Barbed wire or razor wire?
Barbed wire is the economical choice for farms and long boundaries. Razor wire gives a much higher climb delay and is specified for prisons, military and critical infrastructure.
Security wire products
Barbed Wire & Razor Wire
Security wire divides into two families. Barbed wire is the traditional twisted two-strand wire with four-point barbs, still the most economical topping for farms and long boundaries. Razor wire presses sharp blades around a high-tensile core and is supplied as concertina coils, flat wrap sheets or welded mesh where a much higher climb delay is required.
›Barbed wire: core #12–#15½ BWG, 4-point barbs
›Barb spacing: 3″ / 4″ / 5″ / 6″
›Razor blade types: BTO-10/12/22/30, CBT-60/65
›Concertina coil diameter: 450–1,000 mm
›Surface: hot-dip galvanized 100–505 g/m², or PVC coated
›Forms: coils, flat wrap sheets, welded razor mesh, line wire
Also known as: Barb wire · Four-point barbed wire · Concertina wire · Razor tape wire
Two Wire Families
Barbed wire covers economical topping and boundary work; razor wire is specified wherever climbing must be stopped. Both are galvanized for outdoor service and can be combined on one fence line.
Barbed Wire (Four-Point)
The economical topping for farms, ranch boundary and general security fences.
Also known as: Barb wire · Four-point barbed wire · Twisted barbed wire
Two zinc-coated strands twisted together with four-point barbs at regular spacing. It is the standard topping above field fence, chain link and panel fences, and the first choice wherever long lengths of deterrent wire are needed at low cost.

Frequently Asked Questions
How is razor wire installed?
Concertina coils clip onto Y-arms or brackets along the fence top; flat wrap sheets fix directly to walls; welded razor mesh is bolted like a panel. Clips and tie wire are supplied with the order.
What do BTO and CBT mean?
BTO is barbed tape obstacle (BTO-22 is the standard blade type); CBT is concertina barbed tape. Both describe the blade profile of the tape.
