The modular single seam design of our ISO9001-2008 Certified Expansion Joint is crafted to deliver unmatched durability, comfort, and reliability. Featuring a reduced structural height, it is the premier solution for both restoring old bridge expansion joints and constructing new bridges. This product accommodates an expansion and contraction range from 20 to 120mm, and is available in a variety of types including C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. The primary structural forms encompass C type, RG type, F type, Z type, E type, and M type.
The RG type bridge expansion joint device, specifically engineered for highway bridge construction in China, exemplifies state-of-the-art innovation. Constructed using overall hot-rolled 16Mn special-shaped steel, the GQF-RG type meets or exceeds the most stringent international standards. This revolutionary product, with its advanced structural design and special steel rolling, is poised to set a new benchmark in the transportation sector. Key features include a remarkably low building height and the use of domestically produced, hot-rolled, integral formed irregular steel standing at just 50mm high. It is the optimal solution for bridges with deck pavement thickness of 80mm or more and expansion requirements of 80mm or less, making it ideal for both replacing outdated joints and new installations.
The RG type bridge expansion device boasts a rubber sealing strip engineered to stringent technical specifications. Devices featuring chloroprene rubber (CR) sealing tape are effective in temperatures ranging from -25ºC to +60ºC, while those using natural rubber (NR) sealing tape are capable of withstanding temperatures from -40ºC to +60ºC. This ensures adaptability and resilience across a diverse range of environmental conditions.
