The development and trial production of high corrosion-resistant products with Zn-Al-Mg coating for photovoltaic applications are carried out after transform Zn-Al-Mg production line of Baotou Steel. The microstructure of coating for Zn-Al-Mg products is analyzed, neutral salt spray test and surface defects of the products with Zn-Al-Mg coating are analyzed, controlled and studied. The analysis results showed that the microstructure of the coating was composed of Zn-rich phase, ternary eutectic phase of Zn/MgZn2/Al and binary eutectic phase of Zn/MgZn2 as well as the elements of Al and Mg were with uniform distribution in the coating; the neutral salt spray test results showed that the products with Zn-Al-Mg coating manufactured by Baotou Steel were with good corrosion resistance, processability, formability and self-healing ability of notch. The trial production results showed that the process control of Zn-Al-Mg production line of Baotou Steel was stable, stable batch productions of products with Zn-Al-Mg coating were realized, qualified rate of products reached 95.33% and yield reached 97.84% so that all performances could meet the technical requirements.
