Currently, about 55% of the artificial forests in Nagano Prefecture are larch forests, and in the Higashi-Shin area where our company is located, larch accounts for more than half. Our company accepts local larch logs, processes them into lumber, and manufactures and processes laminated wood. In this article, we will introduce the "Lumber Factory" that handles everything from log sawing to the gluing process for laminated wood. You can view the detailed content of the article through the related links. For more information, please feel free to contact us. [Published Content (Excerpt)] ■ Lumber Factory ■ JAS Certified Factory ■ Process Introduction ■ (1) Log sawing with automatic sawmill ■ (2) Medium-temperature steam drying of laminates using a biomass boiler *For more details, please refer to the PDF materials or feel free to contact us.

Larch is a tree species native to Japan and is the only deciduous conifer among Japan's coniferous trees. In autumn, its leaves turn golden, beautifully coloring the mountainous landscapes of Nagano Prefecture. Shinshu larch has beautiful grain, and in addition to the inherent beauty of the wood itself, when manufacturing laminated wood, the emphasis on visual appeal makes a difference in its beauty when used for exposed surfaces. Although it has been utilized for a long time, larch is a very unique species compared to others. Processing requires effort and skill, but by carefully drying and utilizing larch materials, it becomes a dense, strong, and stable wood. **Characteristics of Shinshu Larch** - Beautiful grain - Higher strength compared to larch from other prefectures - High resin content, providing anti-decay and anti-insect effects For more detailed information about larch, please refer to the link below.

The "Truss Frame Construction Method" is a wooden portal frame that fully utilizes the performance of wood. By using trusses, the cross-section of the components that make up the frame is reduced, eliminating the need for bracing or shear walls in the portal frame, thus lowering assembly costs. Due to the small and short components, assembly can be done without heavy machinery (cranes). Additionally, the space required for placement is minimal, and no special temporary structures are needed. 【Features】 ■ Small and short components ■ Easy assembly ■ Amazingly low price *For more details, please refer to the catalog.
