Product Description

Product Description

 

Our modular single seam bridge expansion joint stands out for its exceptional durability, unparalleled comfort, and unwavering reliability. With a notably low structural height, it is ideally suited for the refurbishment of aging bridge expansion mechanisms and equally effective for new bridge constructions. This versatile joint accommodates an expansion and contraction range of 20-120mm, with standard models including C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, RG80. The primary structural configurations available are: C type, RG type, F type, Z type, E type, and M type.
The RG type bridge expansion joint device represents a groundbreaking innovation in the realm of highway bridge construction in China. Crafted from an overall hot-rolled 16Mn special-shaped steel, the GQF-RG type bridge expansion device boasts comprehensive technical performance and benchmarks that rival or surpass international standards. Its unique structural format and special-shaped steel rolling are pioneering achievements within China and have earned it a recommended status in the transportation industry standards. Key features of the RG type bridge expansion device include its minimal building height, with domestically produced hot-rolled integral formed irregular steel standing at a mere 50mm. This device is compatible with various bridges, particularly those with a bridge deck pavement thickness of 80mm or more and an expansion range up to 80mm, offering ease of replacement for old expansion devices and applicability in new bridge construction projects.
The technical specifications for the rubber sealing strip at the core of the RG type bridge expansion device are meticulously designed. Utilizing chloroprene rubber (CR) sealing tape, this device is optimized for environments with temperatures ranging from -25 ºC to +60 ºC. Alternatively, natural rubber (NR) sealing tape is available for regions experiencing temperatures between -40 ºC and +60 ºC.
