Security fencing is generally made out of steel or aluminium for superior strength. These fences are designed to keep intruders out and can come with barbed wire or spiked tops for extra security.
They can be constructed with a variety of non-climbable materials. Recent advances have allowed for more aesthetically appealing designs. Being a robust fence, they have a real presence, and powder coating improves their appearance.
The typical height of a security fence is 2.5-3m, but can be much higher if required.
