Kayson is a privately held engineering and construction company providing world-class design, management, procurement and construction services to develop, engineer & build projects for customers both in Iran and overseas.
We have devoted a sizable portion of our resources to strategically penetrate attractive markets around the globe: Equatorial Guinea, Algeria and Sudan in Africa; Kyrgyzstan and Kazakhstan and Belarus in the Common Wealth of Independent States; and the Bolivarian Republic of Venezuela. We have been chosen as Iran’s exemplary exporter of technical & engineering services for six years (2000, 2001, 2007,2008, 2009 and 2010). We are designing and building some of the world’s largest projects. As a result, today, a large percentage of our output is generated abroad. Kayson is thus one of Iran’s most international engineering & construction services providers. The services that we offer our national and international clients encompass nearly all segments of the construction market. Kayson provides world-class services for the complete life-cycle of projects and continually enhances values for clients, partners, society and its shareholders.
