Structural members that combine the workability of wood and the strength of steel. They contribute to the creation of large spaces and the rationalization of design without the use of special construction methods.

The wooden hybrid structural member "TN-WOLSH Series" combines the workability of wood with the strength of steel, allowing for the creation of large spaces without the need for special construction methods, contributing to reduced design loads and streamlined construction processes. By using steel and wood in appropriate locations, it is possible to enhance structural strength while maintaining the workability of wood. The development of dedicated examination sheets and structural data facilitates smooth progress from structural calculations to precut CAD integration. The combination of beams and shear walls enables large space design based on general design knowledge, contributing to improved design efficiency and reduced burden for the introduction of non-residential wooden structures. 【Features】 ■ Hybrid structure that integrates wood and steel ■ Use of steel and wood in appropriate locations while maintaining the workability of wood ■ Fusion of the excellent strength and toughness of steel with the existing wooden design and construction methods ■ Capability to create large spaces without using special construction methods ■ Support for data preparation necessary for structural calculations and CAD integration ■ Lineup includes "TN-WOLSH Beam" and "TN-WOLSH Burring Wall" *For more details, please refer to the materials. Feel free to contact us with any inquiries.

We are a manufacturer of construction hardware that firmly protects the "wooden houses" loved by the Japanese from earthquakes. We were the first in Japan to promote the Kuretec hardware method, making traditional wooden frame construction even more robust. Additionally, we boast the highest production volume in Japan for reinforcing hardware (Z-mark, C-mark) traditionally used in wooden house construction. Furthermore, our precut business for structural frames using the latest equipment is set to expand throughout the entire eastern Japan in the future. We have group companies in Tochigi Prefecture and Chiba Prefecture in Japan, as well as in China and Guam overseas, aiming for future development into a global company.
