The “margin” on a perforated sheet or plate refers to the distance from the edge of the
sheet to the first perforation along the same dimension. “No margin” refers to the last row
or set of perforations extending off the sheet or plate.

On staggered pattern perforations, the end patterns will either be “finished” or “unfinished” depending on the tooling available. An unfurnished end pattern is Standard; however, a finished end is available as a non-standard item.

“Unfinished” end patterns are standard on some staggered pattern perforations, meaning the hole pattern appears incomplete at the end of the sheet.
