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
