I am running a 6" and a 4" Nema 12 wireway from the panel to the equipment. They are
at 10 Feet elevation and it is 12' from the panel to the equipment.
How often does it need to be supported?
Is it maximum of every 10 feet allowed like conduit?

I plan on using as 3" mild steel square tube from the floor to the wireway and fasten the wireway on a plate welded to the top of the 3" square tube. This support will be at the mid point (approx 6') between the panel and the equipment.
