Wright Tank stocks three sizes of gravel rings:
Our rings are approximately 6” high and come in a coil that is roughly 24” in diameter. They are pre-drilled with two bolts holding the coil together. On the job site, you simply take the bolts out and uncoil the ring. Then, you reinstall the bolts in the last holes. At this point, you make the ring round and level. Our standard ring is made out of 16-gauge galvanized steel.
(Note: We can make rings of up to 24″ in height and of a larger diameter.)
We can also build rings 16 gauge all the way down to 10 gauge.
Stakes for the outside edges of the ring are also available.
