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.

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
