The so-called “steel and grass” business model has always been the default for CALA towercos, especially for those entities with some roots or links to the U.S., the pre-eminent steel and grass tower market in the world. A simple model based on the premises that towercos only deal with the tower and the ground beneath it, with responsibilities including land acquisition, fencing, outsourcing of the engineering function and maintenance of the actual steel structure. A very different model compared to the complex tower + power that towercos handle across Africa or in certain Asian markets. But the wind has changed and TowerXchange reports for the first time on the diversification efforts finally being undertaken by various towercos across CALA.
