Anotace textu normy ASTM F3151-17(2025) :

This specification establishes the material requirements and installation procedures for driven steel post drive anchor systems. It provides an alternative to the use of concrete footings for the purpose of installing steel post frameworks to support chain link, expanded metal, welded wire mesh, wood, ornamental, rigid PVC, and composite fence. The drive anchor clamp bracket—the pressed steel fitting that secures the drive anchors to the post—shall be pressed steel, minimum of 11 ga. x 1 in. wide, minimum 1.2 oz/ft² hot dipped zinc coating. The bracket shall be secured using 3/8 in. diameter bolts. Industrial/commercial applications require all driven steel anchors, including round or square sections, to have equal or greater strength characteristics as the historical 1 1/2 in. x 1 1/2 in. x 1/8 in. steel angle irons. Whichever shape is chosen, the yield strength shall be 35,000 psi, maximum bending moment 6,462 lb/in., minimum 1.2 oz/ft² zinc coating, and gripping surface area 3 in.².
