Four Benefits of Mitsui Home's Wooden Warehouse Construction 1. Achieving a "20m Large Space" with Truss Technology The truss technology enables large spans, maximizing the efficiency of forklift movement and storage in a spacious environment. 2. Shortened Construction Period through Pre-Cutting and Factory Assembly Factory processing and assembly improve on-site construction efficiency, significantly shortening the construction period. 3. Substantial Reduction in Ground Improvement Costs Wooden structures are lightweight, greatly reducing the load on the foundation. In many cases, even on weak soil, columnar improvements can suffice, significantly cutting costs and effort for foundation work. 4. Optimization of Overall Construction Costs The ease of procuring wood materials, shortened construction periods, and streamlined foundation design reduce the overall construction unit cost compared to steel structures. If you are considering a project with steel structures and are facing issues related to ground conditions, construction periods, or costs, please feel free to consult with us! The Wood Material Business Division provides total support for wooden structures, from structural planning for facility-type wooden buildings to material procurement and construction. We offer free structural assessments and rough estimates based on planning drawings, so please feel free to reach out.

From residential buildings to large-span facilities and livestock barns, we can accommodate a wide range of applications. Large spans can be achieved even with thin materials without using large cross-section materials. Materials that can be used for nail plate trusses were originally limited to "lumber for framed wall construction," but the scope of application has expanded to include lumber for traditional construction (cedar) as well. This allows for materials to be sourced locally, making production and procurement easier. By utilizing locally sourced timber in trusses, local production and consumption can be promoted in each region.

The "Wood Big Span Method," which uses high-durability and high-strength wooden trusses, allows for the construction of warehouses with large spans and high ceilings even in wooden structures. According to the 2019 Construction Start Statistics Survey Report, when comparing the construction unit prices of various structures, it is evident that wooden warehouses are more than 10% cheaper than steel-framed warehouses. Additionally, while the useful life of depreciable assets is set shorter compared to other structures, it does not necessarily mean that the lifespan of wooden buildings is shorter than that of other structures. The "useful life for depreciation" is merely a guideline; for warehouses, the depreciation period for steel structures (with steel thickness over 4mm) is 31 years, while wooden structures can be depreciated in less than half that time, at 15 years. 【Features】 ■ Can be used as a commercial warehouse ■ Achieves a 4m eave necessary for loading and unloading, and a ceiling height of 7m ■ May be eligible for subsidies *You can view case materials from the "PDF Download."

The "Wood Big Span Method" allows for the realization of large spaces such as warehouses and factories using wooden structures, thanks to high-durability and high-strength wooden trusses. Furthermore, it excels in thermal insulation, contributing to improved air conditioning efficiency, and by using a "wooden exposed finish," it also provides humidity control. 【Features】 ■ Low thermal conductivity prevents heat intrusion in summer and enhances heat retention in winter ■ The structural components are lightweight, resulting in smaller design loads for foundations and lower ground bearing capacity ■ Short depreciation period and low dismantling costs ■ In addition to Canadian S.P.F. lumber, it is also possible to switch to domestic timber *Currently offering a "Construction Case Collection"!

Wooden warehouses are full of charm. The characteristics of wood lie in its excellent livability. The properties of wood make it difficult to warm up in the summer sun and hard to lose indoor heat in the winter, which is particularly noticeable when heating and cooling systems are off. Additionally, if specified, domestic timber can also be used. Since the structural body is lightweight, the design load for the foundation and ground bearing capacity can be minimized. We not only design and manufacture connected trusses and wall panels but also provide structural design for the entire building. Our construction team offers specialized support from construction planning to execution and inspection, focusing on framing work and drywall installation, as well as general construction work. 【Features】 - We adopt highly durable and high-strength wooden trusses, enabling the construction of long spans (large spaces) that were previously thought impossible. - Compared to steel and reinforced concrete structures, wood has excellent insulation properties, allowing for reduced operation periods and lower temperature settings for heating and cooling, thereby lessening the environmental impact. - Using wood in construction helps reduce CO2 emissions in the surrounding environment and contributes to the prevention of global warming. - There are also case studies of its use in commercial warehouses. *For more details, please refer to the PDF materials or feel free to contact us.

"Rodman" is a new original tie-down system that replaces traditional hold-down hardware to prevent the overturning of shear walls, responding to the high-strength requirements of shear walls in mid-rise buildings. In wooden mid-rise buildings, enormous uplift forces can occur on shear walls, which may exceed the capacity of existing hold-down hardware. This system was developed to address such significant uplift forces. 【Features】 - By transmitting the uplift forces of each floor directly to the foundation through tie rods, the hardware for each floor can be miniaturized. - The use of high-strength rods allows for a reduction in rod diameter, thereby decreasing the weight and volume of the hardware. - The system can accommodate up to 10mm of movement in response to building shrinkage. *For more details, please contact us.*

Due to many advantages, there is a growing trend in wooden structures of four stories or more. Generally, reinforced concrete (RC) or steel (S) structures are commonly planned, but the high cost performance of the "two-by-four construction method" is gaining attention. This method simplifies the work process by panelizing the floors, walls, and roofs, achieving a reduction in construction time. It is possible to reduce labor costs associated with expenses. Additionally, we propose methods to achieve planning and cost benefits through original technical support such as the "tie-down system" and "wooden elevators." **Advantages of Mid-rise Wooden Construction (4 Stories or More)** - Cost reduction is possible due to differences in foundation design and ground response capabilities. - Simplifying the work process leads to a reduction in construction time. - It is possible to reduce labor costs associated with expenses. - It is feasible to realize plans typically designed for RC or S structures. - It is easier to secure effective space. *For more details, please refer to the PDF document or feel free to contact us.*
