Significance and Use4.1 Ornamental steel picket fence systems can be d

16、esignedto provide greater levels of security by selecting styles andconfigurations that increase the difficulty to penetrate and inturn increase delay time. Some examples include: increasingthe height of the fence, using ornamental picket styles thatcurve outward to form a parapet on the attack side

17、 of the fence,and decreasing the spacing between vertical pickets.4.2 Security hardening of ornamental steel picket fencesystems can be achieved by adding fence security accessories(that is, barbed wire to the top; barbed tape to the top, side orbottom of the fence; or spiked railing supplements alo

18、ng thetop rail) or by attaching supplemental security fence fillmaterials (that is, expanded metal, barbed tape mesh, weldedwire mesh, or chain-link mini-mesh fabric). Slats or screeningpanels can be inserted to restrict visibility when required.4.3 Multiple fence lines can be installed to create is

19、olationzones that enhance the ability to patrol or visually monitor thearea.4.4 Anti-ram cable systems may be added to resist vehiclepenetration into a protected perimeter.5.

Placement should be coordinated with the gradingplan to ensure it does not inhibit drainage flow or cause debrisbui

22、ldup.5.1.2 Consideration should be given to the fence location toprovide the proper offset to protect a building or provide a clearzone from trees, underbrush, buildings and structures. Quali-fying federal building sites require specified fence set backdistances from the building in compliance with

23、the DoDMinimum Antiterrorism Standards for Buildings, UFC 4-010-01.5.1.3 Consideration should be given during design of thefence to ensure it will properly support the application of addedintrusion detection devices. An integrated system using light-ing with video surveillance requires a specific fe

26、e-signed for increased security levels are generally taller andheavier than fences for other applications, and, because theyfrequently are hardened by the addition of supplementalexpanded metal, welded wire, or chain-link fill, wind resistanceis amplified. Fence system designs should be selected to

27、meetthe anticipated wind loads based on the site geographicallocation, soil strength and weather conditions.6.2 Fence Security Accessories:6.2.1 Barbed WireWhen barbed wire is specified, It isrecommended that polymer coated barbed wire in accordancewith Specification F1665, Type II spacing at 3 in.
