Reason for selection: In a project to upgrade infrastructures of Tokyo to deal with localized
torrential rain allegedly caused by the climate change in recent years,
stainless steel (SUS304) was selected for the metal support of the ventilation
duct. With this adoption, it is anticipated that stainless steel will make
greater social contribution in infrastructure improvement works.Tokyofs decision to use stainless steel for such application is likely
to help prompt other local governments to follow the suit and lead to increased
use of stainless steel thanks to its advantages in corrosion resistance
and life cycle cost.
