- Military bases, confidential military sites, and restricted military areas
- High-security government buildings, border checkpoints, and confidential office areas
- Power stations, nuclear facilities, and other key energy supply sites
- High-security warehouses, logistics bases, and important industrial sites
FAQ
Q1: What is the core anti-climb feature of the prison security fence?
A: It uses 358 anti-climb mesh with an aperture of 76.2mm×12.7mm, which is too small for hands or feet to grasp, making climbing impossible. It is matched with BTO-22 razor wire to form a double anti-climb protection.
Q2: How long is the service life of the production?
A: It adopts hot-dip galvanizing + spraying process, with a zinc coating of ≥80μm. Its service life is over 15 years in general areas, and it can reach 20 years in coastal areas with special anti-corrosion treatment.
Q3: Can the production be customized for high-security projects?
A: Yes.It has a high-security version with a total height of ≥4.5m, smaller mesh holes (50mm×50mm), and double-layer spiral razor wire, which meets the higher anti-climb and anti-damage requirements of high-security prisons.
