Company information
Since its establishment, we have sold product materials including duct manufacturing machines, spiral ducts, and insulated flexible ducts. We have one of the largest service networks in the industry with 35 locations domestically and internationally. Since 2000, we have proposed improvements in on-site work with new materials such as "FEF," an insulation material, and new methods like "Patchin Lock." In 2020, we developed the industry's first fiber laser cutting machine. We are also progressing in collaboration with BIM to realize CAD/CAM. In 2022, we sold "air curtains" (manufactured by FRICO in Sweden), which hold a 60% share of the global market.
