Nippon Steel Corporation is the third largest steel producer in the world. They invest heavily in R & D and have developed a number of speciality steels for specific needs.

As Japan is very similar geographically and seismically to New Zealand, Nippon Steel speciality steels often have direct applicability here.

Nippon Steel has developed two types of corrosion-resistant, weathering steels which can be used in New Zealand in C4-C5 corrosion zones; NAW-TEN (Nickel added) and CORSPACE (Tin added).

SBHS (Steel for Bridge High Performance Structures) are high-performance, high-tensile strength steels developed to reduce the construction costs of steel bridges.
