17、Standards for Buildings43. Terminology3.1 Definitions, see Terminology F552.4. Summary of Practice4.1 Chain link fence systems can be designed to provide greater levels of security by selecting products and configurations thatincrease the difficulty to penetrate and in turn increase delay time. Some
18、 examples; increase the height of the fence, theconfiguration of chain link mesh size and wire gauge, securing the bottom of the fence by means of bottom rail, burying the chainlink mesh, adding barbed wire to the top or barbed tape to the top, side or bottom of the fence, selecting stronger framewo
19、rk, addingmultiple fence lines to create isolation zones, adding slats to the fencing to restrict visibility when required, and adding anti-ramcable systems to resist vehicle penetration into a protected perimeter.5.

22、oes not inhibit drainage flow by location or 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 clearzone from trees, underbrush, buildings and structures. Qualifying Federal building sites require specified fence
23、set back distancesfrom the building in compliance with the DoD Minimum Antiterrorism Standards for Buildings, UFC 4-040-01.5.1.3 Consideration should be given during design of the fence to ensure it will properly support the application of addedintrusion detection devices. An integrated system using
24、 lighting with video surveillance requires a specific fence layout, forexample, 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.5.1.5 Review Specification F1712 for security chain link material recommen

28、.Select the color as listed in Specification F934.6.2 Fence Framework:6.2.1 Line PostsFences designed to provide increased security levels are generally of greater heights and utilize smaller meshsizes, both of these factors result in added wind load resistance. Line post selection and the spacing o
29、f the posts should be designedto meet the anticipated wind loads based on the site geographical location and weather conditions. Increased post sizes or specificpost spacing may be required to compensate for wind loading or increased security. The Chain Link Fence ManufacturersInstitutes, Guide for
30、the Selection of Line Posts and their Spacing, WLG 2445, guides the designer through the process to selectthe post size and post spacing.
