Vision of Daiwa Steel Tube and one to ONE
Here we have a 6-meter-long, 48mm diameter tube that just came off the line.
This simple form of tube will eventually take on many forms, supporting industries and people’s lives.
We wish that people all over the world can enjoy a safe, secure and healthy life, and create a successful future through the manufacture of tubes.
Therefore, we always emphasize on “one to ONE.”
From the manufacturers’ perspective (one) to the users’ perspective (ONE). From creating products (one) to creating value for users (ONE).
The small awareness of each of us involved in product manufacturing can lead to a great deal of value for society to connect with “one to ONE.”
