Our Steel, Your Future
ーAt a Glanceー

A Manufacturing Company
that Contributes to the
Realization of a Prosperous Society

Since it was founded in 1944, Yamato Kogyo has contributed
to the development of social infrastructure,
as a manufacturing company specializing in steel,
through the production of trackwork parts, cast products,
and steel products.

Steel Production Using
Electric Arc Furnace

For more than half a century, we have been involved in the business of using the heat of an electric arc to melt ferrous scrap that has come to the end of its life so that it can be reborn as new steel products.

Our production method does not only put the circular economy into practice, but also emit far less CO2 than the blast-furnace approach to steel production, and therefore we contribute to the sustainability of the society.

A Steel Business that Supports
Social Infrastructure

Among many steel products, our core offering has been
structural steel which is primarily H-beams used in civil
engineering and construction projects. By these primary
products and other steel products such as stern frames
for large ships and trackwork parts, our business contributes
to support the social infrastructure.

Partnerships with the World’s
Leading Companies

Beginning with the U.S. market in 1987, Yamato Kogyo has expanded its business to eight countries around the world, including Southeast Asia and the Middle East, as well as South Korea.
Having established locations both in markets with robust demand and emerging economies in which infrastructure investment is expected to rise going forward, we contribute to the growth of these countries.

Furthermore, teaming up with leading local partners that are deeply familiar with local business customs and markets, we blend Yamato Kogyo’s production technology with our partners’ local management know-how to grow and develop our joint ventures.

The background to this is our “JV First” concept.
We have achieved sustainable growth by prioritizing investments in facilities, etc. required by the joint ventures, rather than short-term shareholder profits.

Largest producer of steel in the United States. It was through its joint venture with Yamato Kogyo that Nucor first became involved in the production of H-beams. Yamato Kogyo provided the H-beam production know-how and Nucor provided its knowledge of the U.S. steel industry. Since the founding of Nucor-Yamato Steel by the two companies in 1987, the joint venture has captured one of the highest shares in the intensely competitive North American market and has continued to grow steadily.

The Challenge of Becoming One of Leading Companies
in the Steel Industry

Our key words are “steel”, “technology”, “global”, and “the never-ending challenge of manufacturing”.

Going forward we will continue to create new value for steel on the global stage, with the goal of becoming a global leading company that supports world’s infrastructure.

We believe that, as an electric arc furnace steel producer, the expansion of our business is also an initiative that will contribute to the carbon neutrality that has become an issue for the whole world.

Yamato Kogyo Group Vision 2030 is to achieve and solidify the No.1 position as the global leader in structural steel (volume and profitability), and to continue to embrace challenges in new business areas, while designating as key strategies the strengthening of the core structural steel business, and entering new steel, infrastructure and green business areas, in order to realize a sustainable society.
