Creating products that customers can trust.

Since its founding in 1980, Otani Iron Works Co., Ltd. has been working on machinery and metal can processing, developing its own products, and creating products that meet the trust and needs of customers. In particular, its welding technology has been highly praised, and the entire company is working to further improve its processing technology and quality.

We are responsible for the production of all products we handle through our own integrated production process. By reducing unnecessary margins, we can achieve optimal costs and shortest delivery times. By utilizing our engineering capabilities that are suited to the fields of architecture, civil engineering, bridges, and plants, we can respond to customer needs in detail.

We will continue to take on the challenge of being a company that continues to deliver our motto of “making products that customers can trust” by utilizing the technology and experience we have cultivated so far.
