Join the 8th China International Hot Dip Galvanizing Symposium & Exhibition to stay at the forefront of your business!
The biennial China International Hot Dip Galvanizing Conference and Exhibition is one of the most influential hot dip galvanizing conferences in the world. The 2025 International Hot Dip Galvanizing Conference & Exhibition will be held in Changsha, Hunan Province, China from September 22-25, 2025.
The conference will be complemented by an exhibition of international equipment and service suppliers, galvanizing production lines and key zinc alloy production plant visits and networking opportunities.
The program will gather global industry elites, academics as well as representatives of industry associations, public and private institutions.to conduct in-depth exchanges on cutting-edge technologies, market trends, and development strategies. It will also promote technological innovation and the application of new technologies for both general galvanizing and continuous galvanizing products, thereby improving the performance and reducing production costs of their products and meeting the market's diverse needs. At the same time, it provides a stage for IZA members and exhibitors to showcase their corporate strength and technological advantages and expand business cooperation and collaboration among conference attendees.
Simultaneous interpretation in Chinese-English will be available throughout the sessions.
