Nippon Steel Engineering Co., Ltd. (President: Yukito Ishiwa, Head Office:
Shinagawa-ku, Tokyo), in cooperation with Nippon Steel Corporation (President: Eiji Hashimoto, Head
Office: Chiyoda-ku, Tokyo), received an order to manufacture a NS Panel BridgeTM*1 for the Gerezani Bridge as part of the
Japanese government's Official Development Assistance (ODA) project "The Project for Improvement of
Transport Capacity in Dar es Salaam" for the United Republic of Tanzania. We are pleased to announce
that the onsite construction has been completed by Sumitomo Mitsui Construction Co., Ltd. This is the
first time that NS Panel BridgeTM has been adopted for an international project.
The Gerezani Bridge was constructed as part of the Gerezani Road development project to relieve the
chronic traffic congestion on the main road in Dar es Salaam City, the economic and distribution hub of
Tanzania. Since this bridge crosses the railway, the Tanzanian government evaluated the completed bridge
for its Hot-rolled atmospheric corrosion resisting steels for welded structure (JIS G 3114) manufactured
by Nippon Steel Corporation, which does not require re-painting maintenance, in addition to speedy
construction and low girder height (meets the beam height restriction), which are characteristic of NS
Panel BridgeTM.
NS Panel BridgeTM is a new type of unit-type composite deck slab bridge that consists of a main
girder panel, which integrates the composite slab and main girder, and a middle slab panel. The steel
shells of the main girder and composite slab are integrated at the plant beforehand to make the onsite
construction process simpler and quicker. In addition, since NS Panel BridgeTM does not require
onsite under-girder work, such as the installation and removal of suspended scaffolding and floor slab
formwork, it can be erected with minimal traffic restrictions, especially for bridges that cross roads or
railways, thereby reducing traffic congestion and other burdens on the surrounding area.
Going forward, Nippon Steel Engineering Co., Ltd and Nippon Steel Corporation will continue to work
together to actively deploy NS Panel BridgeTM for road (bridge) development projects, mainly in
Asia and Africa, and help export high-quality infrastructure*2 that drives development of
developing countries by utilizing advanced Japanese technologies, a priority initiative of the Japanese
government.
*1 Our new unit-type bridge that achieves lightweight, low girder height and speedy construction.
*2 Infrastructure that is resilient against natural disasters, inclusive of every single individual and
sustainable in terms of impact on society and the environment.
