Peterson Company carries expanded metal in a variety of materials such as aluminum, stainless steel, galvanized, carbon steel, copper, brass and titanium.
Flat – Expanded metal that is cold-rolled after expansion, to provide a smooth, flat and level sheet. The flattening process will reduce the original thickness by
approximately 10%.
Regular – Standard expanded metal with raised diamonds.
Strand Width – Width of 1 strand.
Strand Thickness – Gauge thickness of strand.
Bond Edge – Part produced with closed diamonds.
Random Sheared Edge – The shearing operation produces an “open” or random edge.
Auxiliary Operations – In-line slitting can be provided holding tolerances as + -.005
inch. Circle shearing, edge flattening and bending are also available.
Squareness – An expanded metal blank will be square to within the largest tolerance of length or width. (Example) Part size 24” (+-1/32) LWD x 24” (+-1/16) SWD will be square t within 1/16”.

HOW TO SPECIFY / ORDER
EXPANDED METAL CATWALK GRATING
When considering lightweight, economical catwalk alternatives, consider reverse flow Expanded Metal Catwalk Grating. Manufactured with the LWD spanning the width (short dimension) of the sheet,
Catwalk Grating is commonly stocked in 2’-0, 2’-6, and 4’-0 wide sheets. These products can often be installed on walkways without waste or additional shearing charges.
