WireWall® by Riverdale Mills is a virtually impenetrable, high security fencing material most often requested by security and safety experts, architects and construction management consultants. WireWall®, a 358 security mesh, is nearly impossible to scale, rust proof and corrosion resistant, provides unmatched security and protection and is cost-effective. Riverdale has been manufacturing WireWall® at our Massachusetts, USA factory for over thirty years; WireWall® is now used in over 1,000 locations around the globe to protect embassies, borders, airports, power plants, prisons and military bases.
