Product Description

Product Description

 

The modular single seam from Suzhou Xinyu New Material Technology Co., Ltd. redefines durability, comfort, and reliability. With its minimal structural height, it is the ideal choice for renovating old bridge expansion devices and constructing new bridges. This advanced modular expansion joint design accommodates an expansion and contraction range of 20-120mm. Available in various types such as C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, RG80, and the primary structural forms include C type, RG type, F type, Z type, E type, and M type.
The RG type bridge expansion joint device, a cutting-edge innovation for highway bridge construction in China, features an overall hot-rolled 16Mn special-shaped steel. The GQF-RG type bridge expansion device's technical performance and specifications exceed international standards. This domestically innovative product, with its unique structural type and special-shaped steel rolling, is set to become the industry standard. Key features include a low building height with hot-rolled integral formed irregular steel standing at just 50mm. Suitable for bridges with a deck pavement thickness of 80mm or more and an expansion amount of 80mm or less, it facilitates both the replacement of old expansion devices and new bridge construction.
The RG type bridge expansion device's rubber sealing strip adheres to rigorous technical requirements: for chloroprene rubber (CR) sealing rubber tape, it is suitable for regions with temperatures ranging from -25 ºC to +60 ºC. For natural rubber (NR) sealing rubber tape, it is ideal for areas with temperature variations between -40 ºC and +60 ºC.
