Glossary of Perforated Metal (Take round-hole perforated sheet as an example)
Hole Center is the distance from the center of one hole to the center of the nearest hole in the next adjoining row. Holes center is one of two measures of perforation spacing. The other is open area. Because holes center and open area measure essentially the same property (perforation spacing), you need specify only one or the other, not both.
Perforated sheets contain holes and material. Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent. In other words, open area describes how much of a sheet is occupied by holes. If a perforated sheet has 60 percent open area, then 60 percent of the sheet is holes and 40 percent is material.
Note: Specify either Open Area or Centers, but not both.
