  Panel bridge(2)

  The "Panel Bridge" is a new type of assembled bridge that consists of main girder panels and intermediate deck panels, integrating the composite deck and main girder to achieve rapid and easy construction. It can accommodate continuous girders and arch bridges. It can also handle construction where the replacement of an existing bridge requires the removal of the old bridge and the installation of the new bridge to be divided.

  Seismic isolation device(3)

  Protecting precious lives, buildings, and assets from major earthquakes. Seismic isolation, earthquake-resistant, and vibration control devices for construction! ■ Seismic Isolation Component for Construction 'Spherical Sliding Bearing NS-SSB' A seismic isolation device made of iron that utilizes the principle of a pendulum, the 'Spherical Sliding Bearing NS-SSB.' Due to its iron material, there is no variation in quality, and it is exceptionally strong. Moreover, the natural period of the isolation layer is not affected by the weight of the building, providing sufficient seismic isolation effects for both heavy and light structures! ■ Earthquake-Resistant and Vibration Control Component for Construction 'Unbonded Brace' An excellent buckling-restrained brace, the 'Unbonded Brace,' which can be applied to both new constructions and seismic retrofitting. It has been a bestseller for 30 years since its launch, surpassing cumulative sales of 100,000 units.

  Cover plate(1)

  We introduce bridge products utilizing advanced technology from Nippon Steel & Sumitomo Metal Engineering, including the "Kakubuta Bridge," a square steel pipe slab bridge that can be constructed quickly and easily even in narrow spaces, as well as "Panel Bridges," "H-BB," and "CT-BB."

  Grating floor slab(2)

  The "Grating (Solid Type)" is a bridge product that allows for a thinner deck slab due to the use of high-strength I-beams in its lattice deck design. Additionally, since it is manufactured in a factory, it significantly reduces the need for on-site construction management, enabling a construction period that is shortened to about 1/2 to 1/3 compared to RC deck slabs. The grating deck slab can adequately handle increasing traffic volumes and large vehicles with its thin slab thickness, and concrete can be poured simply by placing it on the girders, allowing for rapid construction. A design system using computer programs is also fully equipped.

  Kakuta Bridge(1)

  The "Kakutahashi Pon! Metal Kit" is a new type of metal deck bridge that involves installing square steel pipes one by one, inserting horizontal steel pipes on-site, and pouring concrete to create panels. It allows for rapid and simple construction by transporting factory-made panel units to the site and integrating them together. Compared to PC bridges, it can reduce the design reaction force of the substructure by about 20%, allowing for a smaller substructure. Additionally, due to its low girder height structure, it is possible to reuse existing substructures during bridge renewal. It is suitable for bridges over urban rivers with girder height restrictions and for bridges that intersect with main roads and railways.

  H-shaped bridge(0)

  As of March 2023, the manufacturing and sales of HBB and HBB-C will be discontinued. "H-BB" is a modular bridge made of H-shaped steel, and "CT-BB" is a modular bridge made of CT-shaped steel, both having a long history and a wealth of achievements, with numerous installations across the country since their release. The structures include non-composite girders (H-BB, CT-BB) and composite girders (H-BB-C, CT-BB-C), and they come in various types such as road bridges (A and B live loads), forest road bridges, agricultural road bridges, and side road bridges, covering spans of approximately 35 meters. We also offer a weather-resistant steel specification that eliminates the need for painting and allows for maintenance-free operation.
