Standard Guide for Design and Construction of Ornamental Steel Picket Fence Systems for Security Purposes
SIGNIFICANCE AND USE
4.1 Ornamental steel picket fence systems can be designed to provide greater levels of security by selecting styles and configurations that increase the difficulty to penetrate and in turn increase delay time. Some examples include: increasing the height of the fence, using ornamental picket styles that curve outward to form a parapet on the attack side of the fence, and decreasing the spacing between vertical pickets.
4.2 Security hardening of ornamental steel picket fence systems can be achieved by adding fence security accessories (that is, barbed wire to the top; barbed tape to the top, side or bottom of the fence; or spiked railing supplements along the top rail) or by attaching supplemental security fence fill materials (that is, expanded metal, barbed tape mesh, welded wire mesh, or chain-link mini-mesh fabric). Slats or screening panels can be inserted to restrict visibility when required.
4.3 Multiple fence lines can be installed to create isolation zones that enhance the ability to patrol or visually monitor the area.
4.4 Anti-ram cable systems may be added to resist vehicle penetration into a protected perimeter.
SCOPE
1.1 This guide provides the material and installation standards for selection in the design of an ornamental steel picket fence system for security applications. The proper material selection and system installation and layout can substantially increase the difficulty to penetrate; thereby, increasing the intrusion delay time.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Terms defined in Specifications F2408 and F2589 shall also apply to ornamental steel picket fence systems under the
jurisdiction of this guide.
3.2 Terms defined in Terminology F1379 shall apply to the use of barbed tape obstacles referenced in this guide.
3.3 Definitions of Terms Specific to This Standard:
3.3.1 fence security accessory—an accessory product added at the extremities of an ornamental steel picket security fence
system to broaden its coverage range and increase the time and difficulty necessary to breach the system (for example, barbed wire,
barbed tape, spiked railing supplements, etc.).
3.3.2 supplemental security fence fill—a secondary fence filler material (for example, expanded metal, welded wire mesh,
chain-link mini-mesh fabric, etc.) attached to or integrated with the vertical pickets of the ornamental steel picket fence system.
4. Significance and Use
4.1 Ornamental steel picket fence systems can be designed to provide greater levels of security by selecting styles and
configurations that increase the difficulty to penetrate and in turn increase delay time. Some examples include: increasing the height
of the fence, using ornamental picket styles that curve outward to form a parapet on the attack side of the fence, and decreasing
the spacing between vertical pickets.
4.2 Security hardening of ornamental steel picket fence systems can be achieved by adding fence security accessories (that is,
barbed wire to the top; barbed tape to the top, side or bottom of the fence; or spiked railing supplements along the top rail) or by
attaching supplemental security fence fill materials (that is, expanded metal, barbed tape mesh, welded wire mesh, or chain-link
mini-mesh fabric). Slats or screening panels can be inserted to restrict visibility when required.
4.3 Multiple fence lines can be installed to create isolation zones that enhance the ability to patrol or visually monitor the area.
4.4 Anti-ram cable systems may be added to resist vehicle penetration into a protected perimeter.
5. Part 1—General
5.1 List the scope of work included; the performance requirements of the overall project security design criteria; the
performance design criteria for the fence system, referenced contract documents, fence design and detail drawings, material
specifications, related site work, site drawings with the specific fence layout, product and data submittals, certifications, site
preparation, contractor qualifications, warranties and the fence integration with other security products.
5.1.1 Fence placement can be critical and should be well thought out and defined by the contract specifications and drawings.
Placement should be coordinated with the grading plan to ensure it does not inhibit drainage flow or cause debris buildup.
5.1.2 Consideration should be given to the fence location to provide the proper offset to protect a building or provide a clear
zone from trees, underbrush, buildings and structures. Qualifying federal building sites require specified fence set back distances
from the building in compliance with the DoD Minimum Antiterrorism Standards for Buildings, UFC 4-010-01.
5.1.3 Consideration should be given during design of the fence to ensure it will properly support the application of added
intrusion detection devices. An integrated system using lighting with video surveillance requires a specific fence layout, for
example, the fence must be located to avoid blocking the view or reduce shadows.
5.1.4 Signage posted along the fence line should always be a consideration.
6. Material Requirements
6.1 Tubular Picket Ornamental Fence System:
6.1.1 Structural components of tubular picket ornamental fence systems shall meet the material and coating requirements of
Specification F2408 or F2589, whichever is applicable.
6.1.2 There are multiple panel and picket design configurations; those recommended for security fence applications are listed
in Table 1.
6.1.3 Because ornamental steel picket fence systems designed for increased security levels are generally taller and heavier than
fences for other applications, and, because they frequently are hardened by the addition of supplemental expanded metal, welded
wire, or chain-link fill, wind resistance is amplified. Fence system designs should be selected to meet the anticipated wind loads
based on the site geographical location, soil strength and weather conditions.
6.2 Fence Security Accessories : Accessories:
6.2.1 Barbed Wire—When barbed wire is specified, It is recommended that polymer coated barbed wire in accordance with
Specification F1665, Type II spacing at 3 in. (76 mm) on center be selected. The color should match the color of the ornamental
fence, if possible to match the aesthetics of the fence system. Metallic coated carbon steel barbed wire, high security grade in
accordance with Specification A121, is also permissible.
6.2.2 Barbed Tape Obstacles—When barbed tape is specified, select the diameter, design and configuration in accordance with
Specification F1910.
