What it is and how it is specified
Corrugated sheet is flat coil roll-formed into a profile. In Pakistan the two common profiles are the American profile and Gol Nali, and sheets are ordered by profile, thickness and length rather than by weight.
Two things decide how long a corrugated roof lasts, and neither is the profile. The first is the zinc or aluminium-zinc coating mass on the substrate; the second is whether the sheet is painted and with what system. Our zinc coating guide and paint systems comparison cover both, and the gauge chart converts the gauge numbers the market quotes into millimetres.
Duty and origin
Duty exposure follows the substrate and its origin, not the corrugation. Chinese galvanized and colour coated coil both carry anti-dumping duty; locally produced coil does not.
