The construction supply business consists of four segments: Construction Materials, Housing Materials, Insulation Materials, Renewable Energy Materials.
Amid the tightening of regulations on the construction industry with the revised Building Standards Act established in 2006 and a contraction in construction services across the board among construction supply trading companies affiliated with major trading companies handling construction supplies, the Company has prepared a construction management system and strengthened its construction functions as a construction supply trading company. Since then, we have strengthened our functions such as processing, distribution, and system provision, and enhanced functions that assist customers as a “value-adding trading company.”
For high-performance non-residential construction materials (wall materials, fire-resistant coverings, etc.) used primarily in large logistics facilities and plants, as well as pile-related and civil engineering materials (piles, foundation improvement methods, EDO-EPS methods, and transparent plastic underground retaining blocks, etc.), we are involved in everything from design considerations to construction, and provide goods and services to customers via a nationwide sales and construction network.

Thermal insulation panels for housing・Example of Construction

We will contribute to the energy savings by providing insulation panels used to create refrigerated spaces in non-residential facilities, such as food factories and distribution warehouses, as well as offering a wide range of high-performance insulation materials and techniques for residential buildings. In residential, by offering a full-precut service to housebuilders and taking responsibility for layout, processing, and distribution functions, we help to save labor associated with measuring, cutting, and disposal work at construction sites.
