Eco-friendly and Sustainable

強く・安全

By further improving the environmental performance of steel structures, we aim to reduce the environmental impact of buildings and infrastructure and contribute to a sustainable society.

Environmentally-friendly steel construction

Steel structures are environmentally-friendly structures that can help minimize the cross-section of structural members by utilizing the strength of steel materials, thereby reducing CO₂ emissions by conserving resources.
In addition, almost all of the steel materials are repeatedly reused while maintaining their quality and performance. The concept of environmental impact that takes into account the effect of recycling has been standardized^* in Japan and overseas.

Standardization^*:

ISO 20915 "Life cycle inventory calculation methodology for steel products"
JIS Q 20915 "Life cycle inventory calculation methodology for steel products"
