In such period, our founder, Toshikazu Ichino, was among the first to notice at the marketability of the pickled steel sheet as a commercial product. He started stocking the pickled steel sheet with the second grade products such as overrolled steel which come from the steel maker's factory. At the beginning, the sales activity of the pickled steel sheet was difficult because of low market recognition, but he explained the merit of its workability to pressing plants and sheet metal plants carefully, then the commercial scene was expanded little by little.

In 1965, a lot of second grade pickling products at the experimental stage was generated from the Hukuyama Iron Mill of NKK Corporation(about 2,000t). Our company purchased all of them and sold out successfully.

This led our company to make the pickled steel sheets as flagship products. In late 1960s, our company became a dealership dedicated to the pickled steel sheets, dealing with most of pickled steel sheets manufactured by NKK.

Before long, the usage of the pickled steel sheet widespread to the car components, the electrical machineries and the constructions. Since our company made the market recognized the pickled steel sheet as a commercial product and expanded its channel for sales widely, we were then recognized as "Pickeld steel company Irifune" or "a pioneer of pickled steel sheet sales" by the industry.
