1. Value-added Product Proposals
We are able to propose products with the perspective of a manufacturer (e.g. energy burden reduction and cost reduction efforts).
2. Stable Supply
We are able to control quality in-house because we are also a consumer of sales products. We store some products in-house as inventory.
3. Pursuit of Low Prices
We are able to offer competitive pricing because we have multiple purchase sources. (Purchase source examples: Brazil and Russia, etc.)
The history of TOYO DENKA KOGYO is intertwined with the iron and steel (including ferro-alloys) materials industry in the main.
We have unceasingly studied technologies based on the experience we have cultivated since our foundation as a company on the front line to win the great trust of all our users today.
We have become able to respond to even more detailed needs by having networks overseas in addition to Japan in our business fields.
Ferro-silicon is essential in steel manufacturing as a deoxidization agent.
We have stably imported ferro-silicon by signing a business partnership with a Brazilian manufacturer since 1984 by taking advantage of our expertise in manufacturing ferro-silicon over many years.
We installed sizing facilities from Japan in our business partner in Tianjin in China in 1997 and now import goods upon carrying out thorough quality control with ferro-silicon crushing, sieving and analytical facilities.
We will continue to provide high-quality products with confidence in the future.
