When most people think of security fencing, chances are they imagine them with razor coils. Razor coils are certainly an effective barrier (although, like any type of fencing, they're not completely infallible.) But since razor coils are so rare in Canada, many people don't know too much about them aside from that. So we've put togehter some interesting facts about razor coils so you can take a "crash course."
Razor coils can be very dangerous to people and animals. Which is why you can't just install them wherever you like in Canada. You will need to get special permission to install razor coils in Canada, and it's quite difficult to get. Razor coils are mostly used on correctional facilities and military sites, with government permission, and in very remote locations. Even then, they are positioned very high up, or on the inside of other kinds of fencing, so there's very little chance anyone would accidentally come into contact with them. Don't try to install razor coils until you have permission! You might get a fine.
Razor coils are used all over the world, and although we mostly use what is called "BTC" in Canada, there are other kinds. Razor coil types include:
BTC or Barbed Tape Concertina, which is the round razor coils we seem most often in Canada. They're made of interconnected spirals of razor wire, which gives them the "concertina" shape they're named for.
Flatwrap which is a two dimensional razor coil. The razor wire is wound to create a spiral and then clipped where the wires intersect, but unlike BTC, this is not a three dimensional coil. Which allows it to be tied directly onto fence mesh.
Electrocoils are a type of BTC coils that have electric fence insulators and wire inside the actual coil. Thes can be connected to a fence energiser, so you not only have razor coils, but an electric current inside the coil. These are used on high security prisons in some parts of the world, where there are zoned electric fences that are monitored from a central command station or guardhouse.
Razor mesh is not exactly a coil, but it's made of the same material. Razor mesh is supplied in large sheets of diamond mesh made from razor wire.
Most of these types of razor mesh are not available and not commonly used in Canada, but it's worth knowing that they exist.
You might think that razor coils are only available in galvanized steel, and that's the most common material in Canada. But razor coils are also made in materials like stainless steel, in grades 304 and 316, and sometimes, a stainless steel barb strip is wrapped around a galvanized wire core.
In most cases, you will see Canadian razor wire specifications calling for "galv/galv" which means a galvanized razor strip wound around a galvanized core wire.
Razor coils come in different sizes, and because of their shape, that is usually measured based on the diameter of the coil. The most common sizes for razor coils are 450mm or 18", 700mm or 28", and 980mm or 39". The diameter of the coil is also based on the amount it is stretched. So of course, if the coil is stretched more or less, the diameter will change.

Many kinds of fencing can be installed as a DIY project - but never razor coils! Razor coils should only ever be installed by highly trained fence professionals, using the right tools and PPE.
The last thing we're sharing about razor coils today is that they are also very hazardous to dispose of. Whether you have leftover coils on your site or you're taking down and replacing old coils, they need to be disposed of with the utmost care. Razor coils can be very dangerous and even deadly to people and animals, and they should never be disposed of in an ordinary landfill. Make sure that the coils are taken off site carefully, cut into pieces and disposed of at a metal recycling facility that is capable of disposing of them properly.
