Supply of Beijing Bridge Expansion Joint Quotation

**Bridge Expansion Joint** The bridge expansion joint refers to the expansion joints set between the ends of two beams, between the beam ends and the bridge abutment, or at the hinge positions of the bridge, to accommodate the deformation of the bridge deck. The expansion joint is required to expand and contract freely in both parallel and vertical directions to the bridge axis, to be secure and reliable, and to ensure a smooth passage for vehicles without bumps or noise. It should also prevent rainwater and debris from entering and blocking it. Installation, inspection, maintenance, and cleaning should be easy and convenient. At the location of the expansion joint, the railing and bridge deck pavement should be disconnected. **GQF-C Expansion Joint** The GQF-C type bridge expansion joint device is a new type of bridge expansion joint device suitable for highway bridge construction in China. The GQF-C type bridge expansion joint device uses integral hot-rolled 16Mn shaped steel, overcoming the characteristics of poor linearity and uneven assembly dimensions of extruded shaped steel. The comprehensive technical performance and technical indicators of the GQF-C type bridge expansion joint device meet or exceed the advanced level of similar international products. The structural form and shaped steel rolling are both pioneering in the country and are expected to become a recommended product in the transportation industry standards. There is a market demand in Beijing, and this industry is a key focus of national standards in today's society.
