Greetings
We, of Denro Corporation, were founded in 1946 by several up-and-coming engineers who should be responsible for the Japan’s future as a presently so-called “Engineering and Solution-Providing Company” aiming at development, design and manufacture of industrial plant equipment. Since then, on the basis of the technology-oriented and human-respecting policies, we have been constantly expanding our business in such fields as “Design and Manufacture of Steel Industrial Processing Plants,” “Design and Manufacture of Steel Towers and Their Accessories,” “Contract Galvanizing and Heat-Treatment,” “Production of Various Special Small Parts Such as Rice-Threshing Machine Blades and Piano Tuning Pins.” We profoundly appreciate your graces that have been helpful to these business expansions in all respects.
Whilst nowadays are said the Era of Innovation, which would imply substantial revolutions and globalization at home and abroad, we will daringly challenge to be involved and assimilated in new tides flexibly, making every effort to be an outstanding Solution-Provider who can give all of our processing Trinitarian “Software,” “Hardware” and “Operation” as well as enhancing the original technology-oriented and human-respecting policies. Denro Corporation is eagerly looking forward to your continuous graces and further encouragement.
Origin of Corporate Name
Mr. Giichi Suzuki, the founder, returned home from abroad after World War II and visited a manufacturer of iron wires and nails, who related to him through his previous profession, and then developed an electrical heating furnace for annealing iron wires in response to the manufacturer’s request.
At that time there were enormous postwar restorative demands in Osaka where many medium and small manufacturers of iron wires and nails commanding almost all domestic market share had a big appetite for new annealing equipment. He, therefore, founded Nippon DenroMfg. Co., Ltd. where Denro denotes electrical heating furnaces in Japanese. The new company sold the equipment at terrific rates and, according to other demands, it carried on developing and supplying various pertinent apparatuses. The foundation of our corporation was thus established.
