Audited Supplier Discover the unparalleled durability, comfort, and reliability of our modular single seam expansion joints. With an impressively low structural height, these joints are the perfect solution for both the renovation of aging bridge expansion devices and the construction of new bridges. Offering an allowable expansion and contraction range of 20-120mm, our joints come in various models including C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. The primary structural forms available are C type, RG type, F type, Z type, E type, and M type.
Experience innovation with our RG type bridge expansion joint device, a pioneering solution for highway bridge construction in China. This device features an overall hot-rolled 16Mn special-shaped steel, elevating its comprehensive technical performance and indicators to surpass international standards. Its structural form and hot-rolled special-shaped steel are groundbreaking in China, setting it as a recommended product in the transportation industry standard. Key features include a low building height with domestically produced hot-rolled integral formed irregular steel standing at only 50mm. Perfectly suited for bridges with deck pavement thicknesses of 80mm or more and expansion amounts up to 80mm, it also facilitates the replacement of old expansion devices and is ideal for new bridge constructions.
Our RG type bridge expansion device also boasts stringent technical requirements for its central rubber sealing strip. When using chloroprene rubber (CR) sealing tape, the device performs optimally in temperatures ranging from -25 ºC to +60 ºC. For regions with more extreme conditions, natural rubber (NR) sealing tape ensures reliability in temperatures from -40 ºC to +60 ºC.
