Deineria, I don't have any pics handy. I could take some, but all they are is lengths of round steel that are 1/2" in diameter. Hot rolled is just the method of forming the steel. Cold rolled is basically the same, but marginally "cleaner". Cold is usually more expensive than hot and the minor difference in the finish only matters if you are welding.
If you really want pics, post again and I will take some. But, really, just picture round pieces of steel sticking up from the ground. Nothing fancy at all.
