Corrugated iron
Sheet-iron or steel coated with zinc (galvanised), and rolled into a continuous wave form. This stiffens the sheet in one dimension. Corrugated iron was formerly extensively used for the walls and roofs of temporary buildings (see tabernacles). Sheets curved in the direction of the corrugations are remarkably strong, and were used in building Nissen huts, as in the Italian Chapel in Orkney. Sheet steel with sharp-edged corrugations is termed 'profiled' steel.
