Sorry it took me so long to get back - we have been busy with school startup, etc. Anyways, it is 2"x10' lengths welded. MUCH nicer than the original iron pipe we used which sagged and was heaving to crank. This moves so slick that sometimes I have to watch that I don't unreel too fast (leaving the cover in a pile on the ground) I think maybe I actually do have some pictures somewhere on the site in an old post, not sure if it shows it very well or not...I'll have to look again. If not, I will sure post again. It was so simple to build and the price was right. Just gotta know how to weld or know someone who does - DH has a nice portable wirefeed welder so he got supplies and the whole thing done in less time it would have taken to get one shipped in from a store - one day.
