Our modular single-seam expansion joints are the epitome of durability, comfort, and reliability, making them perfect for both renovation projects and new bridge constructions. These joints boast a low structural height, allowing seamless integration into existing expansion systems while offering robust solutions for new builds. They cater to expansion and contraction from 20-120mm and come in a variety of models: C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. The primary structural configurations include C type, RG type, F type, Z type, E type, and M type, each meticulously crafted to meet a wide range of engineering requirements.
The RG type bridge expansion joint device is a hallmark of innovation in bridge engineering, specifically tailored for highway bridge construction in China. Made from hot-rolled 16Mn special-shaped steel, this device showcases exceptional technical performance, meeting or exceeding international standards. Its unique structure and rolling process exemplify domestic engineering excellence. Key features include an impressively low building height of just 50mm and the use of domestically produced, hot-rolled, integrally formed irregular steel. Ideal for bridges with deck pavement thicknesses of 80mm or more and expansion needs up to 80mm, this device simplifies the replacement of old expansion joints and is equally effective for new bridge construction.
The technical specifications for the rubber sealing strip in the RG type bridge expansion device are meticulously designed to ensure top performance. For regions with temperatures ranging from -25ºC to +60ºC, the device uses chloroprene rubber (CR) sealing tapes. In colder climates, with temperatures between -40ºC and +60ºC, natural rubber (NR) sealing tapes are employed. Each type is engineered to withstand the specific demands of its environment, ensuring longevity and reliability.
