Tokyo Sky Tree and SNK

Tokyo Sky Tree whose height is 634m, the tallest tower in the world, was opened on May 22, 2012.
Many people might wonder what relationship exists between Tokyo Sky Tree and SNK when they see the title of this page.
Some people might know that SNK designs and makes machine tools and industrial machineries.
However, in fact, SNK also manufactures cast steel that is called centrifugal cast steel products as the material field.
In this time, this centrifugal cast steel product was adopted as constructional material of Tokyo Sky Tree.

We introduce the other aspect that is different from machine tools and industrial machineries.

What is centrifugal cast steel products
Centrifugal cast steel products

Centrifugal cast steel products are the manufacturing way that steel pipe is made by inserting enough melted pure steel into centrifugally-generated mold.please visit here.
By making the steel pipe with keeping centrifugal force, precise and highly-strong steel pipe can be made.

Why centrifugal cast steel products were adopted to Tokyo Sky Tree

Thin and highly-strong steel pipe was needed in Tokyo Sky Tree because Tokyo Sky Tree has sophisticated design that is equilateral triangle in ground part and close on round shape near the first observation deck. In addition, Tokyo Sky Tree needed to balance building as same as the design with supporting weight of beneath the observation deck.
There, centrifugal cast steel products attracted attention because they met those conditions. Only our centrifugal cast steel products met prerequisite strength, thinness, and length, thus they are adopted to Tokyo Sky Tree.

What’s the other use of centrifugal cast steel products

The centrifugal cast steel products were adopted to Tokyo Sky Tree in this time, but it was adopted to Spiral Tower in Nagoya a few years ago, and in the past, it was adopted to large roof of festive plaza that surrounded the tower of sun in the Osaka World Exposition.
In addition, the centrifugal cast steel products are used as columns of our bridged-type machining center.
They are also used in various purposes. We introduce other usages in detail here, so please feel free to visit.

We would be pleased if you see Tokyo Sky Tree, Spiral Tower, and SNK itself in a different viewpoint.
