NEENAH GRATE INFORMATION

The following table lists the Neenah catalog designs furnished with grates. In addition to the free opening areas which are necessary to determine the discharge, the tables also show the grate type or style which are shown below for easy identification.




Special notes on Neenah grate types:

  • Type K indicates "Special" grate designs and is not among standard types as illustrated.
  • Inlet grate type A or C can vary depending on how it is installed. If grate is installed with long side of openings perpendicular to flow, it is a type A grate, and if grate is installed with long side of openings parallel to flow, it is a type C grate.
  • Inlet grate type B or D can vary depending on how it is installed. If grate is installed with long slots perpendicular to flow, it is a type B grate, and if grate installed with long slots parallel to flow, it is a type D grate.
