It is possible to produce high quality at low cost! We are focusing on the production of custom metal fittings for wooden non-residential buildings.
Our company is focusing on the production of custom metal fittings for wooden non-residential buildings, which have seen an increase in demand in recent years. With the rising demand for hybrid structures combining steel and wood, as well as medium to large-scale wooden buildings, the fittings for joints are also becoming larger, leading us to engage in custom production tailored to specific projects. We utilize fiber laser processing machines, machining equipment, and welding machines to carry out all manufacturing in-house, providing comprehensive services from the creation of fitting production drawings to manufacturing, plating, and specified inspections. By maximizing our long-developed metal processing technology and know-how as a precut factory, we can produce high-quality products at low costs. 【Features】 - The fittings for joints are becoming larger, and we conduct custom production tailored to specific projects. - We utilize fiber laser processing machines, machining equipment, and welding machines for all in-house manufacturing. - We provide comprehensive services from the creation of fitting production drawings to manufacturing, plating, and specified inspections. - We maximize our long-developed metal processing technology and know-how as a precut factory. *For more details, please refer to the PDF document or feel free to contact us.*

Optimizing board thickness to achieve high strength! This enables application to a wider range of wooden structures.
"Tech One TCW" is a joining hardware that achieves higher strength while being compact. By fully utilizing the know-how of Nippon Steel Corporation's steel house, we have developed a new hardware that is compact yet has improved load-bearing capacity compared to the conventional Tech One, making it applicable to a wider range of wooden structures. By thinning the wing parts, we optimized the critical and excess areas at the joint, and through a special riveting technique, we were able to simultaneously enhance the strength and compactness of the hardware by joining two pieces together. 【Features】 - A strong framework can be achieved with a simple combination of bolts and drift pins. - By reducing the protrusion compared to Tech One P3 and thinning the plate thickness, we achieved a weight reduction of up to 40%. - By overlapping L-shaped hardware at the bolt connection surface, we optimized the plate thickness and achieved high load-bearing capacity. *For more details, please refer to the PDF document or feel free to contact us.
Clear open space! Improved design! Horizontal structural reinforcement hardware that eliminates the need for bracing materials.
The "fire brace hardware" is a reinforcement hardware that can form horizontal structural planes as an alternative to fire braces. The floor amplification (allowable shear strength) of the horizontal structural plane is evaluated based on the size of the compartment. It is mainly used to enhance design and secure natural light by eliminating fire braces in open spaces, and can also be utilized in areas where forming horizontal structural planes is difficult, such as staircases and second-floor bathrooms. 【Features】 ■ Can be used in areas where forming horizontal structural planes is difficult ■ Evaluates the floor amplification (allowable shear strength) of the horizontal structural plane based on the size of the compartment ■ Simple installation by placing the hardware at "2 corners" or "4 corners" depending on the size of the applicable structural compartment and attaching it with dedicated screws ■ It is also possible to use fire braces and structural plywood in conjunction, as specified in the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1347 of 2001 *For more details, please refer to the PDF materials or feel free to contact us.

The second floor is a large space measuring 10.92m × 24.57m! A two-story office building with a span of 11m realized using only residential materials.
Here is an introduction to a case study of an office constructed in Gyoda City, Saitama Prefecture. A two-story building with a span of 11 meters was realized using only residential materials. Although it is relatively large for a wooden office building, the first floor is designed with small rooms to limit the span of the floor beams, allowing for a spacious area on the second floor. This reasonable structural plan made it possible to use residential-sized structural materials throughout. The second floor features a large space measuring 10.92m x 24.57m.

Seismic reinforcement hardware - Kobotto
What is a three-dimensional seismic reinforcement cobot? Until now, the reinforcement of houses has focused primarily on "strength" in specific directions using thick metal fittings. 【Features】 ○ The rounded shape of the cobot disperses and absorbs forces such as vertical shaking, horizontal shaking, and twisting. It is an ideal shape to counteract forces. ○ After repeated experiments, the optimal plate thickness (t=2.0mm) has been determined. The cobot provides solid reinforcement for wooden houses. ○ The brace mounting hole set in the center of the cobot's rear allows for free rotation during connection, eliminating eccentricity. ○ The installation of the cobot body is easy with dedicated stainless coach screws, which also shortens construction time. ● For other functions and details, please download the catalog.
The optimal earthquake countermeasure for wooden houses! This revolutionary seismic reinforcement hardware can disperse and absorb forces such as "vertical shaking," "horizontal shaking," and "twisting."
The "Cobot" is a revolutionary three-dimensional seismic reinforcement hardware that can disperse and absorb forces such as "vertical shaking," "horizontal shaking," and "twisting." Until now, reinforcement for houses has primarily focused on the "strength" in specific directions using thick iron hardware. However, the way forces act during an earthquake is three-dimensional, making "strength" in a specific direction insufficient. The solution to this problem is the "three-dimensional seismic reinforcement hardware/Cobot," which has an ideal shape to counteract forces. 【Features】 - Disperses and absorbs forces such as vertical shaking, horizontal shaking, and twisting. It has an ideal shape to counteract forces. - Set to the optimal plate thickness (t=2.0mm) after repeated experiments and careful consideration. The Cobot firmly reinforces wooden houses. - The brace mounting hole set in the center of the Cobot's rear allows for free rotation during connection, eliminating eccentricity. - The installation of the Cobot body is easy with dedicated stainless coach screws, reducing construction time. - The design of the house is not compromised even when the Cobot is exposed. *For other functions and details, please inquire or download the catalog.
