Two different designs were offered for the boiler structure of Matimba Power Station, one being based on concrete pylons with a dimension of 7,5 m x 7,5 m each, the other using steel pylons measuring 2,5 m x 2,5 m. A detailed comparison revealed definite advantages on the part of the steel alternative: lower cost, a reduced construction period and a significant increase In usable floor space between the columns. This article gives details of the steel structure design principles and also refers to manufacture and erection procedures that had to be adapted.
