To effectively mitigate the impact of water level fluctuations from the upper reaches of the Lanjiang River on coastal areas, the flood control cofferdam project constructed on a tributary of the Lanjiang River in Mabu Subdistrict, Lanxi City, has adopted our high-performance flood panel system. This system, featuring 1-meter high panels with each unit covering 4.5 square meters, is constructed from 5 cm thick aluminum alloy with a 2 wall thickness. Through its modular sealing structure, the product achieves precise water level control, forming an adjustable flood barrier that significantly enhances the region’s disaster prevention and mitigation capabilities.
