The corrugated iron 12ft is a versatile material often used for roofing and walling, as well as prefabricated buildings, particularly in rural areas. All metals corrode, so the main aim with a corrugated iron roof is to slow down this process. The material features regular curved peaks and troughs, with an area of flat edging, and is available in various corrugation styles, including 'weatherboard' or stepped corrugations and small, wide-spaced ribbed corrugations. The dimensions of this corrugated iron are 12ft in length, 600mm in width, and 0.5mm in thickness.
