Audited Supplier Our modular single seam expansion joint boasts outstanding durability, comfort, and reliability. Thanks to its minimal structural height, it's perfectly suited for renovating old bridge expansion devices and is equally effective for new bridge constructions. With an allowable expansion and contraction range of 20-120mm, it includes various specifications such as C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, RG80. The primary structural types include C type, RG type, F type, Z type, E type, and M type.
The RG type bridge expansion joint device represents a groundbreaking innovation for highway bridge construction in China. Utilizing an overall hot-rolled 16Mn special-shaped steel, the GQF-RG type device meets or surpasses the advanced technical standards of similar international products. This innovative design and special-shaped steel rolling are unique to China, making it a recommended product in the transportation industry. Key features include a low building height of just 50mm and a hot-rolled, integrally formed irregular steel. It is ideal for bridges with deck pavement thicknesses of 80mm or more and expansion amounts up to 80mm. This device simplifies replacing old bridge expansion devices and can be easily integrated into new constructions.
The RG type bridge expansion device's rubber sealing strip requirements are as follows: Devices using chloroprene rubber (CR) sealing tape are suitable for temperatures ranging from -25 ºC to +60 ºC. Those using natural rubber (NR) sealing tape are effective in areas with temperatures between -40 ºC to +60 ºC.
