This can be considered the most standard destination. The collected scrap varies and is not limited to just bars and wire scrap. Offcuts and defective products from various processing factories, including sheet materials, strip (thin plate) materials, flat steel, pipes, and metal shavings, are gathered and re-melted. The rule is to identify and collect the steel types as accurately as possible by each type.

We would like to introduce the four-panel manga "Go for it!! Bobin-kun" by Nobu Sakai, <Episode 38>. For example, wire materials used for ropes (twisted wires) are desired to have ± (plus/minus) tolerances or + (plus) tolerances. This is because a certain breaking strength is required for ropes (twisted wires). If each individual wire that makes up the rope (twisted wire) becomes minus tolerance (thinner), the breaking strength of each individual wire decreases. As a result, the breaking strength of the finished rope (twisted wire) becomes lower, falling below the standard values for ropes (twisted wires).

Hard drawn wire is characterized by high tensile strength (breaking strength), low elongation, and elastic (spring-like) properties. It is used in processing and applications that are suitable for these characteristics. In the case of wire materials, the typical applications are "springs" and "twisted wire (ropes)." "Springs" are used as single wires (one piece), while "twisted wire (ropes)" are made by twisting multiple wire materials together.
