Steel building materials that have a shorter construction period and lower cost compared to steel frame and RC methods! Panel manufacturing is done in-house, achieving high precision and low cost!
The new construction method "CFS Method" is a highly durable and earthquake-resistant 2x4 steel house. The 2x4 steel house uses galvanized steel sheets, achieving high durability! It has 1.5 times the strength of wooden panels while being more cost-effective than RC and heavy steel structures, offering an excellent balance of quality and price. We can respond to various requests, such as reducing costs and shortening construction periods for RC and steel structures, or introducing the CFS method as an alternative to wood. If you have any questions about the introduction of the CFS method or would like a quote, please feel free to contact us. *Please download the catalog as a PDF or contact us for more information.
