WireWall®
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.
WireWall® is constructed from premium steel that is galvanized after welding with a heavy coating of pure zinc that protects the wire from corrosion. WireWall® is also available with our proprietary marine grade PVC coating that we fuse bond to the wire providing ultimate protection in any environment. Our facility handles every stage of the manufacturing process using rigorous testing methods to ensure our 358 security mesh, WireWall®, meets the appropriate ASTM standards. Riverdale also has the ability to meet the requirements of US Department of Transportation “Buy America” upon request.
