Yin Enterprise was established in 1989. Initially, the business was primarily importing and exporting steel associated hardware. In recent years, we concentrate on manufacturing fireproof building materials such as Fiber Cement Board, Calcium Silicate Board, and Coating Ceiling Board. I-Yin is also expanding its business territory by acting as the agent for international import and export trade.

Our products have been widely used in business and administration office buildings, exhibition halls, hospitals, train stations, MRT stations, movie theaters and many other places. Our actual achievements included TSMC, Tainan prosecutors' office and CHI MEI Optoelectronics and Kaohsiung MRT stations. We also supply fireproof ceilings for Nan Ya Plastic Corporation, all 7-11 stores as well as the Family Mart convenience stores in Taiwan. Ever since I-Yin combined with EVERITE series products and technique experience, we have developed Nutec Board to be used in half wet indoor partition board, dry and wet indoor partition board.
