We are not just a company that "supplies" products. "What is the most important thing for those who pass through this door?" "After passing through, where will they head next?" We are a company that maximizes the combination of departments and proposes even the "nature of space" starting from the door. For example, we engage in proposal-based sales activities that include flow line planning. We offer high-quality products with excellent cost performance. We have a robust international sales and service system. And we provide meticulous and reliable maintenance. All of these come together to assist our customers in creating comfortable spaces. In the future, we will focus on developing barrier-free products in anticipation of an aging society, providing comfortable door spaces in a wider range of scenes.
