1. A method for assembly of a thermoplastic fencing construction comprising:

  • A. providing a structural fence member of thermoplastic material with a bore extending longitudinally therethrough and defining a bore opening therein and further defining an inner wall surface extending around and defining the bore and an outer wall surface oppositely positioned from the inner wall surface and facing outwardly with respect thereto with a structural securement zone defined on the inner wall surface for facilitating securement with respect thereto;

    B. providing a capping fence member of thermoplastic material and defining a capping securement zone thereon for placement adjacent to the structural securement zone on the inner wall surface of the structural fence member for allowing mutual securement together by ultrasonic welding together;

    C. providing a plurality of welding ribs to facilitate ultrasonic welding between the structural securement zone of the structural fence member and the capping securement zone of the capping fence member;

    D. positioning of the capping fence member extending through the bore opening and into the bore defined in the structural fence member with the capping securement zone in registration with respect to the structural securement zone and with the welding ribs positioned between the capping securement zone and the structural securement zone; and

    E. securing of the capping fence member to the structural fence member by ultrasonically welding for melting of the welding ribs positioned therebetween to affix the capping securement zone with respect to the structural securement zone.
