Founded under the name of Gwangyong Precision, by way of the name change to Seil Industrial Instruments, we have built up various experiences of casting, processing, and producing faucets(KS-certified), water gauge cover and parts. With those proud experiences. Upon the corporate registration, Daehan Industry finally set off in December 2005 to produce and sell water gauge. We hereby promise, with the company philosophy of “Quality Management, Quality First”, to do our utmost for customer trust and company development to stand on top of the field.
