Transition of IGETALLOY Trademark
Sumitomo's emblem "#" symbolizes the frame of a Japanese old well. Trademark "#IGETALLOY" after a "Sumitomo's emblem", which is registered in 1938. It was named after a “hanging rack”, which is Sumitomo’s symbol. It was renamed to "IGETALLOY" in October, 1959 and have been used to this date.
