Do you want trouble stopped at the wall, or at your door? Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Concertina: large coils, strong deterrent. - Flat wrap: lower profile, neat appearance. - Blade type sets the barb shape and length. Quick answer Razor wire comes as concertina coils, which expand into large spiral rolls along a wall top, or flat wrap, which lies in flat overlapping loops for a lower profile. It's specified by blade type (for example BTO-22), coil diameter (such as 450 mm or larger) and material, usually galvanized steel for outdoor durability.
