We have devoted ourselves to the research development of precise cold drawing steel tube since our foundation,and thus have produced the huge-caliber hydraulic cylinder tube used to the construction facilities, OST used for the hydraulic piping and heat-Exchanger & Boiler Tube used to all kinds of plant by the newly-established 'Dadae Factory' including the precise cold drawing steel tube used to the suspension device, direction device and brake of car.

We contribute every energy and efforts so as that we can cope with the rapidly-changed industrial environment and the demand of consumer who requests the better things, and promise to jump toward "Best Enterprise in the World" reputable in the scope of Precise Drawing lndustry through the continuous technical development and facilities investment with the challenging spirit which we are not satisfied with the current situations.
