Company information
Dandori Vis Co., Ltd. manufactures and sells original construction hardware, screws, and resin products used in new housing and renovations. The name "Dandori Vis" comes from a term used in the construction industry, "Dandori Hachibu, Shigoto Nibun," which emphasizes the importance of planning and efficiency. Since its founding, we have focused on selling convenient and innovative products to construction professionals and have prioritized the development of products that enhance efficiency on construction sites ahead of our competitors. In recent years, there has been a demand for shorter construction processes and reduced labor, and as the workforce of craftsmen is rapidly aging, there is a tendency for the lifespan of products demanded by the market to shorten. We believe it is our mission to quickly respond to changing construction methods and deliver the products developed by Dandori Vis (fresh information) to craftsmen, thereby contributing to the creation of comfortable living spaces. Thanks to the tireless efforts of our founders, including participation in national exhibitions, Dandori Vis has surprisingly high recognition among construction professionals. We offer a unique sales approach with a diverse range of over 18,000 original products. We continue to cherish the tradition of manufacturing and business that we have adhered to since our founding, striving to develop products that will impress our customers, challenging ourselves alongside our employees, and continuously contributing to our customers and society.
