Machine straightening (roll straightening, plate leveler, etc.) is often troublesome and applicable under only limited conditions. On the contrary, manual straightening achieves a high level of precision regardless of the material types if operated by experienced engineers. Although there is a few companies specialized in manual straightening in Japan, we are one and only who can straighten any shapes or materials and can satisfy extreme specifications.

Manual straightening has a high degree of freedom; it is very convenient, but the precision substantially reflects the proficiency of the craftsman who operates the machine. Our craftsmen seek straightness and flatness without compromises. To handle high-quality steel products, they must have profound knowledge over metal components, and then press at the proper position with the proper pressure. The training is not easy, but Yamayo has proud craftsmen who are believed to be the best in Japan. We want to offer all our clients the best quality and the best available percentage. With this in mind, everyone at Yamayo works and trains hard for our clients satisfaction.
