2、of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the strength and protectivecoating requirements for industrial steel fence framework. The
3、intended use is for all types of fence, including but not limitedto, chain link, expanded metal, wire mesh both welded andwoven, PVC and wood. Consult fencing product manufacturerfor post spacing requirements. Post spacings for chain linkfence are not to exceed 10 ft. (For additional information, se

Factors toconsider when determining windload i
5、nclude the type ofscreening material to be used, area of fence to be covered andlocal wind conditions.1.2 Posts and rails may have any cross-sectional shapemeeting the requirements herein. The shapes may be formedand welded, cold formed, hot rolled, or extruded.1.3 The values stated in inch-pound un

Strength Requirements5.1 It is the intent of this specification to permit thecontinuance of historically proven practice in the installation offence systems, and to provide strength requirements for alter-native shapes and materi
20、als. Two categories are described.Heavy Industrial fence represents the most rigid and mechani-cally durable of the commonly installed framework. LightIndustrial/Commercial fence, as provided herein, exhibits 80 %of the load bearing capability of heavy industrial fence. Thesummary requirements and o
21、ptions for Heavy Industrial fenceand those of Light Industrial/Commercial Fence are given inTable 3.5.2 Historical PracticeExperience has shown that galva-nized steel performs satisfactorily as fence posts and rails iffurnished to the standard weight (Schedule 40, Regular Grade,30,000 psi) and nomin
