Typical 99.9% Wire-Free Rubber Mulch
99.9% Wire-Free recycled rubber mulches sound pretty wire-free, but often they really aren't. In many cases, there can be up to 20-30 exposed rigid steel wires per lb. from the steel-belted radial tires they're made from, and not properly screened. This photo shows pieces from a sample of less than 1-1/2 lbs. of playground product from one of the larger rubber mulch manufacturers in the U.S., with wires up to over 1" in length that can obviously cause cuts and other injuries, unlike recycled rubber mulches made from bias-ply tires or virgin rubber non-recycled rubber mulches.
