Do you want the doors below the tank to match your cabinets? I am assuming 2 pair of doors. If so, you can use a center post and wood is not a problem. It is also much cheaper. The sump will need to fit in one side, so you can't have a 5' long sump, but that works fine on my 180. The other side is full of equipment and a refugium.
Using steel can be a pain because you need to make sure the stand is protected from the salt water. Not a big deal in an open stand where you can see rust occur and attend to it, but in a built in situation where some parts of the stand will never be seen, you need to make sure the waterproofing is 100% as you won't see the damage until it is to late.
