"What is the best plate thickness to use for HHO ?" 

A good question. Often, what is the best and what you can get are two different things. But given a choice, and assuming it is available, most HHO companies are using 20 gauge or 0.036 inches thick. It seems to have enough strength to resist bending and enough longevity to satisfy customers. 22 gauge is slightly thinner, at 0.030 inches. It costs a few dollars less per square foot, than 20 gauge, but is more susceptible to the edges bending with some methods of cutting. 19 gauge and 1 mm are good alternative choices, if you can find them. I used 16 gauge with my Tube cell, because the strength was needed in order to avoid getting the tubes out of round. They had to be perfect in order to create equal spacing inside - from tube to tube . The strength of the flat plate is important, but in most cases, it does not need to be as strong as 16 gauge. The thicker the steel, the harder it is to cut and drill (tooling).

Below, I have listed some gauges that are being used. They are all suitable for HHO. The thicker plates will last longer than the long lasting thinner plates. I like the way I said that. Actually, how long they will last is up to the user. If your amperage exceeds the Current Density capability of the plate size, then you are to blame for their deterioration.
