Award winner |
|
| NS Cover Plate |
 |
|
 |
| Applicant: NIPPON STEEL & SUMIKIN ENGINEERING CO., LTD. |
|
Reason for selection:
NS Cover Plate, with highly durable and painted stainless steel used for
the exterior, serves both as permanent cover and scaffolding for such structures
as elevated bridges.
The Cover Plates protect highway and railway bridges as well as those built
over the sea from such deteriorating factors as wind and rain, sunlight
and salt, contributing to extending the lives of these structures. In addition,
the Cover Plates work as permanent scaffoldings to enable visual inspections
from close distance and ensure safety.
Stainless steel used as the material is expected to last 100 years and
will greatly contribute to extending the lives of infrastructures, which
is a social need, and to facilitating maintenance.
The adoption of SUS430J1L, a ferritic grade, has enabled the parties concerned
(1) to attain sufficient corrosion resistance, (2) to attain linear expansion
ratio similar to that of carbon steel and (3) to enjoy stable costs. Furthermore,
fluorine resin painting is deemed to further enhance the durability of
the Covers and to harmonize them with surrounding landscapes where necessary.
