PFI Project

This PFI (private finance initiative) project was undertaken to improve the Central Government Office Building No. 7, which houses the Ministry of Education, Culture, Sports, Science and Technology and the Board of Audit of Japan. The BTO (build-transfer-operate) scheme is used for the design, construction, maintenance, and operation of the building for a 15-year period, as well as associated private facilities. The total floor area of the building is 230,000 m².

STAN Package R

STAN Package R harnesses the combined strength of our pre-engineered products and steel structure engineering technologies to cut construction time and cost while boosting quality, for optimal performance in every building production process. NIPPON STEEL ENGINEERING CO., LTD. has built up a solid track record that includes over 10,000 factories, warehouses and office buildings.

High-Tech Steel Structures

Spatial Structure Engineering

“Special steel structure technology” is used to construct beautiful and dynamic large spaces, such as soccer stadiums and other types of athletic event spaces. NIPPON STEEL ENGINEERING CO., LTD. carries out everything from structural design to fabrication and construction work, utilizing the NIPPON STEEL GROUP's unique technologies for making and using steel.

Tension Structures

The tension structure realizes a lightweight, long-span roof frame, and a glazing system allows for a transparent facade. Tension members that meet various design requirements from large to small capacity, along with unified design joints, are available.

System Trusses

The wide space created through the use of steel pipe space trusses has brought into existence a variety of architectural expressions in sports / cultural facilities, etc. NIPPON STEEL ENGINEERING CO., LTD.'s system trusses, which include the simple and low-cost W truss, in addition to the NS truss—which has produced many achievements due to its excellent structural form—are designed in the pursuit of various possibilities.

Tower Engineering

NIPPON STEEL ENGINEERING CO., LTD.'s excellent structural design and construction technology achieves high-rise buildings that are full of functional beauty. Our spirit of innovation—which can be seen in our many achievements in Japan and overseas—is highly rated.

Hybrid Structures

Large spaces are realized using wooden hybrid trusses, which consist of wooden members and steel plates / tension rods. Hybrid structures are attracting attention as a new technology that can impart warmth and serenity to large-scale structures.

Response Control and Seismic Isolation Devices

UBB™ (Unbonded Brace)

UBB™ is a structural brace element consisting of a steel core plate which is restrained by mortar and steel tube. A membrane called the unbonding material, located between the mortar and the core plate, ensures that axial forces in the core plate do not transfer to the mortar and the steel tube. This ingenious combination of components produces stable and symmetric tension-compression hysteretic behavior.

NS-U™ (U-shaped Steel Damper)

The base isolation U-shaped damper is a new steel damper fabricated from high-quality rolled steel (SN940B). Some of its excellent characteristics include high quality, high level of design freedom, nonorientation, low cost, and ease of inspection.

Bridge Products

Kakuta Bridge™

Kakuta Bridge™, with maximum span length of 16 meters, is a steel deck slab bridge using steel square tubes and steel pipes. The main purposes of development of this bridge are to cut the cost of construction and to shorten the construction period. As the square tubing used for the bridge is very stiff and light in weight, it permits reduction of the girder height and dead load compared to ordinary steel bridges. The bridge installation work can be carried out even in confined working spaces.

Panel Bridge™

Panel Bridge™ is composed of a steel-concrete composite deck, steel I-beam, and SRC cross beam. The characteristics of the bridge–aside from having a maximum span length of 40 meters–are as follows. (1) It can be applied to short span bridges (2) It has small girder height (3) It has a lightweight dead load (4) It has a rapid construction period.
