Perforated Metal 7 PERFORATED METAL | Perforated Patterns End Patterns 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. Consult Ametco for details. “Unfinished” end patterns are standard on some staggered pattern perforations, meaning the hole pattern appears incomplete at the end of the sheet. “Finished” end patterns are non-standard on most staggered pattern perforations, meaning the hole pattern is complete at the end of the sheet. Standard Unfinished end pattern Margins 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. Minimum Margins Perforated stock size sheet or plate with minimum margins. Specified Margins Sheet or plate re-sheared after perforating with margins specified.
