatures ranging from -25 ºC to +60 ºC. For regions experiencing more extreme conditions, natural rubber (NR) sealing tapes are ideal, withstanding temperatures from -40 ºC to +60 ºC. These specifications ensure that the expansion device performs reliably in various climates.
