The Corrugated Iron 6ft was most frequently used for roofing and walling, and also for prefabricated buildings, especially in rural areas. All metals corrode, so the main aim with a corrugated iron roof is to slow down how quickly this happens. The regular curved peaks and troughs, curved corrugations with an area of flat edging, and 'weatherboard' or stepped corrugations are all features of this product. It's available in a 6ft size.
