Masteel completed the hot load test run of its sixth hot-dip galvanizing line in December 2025. The successful testing validates equipment functionality, process parameters, & product quality before commercial production begins. Hot-dip galvanizing involves immersing cold-rolled steel in molten zinc baths at 460°C, creating corrosion-resistant coatings. The expansion positions Masteel to serve growing demand across construction, automotive, & appliance sectors. Modern galvanizing lines typically possess annual capacities between 300,000 to 600,000 metric tons.
