Our vision


Our products fill needs because we listen to our customers. Morimatsu Industry is a pioneer in the development of tanks, early on introducing the use of stainless steel. The products we develop are based on today’s needs in society. For the future we are aiming to develop high-quality products that are safe for the environment, by utilizing the recyclable properties of stainless steel.

Our services/products

Morimatsu started using stainless steel as a material for water tanks in 1970. For the structure, we focused on the sphere, a dynamically ideal shape; we were the first in the industry to develop a stainless panel tank made by putting together panel units in any combination, connecting plates to the sphere. Any size tank can be made in this way, from small to very large, and such tanks are used in various fields, from water supply tanks to elevated tanks.

・PRESSURE VESSELS Hot-water Storage Tanks
In 1978, Morimatsu became the first in the industry to succeed in commercializing a hot-water storage tank using SUS444 steel that was fully compliant with Stress Corrosion Crack (SCC) standards. Over 35,000 of these tanks have been sold since that time. The manufacture of SUS444 steel hot-water storage tanks requires no cathodic protection, thereby reducing not only initial costs but making it far more economical in terms of operating costs than other materials that could be used in a hot-water storage tank.

Water is a daily necessity that touches every aspect of our lives. To supply this irreplaceable resource, water supply tanks that store drinking water must offer fully assured safety and stability. In the past, PC, RC, and other types of concrete construction were commonly used for water supply tanks, but these materials had drawbacks in terms of durability and maintenance. Stainless steel then appeared on the scene, offering superior strength, durability, sanitariness, and water tightness. Stainless steel water supply tanks are quickly constructed and are easy to inspect once installed, thereby reducing maintenance costs. A wide choice of types is available from Morimatsu to best suit the physical conditions at the site. Expandability is another feature that allows for flexible responses to needs that change over the long term, and the steel’s ability to be recycled is gaining attention from an environmental perspective.
