Harsco Corporation announced a new product introduction for the physical protection of critical infrastructure and high security operating facilities. GrateGuard™ began as a solution to a common security concern: How best to provide a high strength security barrier physically capable of withstanding a concerted intrusion effort? Current market offerings of chain link fencing, ornamental iron or aluminum, welded wire and expanded metal all provide a visual deterrent, but each lacks in the critical ability to thwart a well-equipped breach.
