Business Details
The segment integrates the manufacture and sale of fireproof covering materials, interior building materials, and multifunctional materials based on xonotlite-type calcium silicate materials, together with the contracted execution of construction work such as steel-frame fireproof covering construction and asbestos removal construction. Major customers are construction and contracting businesses serving logistics facilities, offices, government agencies, and residential housing. By providing products and construction services in an integrated manner, the segment achieves quality control and smooth incorporation of customer feedback. Centered on products certified under the Building Standards Act, the segment positions its contribution to disaster-resilient urban development as a key social significance of its business.

Key Products
Growth Drivers
- Increased orders for large-scale fireproof covering construction projects for logistics facilities, offices, government agencies, and other clients
- Increased sales volume of fireproof covering materials for residential applications and orders for chimney lining materials for large-scale projects
- Promotion of functional improvement of fireproof building materials, new product development, and new application development under the medium-term management plan
- Uncovering latent demand through construction methods tailored to customer needs and expansion of certifications
- Continued social demand for fireproof covering materials driven by demand for disaster-resilient urban development
- Expansion of sales of peripheral-domain products such as interior finishing materials and molding materials for CFRP
Risks
- Risk of delays in progress of large-scale non-residential projects (a risk that materialized in the prior period)
- Pressure on gross profit due to rising external construction costs and delays in passing on price increases
- Difficulty securing construction personnel and partner companies due to the declining birthrate, aging population, and overtime work cap regulations in the construction industry
- Trends in the housing market (impact on personal consumption from rising interest rates and prices)
- Increase in postponement or cancellation of investment plans by customer companies against the backdrop of soaring material prices
- Legal risk related to construction asbestos damages lawsuits
