Concertina Razor Wire specific requirements for the perimeter

Concertina Razor Wire specific requirements for the perimeter:

The requirements for the barbed roller cage are more specific. The new standard provides more specific and detailed regulations on the structure and structure of physical fences (walls):

(1) The spatial structure indicators of anti-climbing facilities such as barbed roller cages or blades are clearly defined for the top of the fence (wall).

(2) The requirement for the net height of the inner and outer sides of the physical enclosure to be no less than 2.5 m is more explicit. It should also be noted that the concept of the net height and the boundary height in the boundary is not the height of the boundary itself, but the height from the highest point in the 3m range on the inside and outside of the boundary to the top of the boundary.

(3) For the case where the building constitutes a part of the boundary, the new standard specifies the conditions in which the building forms part of the boundary and the internal wall of the building forms part of the boundary.

(4) The requirements of some technical indicators of the fence are optimized, such as the increase of the anti-corrosion period from 5 years to 8 years. In addition, in addition to the several types of fences (walls) listed, for other forms of fences, the new standard should be modified to be available after filing with the competent department of civil aviation administration.
