Here's the diff...the Tposts will last a long, long time, 20 years here so far.Hi @aart
I don't know what solid forged Tposts are. We are unsupported community garden...we have to pay for whatever we need. Our fence posts are the metal kind typically used for snow fence. The are a variety...contributed by members, scarfed off of Criaig's list, etc. They have lasted surprisingly well the past 8 years. I have another 13 newish ones, another member can contribute another 6 or so. Does this answer your question?
The other not so much, maybe, depends on the gauge(thickness) of the metal used.
