Abstract: A crash fence assembly (10) including: first and second uprights (12) locatable spaced from each other upstanding from the ground; and a first fence panel (14) extendible between the first and second uprights (12), the first fence panel (14) comprising: one or more barrier elements (16A, 16B) configured to define a barrier (17) between the first and second uprights (12); a first cross-panel member (18) configured to span between the first and second uprights (12); a first upstanding brace (19) configured to be secured to the first cross-panel member (18) at least a first span distance from the first upright (12) to distribute impact load, wherein the first upstanding brace (19) has a greater stiffness than the or each barrier element (16A, 16B).

Abstract: A palisade security fencing assembly 10 with a plurality of spaced upright posts 12, with cross bars 16A, B and C extending therebetween. A plurality of pale members 18 are mounted to the cross bars 16A, B and C. The pale members 18 are profiled to define a recess facing the cross bars 16A, B and C. The pale members 18 are mounted to the cross bars 16A, B, C by rivet arrangements 36, with a front end 38 of the rivet arrangements 36 located in the recess, and a rear end 40 of the rivet arrangement 36 on the rear side of the cross bar 16A, B and C, thereby substantially preventing unauthorised access to the rivet arrangements 36.

Abstract: A security gate apparatus (10) with first and second buttress assemblies (12, 14) and a barrier member (16) slidably movable along the track 68 between a closed position extending between the assemblies (12, 14), and an open position clear of the assembly (14). Each assembly (12, 14) includes upstanding members (18, 20, 54, 56) connected respectively by a link member (22), with at least some of the members (18, 20, 54, 56 and 22) being filled in use by concrete. The gate being locatable respectively between the upstanding members (18 and 20) and the upstanding members (54, 56).
