The windmills are constructed of galvanized steel, but do have to be assembled, which I hear only takes a few hours for the smaller ones and a bit longer for the larger ones.  The powder coated windmills usually take a few weeks to ship, while the standard un painted versions usually ship in a few days.  These windmills can also be retrofitted down the road to provide aeration to ponds are to pump water from wells, so they are very practical as well.

Just thought this was a cool thing felow Buckeyes might enjoy.
