The Short Answer

For truly high-security perimeters — prisons, military sites, power substations, border crossings — razor wire (concertina wire) is the right choice. For farms, rural boundaries, and low-risk industrial sites, barbed wire is sufficient and cheaper. Many projects use both: a 358 or chain-link fence body topped with razor wire coils.

Razor Wire (Concertina Wire)

Razor wire is made from a central high-tensile steel core wire with sharp steel blades crimped along its length, typically supplied as concertina coils (e.g., 450 mm, 600 mm, or 980 mm diameter).

Advantages:

• Extremely effective deterrent — very difficult and dangerous to cross
• High-tensile core resists cutting
• Fast to install on top of existing fences or walls
• Available in galvanized or stainless steel for corrosive environments

Common uses: prisons, airports, substations, oil & gas plants, embassies, border fences.

Barbed Wire

Barbed wire uses two twisted steel wires with sharp barbs spaced at intervals. Lighter, cheaper, easier to handle.

Advantages:

• Lowest cost perimeter option
• Simple installation with T-posts or wooden posts
• Adequate for livestock control and marking boundaries

Common uses: farms, ranches, rural land boundaries, low-security industrial yards.

Installation Tip: Tension Wire Through the Coils

For razor wire mounted on cranked fence arms, professional installers run a tension wire through the concertina coils and fix it to each arm — not loose binding wire wrapped around the brackets. A tensioned wire keeps the coils evenly spaced, prevents sagging in wind, and gives the installation a clean, professional finish that clients notice.

What to Ask Your Supplier

• Blade profile and core wire tensile strength
• Coil diameter, loop count, and clips per roll
• Galvanized vs stainless steel (stainless for marine/coastal sites)
• Whether coils are factory-clipped (faster install) or loose
