You ask a really strong person to break them apart. Seriously they do come apart it’s just a little hard
Per packaging it’s 1’ diameter for each section. I.e. 3 sections = 3 ‘ diameter I wouldn’t recommend less than a 2’ diameter
Yes. Very hard paint and I make sure I don't abrade or scratch the covering to allow rust. I have made over 24 rings with this product and never had a problem. I have drilled through the section and stake to bolt them together but this was a personal preference and not a necessity. To protect, I hit them with corresponding brown primer in a spay can.
I have tried to make a 24" diameter circle but the metal is so rigid (good thing) that it never worked. Did purchase a piece of 24" PVC sewage pipe from pipe supplier and cut segments from that.
COL-MET manufacturing is close to me and I have asked. Just green and brown. If wanting black, use a good paint to adhere. Did not need to prime to change color.
The curved 4' sections and the straight 4' sections are actually the same pieces, the tree ring sections are just curved. So yes, the curved and straight pieces will matchup at the ends, but because of the curved ends it would be easier to use the straight 4' sections and bend those as opposed to try and straighten the curved ends.
The sections are actually 4" in length, so 7 sections (28' total) would make a ring that is almost 9 feet across.
Use two adjustable pliers to twist them apart.
4 Tree Ring Sections will make a roughly 4' diameter circle and 5 sections will make a roughly 5' diameter circle. You could use 5 pieces and overlap the last two pieces a bit, instead of connecting them end-to-end and use a Splicing Stake (SKU# 272311) to secure the overlap area.
The description of a “1ft Tree Ring” is a bit confusing. The Tree Ring Sections are made from curved 4ft sections and they are designed to be used in groups of 3, 4 or 5 to yield a roughly 3’, 4’ or 5’ diameter circle. Once the 8” overlap is accounted for each piece offers 3’ 8” of circumference in each respective circle.
