Abstract: A modular fence assembly constructed of grade ASTM A-36 to G-50 hardness pre-painted galvanized steel sheet metal with an ASTM A-40 to G-90 coating thickness. The modular fence assembly is solid in construction and is not easily overcome by bolt cutters, axes, or sledge hammers nor is it easily climbable. The posts of the present modular fence assembly have built-in depth markers to ensure uniformity during installation and have anchors that help withstand harsh weather, heavy impact, and prevent them from being pulled out from the ground by trespassers.
