Corrugated Sheets
Modern corrugated sheets can vary in coverwidth from 2ft (8 x 3" corr) to as much as 3ft-4.5". (13.5 x 3" corr) Corrugated Sheets are often described by the number of 3" wide corrugations without counting the last lapping corrugation, which can be one or one and a half corrugations. Thus the popular 10 x 3" corrugation sheet covers 2ft. 6" with one no. extra side lap making 11 corrugations, similarly the 12 x 3" corrugated sheet covers 3ft with 13 corrugations.
Modern plastisol profile manufacturers use the same standard width coil as used for the metre wide coverwidth box profile, this in its corrugated form produces a its maximum a 14 x 3″ corrugated sheet.
