Best shortcut is to use a cosmetic texture.
! asked this same question a few months ago. Here is what I did to show it within our guarding. Its not to scale, because I just wanted a representation of expanded metal. I made a Design Table to cut out what was needed per the guarding. I started with a 48" x 120" and just used the same feature to cutout what was needed.
I also needed a rolled piece, but this time I just made a rolled sheet and cut out a portion using an Expanded metal sketch. The reason for only using a portion was so it didn't kill my assembly.
I have attached both files in this post.
SW needs to make a file that can by customized without it the file being huge. The guarding part is over 100MB after I add the above DT.
Hope this helps,

I did this once in Pro|E but this is pretty generic if you must have the offset.
Start with determining the angle of each "wave". This can be managed with a sketch of the side view.
Next, create a wave extrusion on a plane angle per the sketch. Wave - wwwwwwwwwwwwww Plane angle /
Now pattern the wavy feature once in x and y to accomplish the offset. Be sure they merge.
Then pattern both features to the desired plate size and trim the edges to the finished size.
Here is one with additional processing...
