Light Industrial/Commercialfence, as provided herein, exhibits 80 % of the load bearing capability of heavy industrial fence. The summary requirements andoptions
22、for Heavy Industrial fence and those of Light Industrial/Commercial Fence are given in Table 3.5.2 Historical PracticeExperience has shown that galvanized steel performs satisfactorily as fence posts and rails if furnishedto the standard weight (Schedule 40, Regular Grade, 30,000 psi) and nominal si
