大丸工業 Company Profile

We will uphold a customer-first philosophy and aim to be a first-call company.

Since our establishment in 1973, we have been engaged in the manufacturing of bronze alloy sand castings, primarily focusing on various types of valves for over 50 years. In 2004, we established a subsidiary, Daimaru Industry, in Dalian, China, and have developed a consistent production and mass production system centered on water faucet hardware and general valves, selling both domestically and internationally. We respond to a variety of customer needs, from large to small items, as well as small lot products and items made from different materials. Please feel free to contact us with your requests.
