One good thing about a steel pier, you can route your electrical and other cables through it, if you so wish and that'll get them out of the way.
I suppose what your choice is will depend on cost and just how enthusiastic you are about knocking one up. Also, the time allowed for construction will be a factor.

Thanks Carl. Time allowed for construction ...
Ive been waiting to start this for a good while now mate ... So Im not concerned about how long any part of the process takes to come together ... everything that is done is one step closer to operational !!!
Good point about the cure time though. Super critical that nothing is allowed to come into contact with it. I guess that the pier would have to be done at the same time as the footing to give it the best overall structural strength too. I mean if it was poured after the footing there would always be a layer of weakness at the join wouldnt there, even tho there would be reinforcing coming up the pier from the footing.
