Corporate profile


We have focused on the sales of special steel from the establishment of our company in 1924 to acquire reliability for the customer.

Based on the knowledge and experience accumulated over many years, we approached the project of the method for bonding different metals, friction welding, in 1980, and have fortunately achieved a good reputation from the viewpoint of cost reduction and material saving.

In addition, since friction welding is suitable for environmental protection, participation in different fields can be expected; thus, we are now steadily advancing with this technology as our main business. The purposes of special steel sales and the friction welding business are not only to obtain profit but also contribute to society through customers. We are proud of this concept and will make best efforts continually.

We thank you for your patronage so far and hope you will continue to support and advise us.

President Yuichiro Shimizu
