1、Designation: F1043 18Standard Specification forStrength and Protective Coatings on Steel Industrial FenceFramework1This standard is issued under the fixed designation F1043; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
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, s

Factors toconsider when determining windload
5、include 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
6、units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-izati
