The modular single seam of our Rubber Bridge Expansion Joint showcases exceptional durability, unparalleled comfort, and steadfast reliability. With its minimal structural height, it serves as the perfect solution for both the renovation of aging bridge expansion devices and the construction of new bridges. Engineered to accommodate an expansive range of 20-120mm for expansion and contraction, our product is available in the following versatile models: C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, RG80. The primary structural formats include C type, RG type, F type, Z type, E type, and M type, ensuring seamless adaptability to a variety of bridge designs.
The RG type bridge expansion joint device stands at the forefront of innovation in China's highway bridge construction industry. Composed of hot-rolled 16Mn special-shaped steel, the GQF-RG type bridge expansion device offers superior technical performance, meeting and exceeding international standards. Its unique structural design and innovative rolling of special-shaped steel have earned it a top recommendation in the transportation sector. Key features of the RG type expansion device include a low building height and an integrally formed irregular steel, standing at only 50mm high. This makes it ideal for bridges with deck pavement thicknesses of 80mm or more, and expansion needs of up to 80mm. This state-of-the-art device simplifies the replacement process of old expansion joints and is equally suitable for new bridge constructions.
The RG type bridge expansion device is meticulously engineered with stringent technical requirements for its rubber sealing strip. The chloroprene rubber (CR) sealing tape variant is optimal for regions experiencing temperatures from -25ºC to +60ºC. Alternatively, the natural rubber (NR) sealing tape variant excels in temperatures ranging from -40ºC to +60ºC. These specifications ensure the device's reliability and longevity across a wide range of environmental conditions.
