Overlap deviations and deformations on corrugated roof sheets

Overlap deviations and deformations on corrugated roof sheets

Lap lift is described as plastic deformation of the edge of the overlap roof sheet, predominantly in the corrugated profile. The deformations are typically in one or two distinct locations situated between rows of fasteners where the overlap clearance from the underlap sheet varies to the point of being visually apparent.
