Razor barbed wire, also known as razor barbed wire, is a barrier made of hot-dip galvanized steel plate or stainless steel sheet punched into a sharp blade shape, and high-tension galvanized steel wire or stainless steel wire as the core wire. Because the barbed wire has a unique shape and is not easy to touch, it can achieve excellent protection and isolation effects. Razor barbed wire guardrail is a new type of protective net, which is formed by cross-welding of blade-shaped straight barbed wire. It is mainly used for confinement protection of garden apartments, government units, prisons, outposts, border defense, etc.; it can also be used for anti-theft windows, high-speed guardrails, and isolation fences.
