Grace:
Welding galvanized steel is not a good idea; toxic zinc fumes. What is a "building collar?" Your immunity lab must be within a shielded enclosure, so it should already be safety grounded. Since you will be doing ESD testing INSIDE the enclosure, you will not have to be draining any charges of the exterior of that chamber. Metal sheet material for where; the chamber walls, the ground plane table?

We plan to layout a L shape ground plane in the 24' x 18' area for ESD, etc. tests. The corner of the L shape is right next to a 10" wide building collar. Is a ground strap tied to the collar good enough? Do we need (copper) ground rods? If yes, what is the minimum length (deep)? What is the recommended space between rods? How to choose metal sheet material (galvanized steel, stainless steel, etc.)? When weldering the metal sheet, is there anything that need to be cautious? Thank you very much and look forward to your help.
