They also had a problem with the large bolts that hold the supports together. It turns out that even though the bolts were made in the USA, they were made from galvanized steel, which doesn’t play well with salt air. I don’t know how that one was resolved; hopefully, they replaced them with something more durable.
“they were made from galvanized steel, which doesn’t play well with salt air.”
Galvanizing is a coating for steel. It’s composed of zinc which is deposited over the steel. Bolts are not made of zinc. Properly applied it will resist salt air quite well for some time.
