Bridge steel structure anti-corrosion engineering case: Huai'an Baima Lake Bridge—— The main girder of Huai'an Baima Bridge adopts fully welded flat streamlined closed steel box girder, which has huge welding volume and easy deformation. These welding points are facing huge challenges in controlling anti-corrosion quality. East China Zinc Shield serves as the overall anti-corrosion solution provider for this project. , For its tailor-made refrigeration zinc spray anti-corrosion system.
