Business Growth

Over these 20 years, UIS further expanded our MEP engineering and cleanroom construction to serve major players in Asian semiconductor and Flat Panel Display industry. With the increase demand of cleanroom from Asian High-Tech industries' prosperous development, UIS had experienced significant growth and constructed over 10,000,000 SF within this period of time. To accommodate the high demand for High-Tech facilities plants across Asia, Jiangxi subsidiary of UIS was established in China in 2003 and Singapore subsidiary was established in 2011 to provide more comprehensive MEP and cleanroom construction service locally in China and Singapore.
