Let me answer that this way: I've still got a couple of trees about the size of the (3) that got blown over. If one of those went down in that storm it could have landed on my RC.Is it a reason not to plant them and live in a desert? I have hundreds of trees on my land(bit over 4 acres) and it's a true PITA to mow around them but it's worth the effort.
The green ones are actually powder coated, I have been away too long, not sure if white is powder, or a painted style. but the jury is still out on what is best. Thats for outside exposed concrete that gets wet. I think I would go for galvanized. But under a garage, I would go with the cheapest, not likely to see the wet dry cycles that out door stuff will.Generally it's some sort of plasti-dip / epoxy / plastic coating and the general idea is rust prevention for the rebar.
He would have been the one coordinating the poles, and concrete work, cannot blame anyone else.My poles are in the ground with the concrete poured around them. I wonder if the general is going to come back and see this and ask why the poles didn't go in first. This could be fun to watch. LOL
