A modular fencing panel (100) is disclose. The modular panel (100) includes a frame composed of two substantially vertical members (stiles) (101a, 101b) and two horizontal members (rails) (101c, 101d). Each of the members (101a, 101b, 101c, 101d) may also be provided with a plurality of apertures (102) to allow for the interconnection of the panel with an adjacent panel or support structure. To complete the panels construction a security mesh (103) (shown here in partial section in the interests of clarity) such as steel mesh, chain wire etc is fixed to the external face (105) of the panel (100), while a series of horizontal, smooth, corrosion resistant, high tensile alloy wires (104) forming the electric fence line are positioned adjacent the internal face (106) of the panel.
