A wire rope barrier that uses a cable hanger or hangers that act to retain a cable against a post yet release the cable from the post in a tuneable and controllable manner when the barrier is subjected to an impact force and displacement such as from a vehicle collision. The hanger comprises at least two legs, each with a different axis of rotation relative to the post on which the legs are hooked, the result being that the hanger in an impact releases the post from the cable at a predetermined loading and in a controllable and repeatable manner. In one embodiment described, the hanger legs may extend from a cable holding portion, the legs attaching to opposing sides of the post. In a further embodiment, when a predetermined impact force is imposed on the barrier, at least one hanger releases a retained cable when the at least one leg or a part thereof deforms allowing the cable holding portion to in turn release the cable.

ABSTRACT An apparatus (100) for projecting a stay wire (7) across a plurality of line wires (2) in a fence mesh forming machine. The apparatus (100) has at least two rollers (109) defining a wire travel path (W) between the rollers and arranged to contact the wire (7) and move the wire along the wire travel path (W) upon rotation of the rollers (109). At least one of the rollers (109) is arranged to be directly driven by a respective motor (115). Preferably, each of the rollers (109) is arranged to be directly driven by a respective motor (115).

The present invention relates to a method for pre-treating one or more galvanized fence panels to be coated, wherein the one or more galvanized fence panels are sequentially immersed in baths in a suspended state, wherein the method comprises the following sequential steps: degreasing, whereby the fence panels are immersed in a degreasing bath containing a degreasing agent; rinsing, wherein the fence panels are immersed in a first rinse bath comprising water; pickling, whereby the fence panels are immersed in two successive pickling baths containing pickling agents; rinsing, wherein the fence panels are immersed in a second rinse bath comprising water; demi-rinsing, whereby the fence panels are immersed in a demi-rinse bath containing demineralized water; applying an adhesion layer, wherein the fence panels are immersed in a polymer bath; and wherein the fence panels are subsequently dried in an oven, and wherein the pickling agents comprise hydrogen fluoride and phosphoric acid, in a ratio between 1/320 and 1/80.
