The prison wall is mysterious, but it is actually very common. The wall is built of cement and ordinary red bricks. The thickness is extraordinary. The underlying foundation is much deeper, which prevents prisoners from digging holes to escape. The wall of the prison is divided into two layers. In the middle of the two floors is a “precautionary area.†The armed police watching the patrol stand on the outer wall. The inner wall is generally equipped with a blade gill net, and a sharp blade, high-tension galvanized steel wire or stainless steel wire is used as a repelling device formed by combining a hot-dip galvanized steel plate or a stainless steel plate. Because the unique shape of the knife gill net is not easy to touch, it can achieve excellent protective isolation. There is a grid outside the fence and the voltage is very high, which can kill people. It is almost impossible to escape.
Another type of prison wall network is mainly composed of snake belly type high-strength blade barbed wire, Y-shaped square (circular) tube high carbon steel welded mesh, v-wire welded wire mesh and security anti-theft connection.
