Greatness Sanitary Industrial, Co. (GSI) was established in 1978, originally conducting business as a family-owned casting factory. Success in this field led to increased demand from our customers and the subsequent need to expand the factory to 4,000 square feet as well as service offerings to include manufacturing, assembly and packaging of residential style faucet and hardware. aa-514-b 928010 921040 921010 Company Proflie  ∣  Service  ∣  Products  ∣  Contact us   No.198, Maming Rd., Xiushui Township, Changhua County 504, Taiwan (R.O.C.) © 2010 Greatness Sanitary Industrial Co., Ltd All Rights Reserved TEL：886-4-7680872　　FAX：886-4-7680873 Design By Eztrust.
