THE SECRET BILLIONAIRE: Sanjay Awasthi, the man behind Uganda’s Tembo Steels According to Sanjay Awasthi- the Chairman and Founder of Tembo Steels Uganda Limited- there are two types of steel manufacturers in Uganda. There is a category of steel wannabes- those who import 90%-95% semi-finished steel disguised as raw materials and only add 10%-5% value and then pass that off as steel manufacturing. Then there are real steel manufacturers, who go all the way- from iron ore to liquid steel, to billets and through various forms of continuous configuration that can be made into all sorts of other steel products.
