These grids are available in molybdenum, titanium, aluminum and stainless steel 316. The grids are made by a high precision etching process. The thickness is approximately 25µm for Mo and Al, 15µm for Ti and 12µm for stainless steel. The pattern with the 350-400µm wide rim on the PELCO® grids provide greater stiffness and improves handling of the grids. All grids have a standard diameter of 3.0 to 3.05mm. Available styles are: square mesh, hexagonal mesh, double folding grids, tabbed grids, slotted and aperture grids. The square mesh and double folding grids have a center mark. For standard grid materials such as Cu, Ni and Au, please go to the PELCO® Grids page. Packaging: Mo, Ti, Al and Stainless Steel grids are packaged in 25grids/vial.

Rim Width:	350-400µm.
Thickness:	25µm for Mo, and Al 15µm for Ti 12µm for Stainless Steel
Diameter:	3.0 to 3.05mm
Finish:	Being made of thin foils, both sides show same surface
Packaging:	25 grids/vial
Pitch:	Is 1"/mesh or 25.4mm/mesh Example 200 mesh pitch = 25.4/200 = 127µm

From the drawing above, the hole and bar widths are shown. Sometimes "pitch" is used in this terminology and it is the equivalent of hole width plus bar width
