Applications/Examples of results
In Japan, it is widely used at construction sites of major general contractors and subcontractors, and it has a proven track record as an earthquake wire restraint in various countries around the world. Notably, it has shown significant growth in the United States, Canada, and India. We have obtained basic data through tests conducted in those countries. In Japan, we have conducted necessary tests while receiving strict feedback from the committee members of the Japan Building Center, reported the results, and received certification. <Achievements in Japan> • Large logistics facilities • Large factory facilities • Commercial facility parking lots • Others <Examples of achievements overseas> ★United States • Boeing 737 plant • Caterpillar plant • Amazon • Siemens • Microsoft Columbia Data Center • Pioneer/DuPont Bio Agriculture R&D Lab • Intel • US Veterans Affairs Hospital ★Canada • IKEA • Ottawa Airport • Kitchener West Water Treatment Plant • St. Thomas Elgin General Hospital • Greater Moncton Airport ★India • Boeing Hangar C15 • Mumbai Airport
