Tinplate (commonly known as Makou board metal) is made by electroplating tin onto a thin, pressable steel substrate. To ensure consistency and stability between material batches, our raw materials are specially custom-ordered from Baosteel, featuring industrial-grade highest standards in surface flatness, roughness, etc. Common board thicknesses: 0.2, 0.28, 0.4, 0.5, 0.8 (unit: mm).
