Haneda Airport D-runway Stainless Lining Jacket

Nippon Steel Engineering Co., Ltd and Joint Ventures

Re-expansion Project is a very important national infrastructure in Japan, and durability of 100 years and maintenance sustainability is needed.

Concerning the method to avoid corrosion for steel constructions, especially materials of the pier, there were some considerations: coated steel may have a re-coating cost problem and titanium clad may also have an initial excessive cost problem. Finally the film lining construction method with seawater-proof stainless steel were considered to be much more superior for the corrosion resistance and LCC (Life Cycle Cost) evaluation, and the first large-scale application to the airport facilities was realized.

The pier construction was accomplished by the collaboration between NSSC 270 stainless steel, which permitted use with film due to its excellent seawater corrosion resistance and the efficient indirect seam welding process. Due to this collaboration effort, we were able to achieve requisite standards unparalleled by our competition.

As for this technology, expansion to many steel structures in coastal and offshore areas will be considerably expected in the future.
