The basic perforation patterns most commonly used can be defined by determining the following criteria:

1. Hole shape - Hole size - Orientation of hole relative to edge of plate

2. Hole pattern - Distance between hole centres (pitch)

3. Orientation of pattern relative to edge of plate

4. Plain (unperforated) margins between holes and edges of sheet

Terminology

Length (of sheet/plate) = will always be taken to be the longer of the two dimensions

Width or height (of sheet/plate) = the shorter of the two dimensions

Pitch = measurement from centreline of one hole to centreline of next hole

Bridge = measurement from edge of one hole to edge of adjacent hole - ie the amount of solid material between holes
