Corporate
Profile

[Company strength]
The origin of our company is the heat insulation work that we initiated when refrigerating warehouses began to spread. We aggressively adopted new technology and new materials regarding heat insulation, and constantly worked towards better product manufacturing. One characteristic of our company is that we can construct and supervise building-type refrigerating warehouses, which is the conventional construction method (warehouses like huge refrigerators to cool and preserve foods). An advantage of our company is that we can construct the whole set of peripheral construction works, as well as insulated doors. We have introduced hot press equipment with a size of 5.5 m × 2.6 m, which is in the largest class in Japan, at our in-house factory. Our productive capacity and performance regarding insulated doors are guaranteed.

[Business description]
Temperature control is very important in distribution warehouses that store fresh foods, because it is necessary to maintain the flavor and freshness of the merchandise. We mainly design and manufacture insulated doors with which merchandise can be stored and retrieved without raising the temperature in the warehouse. We are also developing other businesses. These include construction (heat insulation works, joinery works, and waterproofing works), and design, construction, and maintenance of freezing rooms, refrigerating rooms, cold rooms, fixed-temperature rooms, and constant-temperature rooms. We design, manufacture, construct, and maintain various insulated doors, as well as design, construct, and maintain various kinds of equipment for distribution and cargo handling. We design and construct various kinds of urethane panels, and assemble and process precision sheet metal.

[Strength of products/technologies]
We create a rich local community with our eco-technology. Our goals are to provide a user-friendly use environment, to maintain the value of stored products, and to manufacture environmentally friendly products. We have been pursuing the potential of heat insulation for more than 40 years. Our insulated doors block outside air at the entrance/exit with their excellent insulation properties. They contribute to temperature management in storage, and prevent the degradation of products that are sensitive to temperature variation. A sheet screen is a sheet that raises the heat-retaining properties of refrigerating and freezing rooms. We have a varied product lineup according to the application, including high-speed operating shutter and curtain types. We can make an optimal proposal for you after we hear your request.

[Representative's message]
The predecessor of our company was Toyo Chemical Industrial, which was founded in 1971 as the insulated door unit of Toyo Hoon Kogyo. Our company was renamed as Tohoku Sangyo in 1972, and we started to design and manufacture various electromotive insulated doors. We have been working to expand our business ever since, with a focus on heat insulation works for refrigerating warehouses and freezing warehouses. In 2009 we decided on a corporate policy to advance manufacturing of environmentally friendly products, and took our first new steps by renaming the company to its present name. Our motto is that a door is the entrance to energy saving. We want to be particular about compatibility between convenience and environmental performance, and to provide safe and secure products to customers in Japan and abroad.

[Company structure for market development/overseas expansion]
Our design and construction staff will listen to customer requests in our design office and propose an optimal technical solution for customers in the usual range of our sales activities. Our president directly takes charge of developing new orders based on information received from existing customers. We are doing our best to sincerely satisfy customer needs, whatever they may be, and aiming to cultivate markets by taking on the challenge of applications in various fields.
