Strength Requirements5.1 It is the intent of this specification to permit thecontinuance of historically proved practice in the installation ofchain link fence systems
21、, and to provide strength requirementsfor alternative shapes and materials. Two categories are de-scribed. Heavy industrial fence represents the most rigid andmechanically durable of the commonly installed framework.Light industrial/commercial fence, as provided herein, exhibitsapproximately 80 % of
22、 the load bearing capability of heavyindustrial fence. The summary requirements and options forheavy industrial fence are given in Table 3 and those of lightindustrial/commercial fence in Table 4.5.2 Historical PracticeExperience has shown that galva-nized steel performs satisfactorily as fence post
23、s and rails iffurnished to the standard weight (Schedule 40) and nominalsizes listed in Specification F 1083. Therefore, fence posts andrails consisting of standard weight (Schedule 40) galvanizedsteel in the nominal sizes and weight per foot listed inSpecification F 1083 shall be considered in comp
