Bulk stainless steel banding and clips are stocked in 5/8" and 3/4" sizes, with 1/2" available by special order.  The banding is .030" thick and sold in 100' rolls.  The clips, or buckles as their sometimes called, are available in boxes and/or pouches of 100.  Stainless steel banding is widely used with flared or straight saddles to install signage to large diameter poles or posts, but does require the use of a banding tool to install, and components must be purchased in bulk.
