The steel parapet fascia, a replacement for the concrete?

In home building, the cornice or concrete fascia is a a well known addition to Nigerian architecture of recent years. In the last 7 years, a lot of new houses has been finished with various designs of parapet cornice of varying shapes and sizes, but there has been a lot of concern from new home owners, especially THE COST. Building a concrete parapet is expensive, its heavy and it takes time. This is why some researchers came up with ideas on how to solve this three problems. Their solution was to make the parapet with a prefabricated material which could be readily available and more affordable than concrete fascia. I will show samples of the new parapet made of steel, there are some others made with aluminium.
