Description
Galvanised Steel Blank Plate
Description
Our steel blank plates are hot-dip galvanised after fabrication so should not rust. The plates are manufactured to suit PN10/16 pattern and are suitable for use with either stub flange assemblies (stub flange and backing ring) or full face flanges.
Pressure Rating
Galvanised steel blank plates have a minimum pressure rating of 20 bar (290 psi).
Plate Sizing
The number and diameter of holes together with the PCD determines the blank plate size and pattern. The PCD (Pitch Circle Diameter) is the measurement from the centre of one bolt hole, across the centre of the blank plate, to the centre of the opposite hole.
The table below details the specification for both imperial and metric PN10/16.
