Since our establishment in 1972, we have grown alongside the development of the Japanese economy. We began producing grating as our main product and have contributed to society as a leading company in the industry to this day. During this time, we have also developed new products related to construction and civil engineering beyond grating, including the sluice gate plant business, hot-dip galvanized coating business, shock protector business, bridge steel structure business, water conduit and drainage pipe business, metal processing business related to construction, and exhibition case business for museums and galleries, among others, building a solid foundation and achievements across various industries. Currently, through the deployment of five factories and twelve branches and sales offices across the country, we are involved in a wide range of public works as well as general private sector construction projects. We will continue to accumulate and refine these technologies to meet our customers' needs.
