robust wire and welded joints make cutting very difficult. WireWall welded security mesh has been the standard in Europe for over 20 years for security barrier applications where high security protection is a must. Developed in the 1980's by the British Prison Service, welded security fencing is routinely used in England and elsewhere in Europe as a security barrier to protect valued assets and to protect the general population from the bad guys. Since the early 1990's, Riverdale Mills, America's leading manufacturer of welded wire products, has been making high quality wire mesh fencing, called "WireWall", right here in Northbridge, Massachusetts.
