Watch as we walk through the full process, from initial setup to real-world testing. In this video, we demonstrate the production and quality control of our ID 508mm / 610mm PPGI coils, manufactured to JIS standards with zinc coatings ranging from 40g/m² to 275g/m². See how these high-performance metal materials are tested for durability and corrosion resistance, ensuring they meet the rigorous demands of industrial applications.
