A fearsome-looking new “anti-climb security system” has been installed at the top of the steel fencing of the main Cardiff Bay Barrage water outlet.
The system comprises a row of rotating metal vanes which are designed to make life difficult for people attempting to climb over the fence and – perhaps – jump into the briny below.
It’s called a Vandguard Rotating Anti Climb Guard system. The bladed rotors are installed in pairs with 13 vanes being lined up in each one metre length of the barrier
Vandguard says “The interlocked pairs of vanes form a bulky and discouraging curved six pronged barrier some 400mm in overall diameter, which is designed to be difficult to climb over, without the risk of causing life threatening injury.”
The all-weather blades are made from high tensile aluminium alloy which is rustproof. Vandgard Anti-Climb is described as a “robust security fencing and a fearsome defence for all situations where serious vandalism or theft is likely. ”
In the unlikely event that any fence-climber does make it over this formidable barrier they would fall not into the sea – but into horizontal netting stretched taut beneath the level of the barrage wall .
