We source and supply a wide range of steel plates from overseas
Currently, most steel plates distributed in Japan rely on a limited number of importers. However, as supply can be easily affected by tariffs and global conditions, more customers are exploring procurement from other countries to ensure greater supply stability.
At M-Prom, we maintain our own sourcing networks not only in South Korea and China, but also in other overseas markets. This allows us to propose alternative products that offer strong advantages in both quality and price. We support our customers in building the most effective procurement strategy with stable supply as a priority.
