 * Characteristics**

It is light, strong, corrosion-resistant, and easily transported, and particularly lent itself to prefabricated structures and improvisation by semi-skilled workers. The corrugations increase the bending strength of the sheet in the direction parallel to the corrugations, but not across them


 * Uses through history**

Throughout history, corrugated iron was used in sheds, windmills, farms, farm fences, cottages, churches, industrial buildings and so on.
