桑名金属工業 Company Profile

We are a young company, but while valuing tradition, we will continue to provide new value to the industry in line with customer needs and market changes.

Our company is a young organization established on August 1, 2024, as a separate entity from Protearial Co., Ltd.'s piping equipment business. However, its roots can be traced back to Tobata Casting Co., Ltd., which was founded in 1910. When we launched our first product that same year, we cast it with the wish for "greater strength, smoother surfaces, and more beautiful curves," giving rise to the "Hyotan" mark. For over 100 years, we have continued to produce cast products under the testament of tradition and trust. Today, we manufacture and sell not only fittings and valves but also sealed diaphragm expansion tanks, semiconductor flow control devices, and cold water supply equipment. Furthermore, we take pride in our comprehensive capabilities, which improve on-site conditions through our technical expertise, support systems, and quality control measures, enabling us to meet societal needs such as efficient energy use and the realization of a safe and secure society. Although we are a young company, we cherish tradition while continuously providing new value to the industry in line with customer needs and market changes. We are committed to making efforts to meet our customers' expectations in the future, and we sincerely hope for your continued support.
