1.1 本规范涵盖了工业钢栅栏框架的强度和保护涂层要求。预期用途适用于所有类型的围栏，包括但不限于链节、膨胀金属、焊接和编织的钢丝网、PVC和木材。有关立柱间距要求，请咨询围栏产品制造商。链节围栏的立柱间距不得超过10英尺（有关更多信息，请参阅CLFMI指南WLG2445。） 1.1.1 关于风荷载的注意事项- 如果需要对围栏添加添加剂，如挡风玻璃、插件或标志，建议使用更坚固的框架和配件，以减少- 立柱的中心间距，或添加后支撑。确定风荷载时要考虑的因素包括使用的筛分材料类型、覆盖的围栏面积以及当地的风力条件。 1.2 立柱和导轨可以具有满足本文要求的任何横截面形状。这些形状可以成形和焊接、冷成形、热轧或挤压。 1.3 以英寸-磅单位表示的数值应视为标准值。括号中给出的数值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers the strength and protective coating requirements for industrial steel fence framework. The intended use is for all types of fence, including but not limited to, chain link, expanded metal, wire mesh both welded and woven, PVC, and wood. Consult fencing product manufacturer for post spacing requirements. Post spacings for chain link fence are not to exceed 10 ft. (For additional information, see CLFMI Guide WLG2445.) 1.1.1 Caution Regarding Windload— If additives to the fence, such as windscreen, inserts, or signage are required, it is advisable to use stronger framework and fittings, to reduce the on-center spacing of posts, or to add back bracing. Factors to consider when determining windload include the type of screening material to be used, area of fence to be covered, and local wind conditions. 1.2 Posts and rails may have any cross-sectional shape meeting the requirements herein. The shapes may be formed and welded, cold formed, hot rolled, or extruded. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
