Sankou Steel Co., Ltd.

Steel plate melt-cutting and plate working for applications related to the environment, new energy, aircraft, and many other fields.

Our main business includes the design and manufacturing of various pressure vessels, welded products, and plate working products, commissioned development of industrial machines, and melt-cutting of steel plate members for industrial and constructing machines. We can seamlessly perform the entire process from material cutting through to final product processing within the same factory. We have delivered steam kettles for waste plastic disposing facilities, semiconductor factories, and food manufacturers; various vessels for water treatment plants; and a variety of parts of power-generating facilities, building facilities, oil storage facilities of fishing ports, tanker truck parts, and so on. We supply large, durable products related to the environment, new energy, and aircraft, including dehydrogenation units, hydrogen addition devices, and biodiesel plant equipment.


Other presentation

[Company strength]
Since our melt-cutting and plate working sections are located in the same factory, we can seamlessly perform the entire process from material cutting through to final product processing. The spacious factory has two 10-ton cranes and a 7.5-ton crane, in addition to sites for temporary assembly and storage so that we can fabricate large structures weighing around 20 tons. We collect detailed information from customers and all of our departments and personnel work in an organized manner to immediately fulfill requests.

[Business description]
Our company’s main business is the design, processing, manufacturing, and selling of steel plates and plate working products. Our steel plate business mainly covers iron frame members, bridge members, built H-beams for construction; parts and components of various industrial machines; and precision cutting/melt-cutting. In recent years, we have introduced plasma and laser cutters to cut stainless steel and titanium plates in addition to conventional steel plate cutting. Our plate working section has a factory certified to manufacture Class-1 pressure vessels where we primarily fabricate various pressure vessels, steam kettles for food processing, vacuum containers, and various oil tanks. Our factory is also certified as an inspection factory by the Japan Water Works Association and carries out machining and welding for a wide range of industries.

Metal products manufacturing

[Strength of products/technologies]
The steel plate section has many cutting devices such as gas, laser, and plasma cutters in addition to NC cutters. The plate working section has introduced YAG laser and other advanced welding technologies. The work site is certified to fabricate Class-1 pressure vessels and is also approved by the Japan Water Works Association as an inspection factory. The facility has produced more than 1,000 Class-1 pressure vessels. We prepare data sheets, design and manufacture pressure vessels for plant facilities, and carry out various analyses using 3D analysis software.

[Representative's message]
One of our missions is “To be a popular and indispensable company in society.” We always consider whether our customers are satisfied with our products and services, whether we are trusted by customers, and whether we pursue profits for both our customers and ourselves. We are a group of employees who can answer these questions independently in day-to-day operations.
