1.1本指南提供了用于安全应用的装饰性钢栅栏系统设计中选择的材料和安装标准。适当的材料选择和系统安装和布局可以大大增加穿透的难度；因此，增加了入侵延迟时间。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 装饰性钢桩围栏系统的设计可以通过选择增加穿透难度并进而增加延迟时间的样式和配置来提供更高级别的安全性。例如:增加围栏的高度，使用向外弯曲的装饰性尖桩样式，在围栏的攻击侧形成女儿墙，以及减少垂直尖桩之间的间距。 通过添加围栏安全附件（即，顶部有刺铁丝网； 围栏顶部、侧面或底部的带刺胶带；或沿顶部栏杆添加尖刺栏杆）或附加附加安全围栏填充材料（即，膨胀金属、带刺胶带网、焊接钢丝网或链环迷你网织物）。必要时，可以插入板条或屏蔽板以限制能见度。 可以安装多条围栏线来创建隔离区，以增强巡逻或视觉监控该区域的能力。 可以添加防撞击电缆系统，以抵抗车辆进入受保护的周边。

1.1 This guide provides the material and installation standards for selection in the design of an ornamental steel picket fence system for security applications. The proper material selection and system installation and layout can substantially increase the difficulty to penetrate; thereby, increasing the intrusion delay time. 1.2 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== Ornamental steel picket fence systems can be designed to provide greater levels of security by selecting styles and configurations that increase the difficulty to penetrate and in turn increase delay time. Some examples include: increasing the height of the fence, using ornamental picket styles that curve outward to form a parapet on the attack side of the fence, and decreasing the spacing between vertical pickets. Security hardening of ornamental steel picket fence systems can be achieved by adding fence security accessories (that is, barbed wire to the top; barbed tape to the top, side or bottom of the fence; or spiked railing supplements along the top rail) or by attaching supplemental security fence fill materials (that is, expanded metal, barbed tape mesh, welded wire mesh, or chain-link mini-mesh fabric). Slats or screening panels can be inserted to restrict visibility when required. Multiple fence lines can be installed to create isolation zones that enhance the ability to patrol or visually monitor the area. Anti-ram cable systems may be added to resist vehicle penetration into a protected perimeter.
