Razor Barbed Wire in BTO and CBT Blade Types

Blade geometry and coil diameter published in full, so you can specify the deterrent instead of guessing it.

Product Overview

What Razor Barbed Wire Is and Who Buys It

Razor barbed wire is a steel tape punched into blades and clinched around a core wire. Anwang supplies it in electro galvanized, hot dipped galvanized and stainless steel.

It can be installed as flat barbed tape wire or as a concertina coil fixed to a wall or an existing fence.

Eight blade specifications are held, from the short BTO-10 blade to the long CBT-65, with coil diameters from 450 mm to 960 mm.

Key Benefits

  • Full blade table: thickness, core wire diameter, blade length, blade width and blade spacing for all eight types.
  • Coil table gives external diameter, number of turns and the standard covering length, so you can order by metres of perimeter.
  • Single coil and cross type concertina, so both the light and the heavy specification are available.
  • Three finishes: electro galvanized, hot dipped galvanized, stainless steel.
Who It Is For

Buyers Who Specify Razor Barbed Wire

  • Prison, military and government perimeter contractors
  • Airport and port security packages
  • Substations, tank farms and other unmanned critical sites
  • Fencing contractors adding a topping to welded panel or chain link runs
  • Border and boundary works that need a rapid-deploy concertina

Problems It Solves

A fence that only demarcates does not delay anyone. A blade topping converts a boundary into a deterrent.

Blade length and spacing are what actually decide how the wire behaves - and most suppliers will not publish them.

Coil diameter and turn count control how many metres a coil covers. Buying by weight rather than covering length leads to short runs.

Galvanized blade tape corrodes at the punched edge; stainless is available where the environment demands it.

Materials

Material Options

The blade is punched from steel tape and clinched onto a 2.5 mm core wire. Electro galvanizing is the economy finish for dry inland sites. Hot dipped galvanizing carries a heavier zinc layer for exposed perimeters. Stainless steel is specified where coastal salt or chemical exposure would eat a zinc coating.

Quality Control

Blade length, blade width, blade spacing, core wire diameter and coil turn count are the dimensions that define the product; all of them are published in the tables on this page. Check the blade specification stamped on the delivery against the order - BTO-22 and BTO-28 look similar in a photograph and behave differently on a fence.

Manufacturing Process

How Razor Barbed Wire Is Made

Tape punching

Steel tape is punched to the ordered blade profile - BTO or CBT.

Core wire clinching

The punched tape is clinched around a 2.5 mm core wire.

Coiling

For concertina, the tape wire is formed to the ordered external diameter and turn count.

Clipping

Cross type coils are clipped so the concertina opens to its covering length.

Packing

Coils are compressed, tied and palletised or bagged.

Comparison

How It Compares

ProductWhere It Fits
Razor barbed wireBlade tape; high deterrence; fitted as a topping or standalone concertina
Traditional barbed wireTwisted wire with barbs; lower cost; lower deterrence
Welded mesh fenceThe structure itself; razor wire is what you add on top of it

Use Guide

  • Pick the blade first: short BTO blades for general perimeter, long CBT-60 and CBT-65 blades where deterrence has to be visible from a distance.
  • Use the coil table to convert perimeter metres into coils - a 500 mm CBT-65 single coil covers 10 m.
  • Cross type coils cover less per coil at the same diameter because they carry more turns.
  • Specify hot dipped galvanized or stainless within a few kilometres of the sea.
  • Always handle with cut-resistant gloves, and keep the coil tied until it is fixed at one end.
FAQ

Razor Barbed Wire Questions Buyers Ask

Answers taken from our own product record. Where a figure has never been published, we say so instead of guessing.

What is the difference between BTO and CBT blades?

BTO blades are 0.5 mm thick and 10-30 mm long. CBT blades are 0.6 mm thick and much longer - 60 mm on CBT-60 and 65 mm on CBT-65 - with 100 mm blade spacing.

How many metres does one coil cover?

It depends on diameter and type. A 450 mm CBT-65 single coil covers 8 m, a 500 mm covers 10 m and a 960 mm covers 13 m. Cross type coils in BTO-12, 18 or 22 cover 9-16 m depending on diameter.

What core wire do you use?

2.5 mm on every blade type listed, with the stated tolerance.

Can I get it in stainless steel?

Yes. The three listed materials are electro galvanized, hot dipped galvanized and stainless steel.

Can it be fitted to an existing wall?

Yes - it can be installed as barbed tape wire or as a concertina coil to walls or fencing.

Do you supply the fence as well as the topping?

Yes. Welded mesh fence panels and chain link fence are made in the same plant, so the perimeter and its topping ship together.
