Razor wire is galvanized steel tape punched into blades and clinched onto a spring steel core. We make it straight, flat-wrapped and coiled, in every common blade.
| Form | What it is |
|---|---|
| Single coil (spiral) | One helix of razor tape on its core, stretched along the run and held at a set pitch by clips. The standard wall-top coil in Indian tenders. |
| Cross type | Adjacent loops clipped to each other at points round the circumference, so the coil opens into a criss-crossed barrier that is harder to push through. |
| Flat wrap | Loops flattened into a panel that lies close to a wall or fence face — neat where a round coil would overhang. |
| Straight razor tape (RBT) | Razor barbed tape on a core, run straight between posts — the horizontal lines in a Y-angle fence. |
| Double coil | A smaller coil inside a larger one, for a deeper obstacle on open ground. |
| Blade | Barb length | Barb spacing | Tape | Where it fits |
|---|---|---|---|---|
| BTO-10 | 10–12 mm | 26 mm | 0.5 mm | Short barb — dense, neat, for wall tops in towns |
| BTO-22 | 22 mm | 34 mm | 0.5 mm | Medium barb — the usual choice for Indian boundary walls |
| BTO-30 | 30 mm | 34 mm | 0.5 mm | Long barb — a harder obstacle for fence lines |
| CBT-60 | 60 mm | 96 mm | 0.6 mm | Long, hooked barb — perimeters and high security |
| CBT-65 | 65 mm | 100 mm | 0.6 mm | Longest barb — defence and prison-grade perimeters |
One straight line of 0.52 mm razor tape on a 2.5 mm core weighs about 82 g per metre — roughly 12.2 m per kg. In a coil, multiply by the length of tape: a 600 mm coil of 50 turns holds about 94 m, about 7.7 kg.
Razor wire cuts and snags; barbed wire deters. See concertina vs barbed wire.

About 82 g per metre for a straight line of 0.52 mm tape on a 2.5 mm core. A coil weighs that much per metre of tape in it.
Concertina is razor wire formed into a coil. Straight razor wire is used as the horizontal lines of a fence, or on its own.
