Modular single seam boasts exceptional durability, supreme comfort, and unparalleled reliability. Its low structural height makes it an ideal choice for the renovation of aging bridge expansion devices and equally suitable for constructing new bridges. It accommodates an impressive expansion and contraction range of 20-120mm, typically available in models C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, RG80. The primary structural configurations include C type, RG type, F type, Z type, E type, and M type.
The RG type bridge expansion joint device is a cutting-edge solution tailored for highway bridge construction in China. This innovative device features an overall hot-rolled 16Mn special-shaped steel, delivering superior technical performance and meeting or surpassing the global standards of similar products. The GQF-RG type bridge expansion device offers a unique structural design and special-shaped steel rolling, setting a new benchmark in China. With a low building height and domestically produced hot-rolled integral formed irregular steel standing at just 50mm, it is perfect for bridges with deck pavement thicknesses of 80mm or more and an expansion range up to 80mm. It is not only a convenient replacement for old bridge expansion joints but also an excellent choice for new bridge construction.
The technical specifications for the rubber sealing strip within the RG type bridge expansion device are as follows: Devices using chloroprene rubber (CR) sealing rubber tape are optimal for areas with temperatures ranging from -25 ºC to +60 ºC. Those employing natural rubber (NR) sealing rubber tape are suitable for regions with temperatures spanning from -40 ºC to +60 ºC.
