Tear the tape off at the start of the seam and begin taping again on the opposite side of the metal sheet.
For sheet metal parts the thickness is the same everywhere.
Distance between holes ensures strength of the metal and prevents holes from deforming during the bending or forming processes.
It is recommended that the minimum distance between two extruded holes should be six times the thickness of sheet metal.
