Piano wire

We succeeded in the first domestic production of piano wire in Japan for high-end springs.
It meets various needs, such as music wire (piano string), from which the name piano wire originates, as well as straightened or high-strength piano wire for special purposes.
The advanced wire making technology developed through our experience in piano wire is applied to the hard drawn steel wire used for various applications such as bed and shutter springs, household appliances, and automobile seat springs.
In order to meet the needs of a wide variety of customers, we also offer plated wire with excellent workability, corrosion resistance, solderability, and conductivity.
