Product Overview

Concertina Razor Barbed Wire (Galvanized Steel/Stainless Steel) including BTO-10, BTO-12, BTO-18, BTO-22, BTO-28, BTO-30, CBT-65, CBT-60 is designed for high-security applications such as prisons and border security.

Razor Barbed Wire

Razor wire, also known as concertina wire or barbed tape, consists of sharp razor blades and high-tensile steel wire. It serves as a passive safety product with extremely high security, often installed atop fences or walls to form impassable barriers.

  • High Security: Economical and effective perimeter barrier against illegal invasion.
  • Corrosion Resistance: Hot-dip galvanized or stainless steel materials for harsh environments.
  • Durable: High-strength core wire resistant to standard cutting tools.
  • Deterrent: Rigid and sharp blades provide a strong psychological and physical deterrent.
  • Quick Deployment: Can be set up rapidly for temporary or permanent security.

Frequently Asked Questions
What is the main difference between BTO and CBT razor wire?
BTO (Barbed Tape Obstacle) typically features shorter blades, while CBT (Concertina Barbed Tape) features longer, more aggressive blades like the fish-hook style, providing higher security levels.
How do I choose the right zinc coating for my project?
For standard environments, normal hot-dip galvanizing (40g/m²) is sufficient. For coastal or high-humidity areas, we recommend high-zinc coating (200-300g/m²) or stainless steel for maximum corrosion resistance.
What is the difference between single coil and cross-type concertina wire?
Single coils run in a simple spiral. Cross-type (concertina) uses clips to join adjacent loops, creating a diamond-shaped mesh when expanded, which is much harder to penetrate.
Is the core wire easy to cut?
No, we use high-tensile steel wire as the core. It is designed to be extremely difficult to cut with standard hand tools, ensuring the integrity of the security barrier.
Can the specifications be customized?
Yes, coil diameters, blade types, and material combinations can be customized based on specific security requirements and environmental conditions.
How is razor wire typically packaged for export?
It is usually wrapped in moisture-proof kraft paper and then enclosed in a woven bag to protect the sharp edges and prevent corrosion during sea freight.
