Product Description

Product Description

 

The Modular Single Seam Bridge Expansion Joint stands out due to its exceptional durability, comfort, and reliability. Its low structural height makes it an ideal choice for the refurbishment of aging bridge expansion systems as well as new bridge constructions. This versatile joint accommodates expansion and contraction from 20-120mm, with standard models including C40, C60, C80, D40, D60, D80, D100, D120, RG40, RG60, and RG80. The primary structural configurations available are C type, RG type, F type, Z type, E type, and M type.
Introducing the RG Type Bridge Expansion Joint, a cutting-edge solution tailored for highway bridge construction in China. This ground-breaking device is crafted from hot-rolled 16Mn special-shaped steel, ensuring superior performance and reliability. The GQF-RG type bridge expansion device boasts technical specifications that meet or surpass international standards. Its unique structural design and innovative steel rolling are firsts in China, making it a recommended product for transport industry standards. Key features include a minimal construction height and domestically produced, integrally formed irregular steel with a height of just 50mm. This device is perfect for bridges with deck pavement thicknesses of 80mm or more and an expansion capacity of up to 80mm. It is ideal for both replacing outdated expansion joints and new bridge projects.
The RG Type Bridge Expansion Device's rubber sealing strips are held to rigorous specifications. Devices using chloroprene rubber (CR) seals are designed for regions with temperatures ranging from -25ºC to +60ºC. For areas with temperature variation from -40ºC to +60ºC, natural rubber (NR) sealing strips are used. Both options ensure robust performance across diverse environmental conditions.
