Concertina Coils along with horizontal Razor Wire provides the ultimate security and safety for your property. When criminals see a fence topped with razor wire, they’ll think twice about trying to get into your property. Concertina Coil over boundary wall makes the perimeter virtually unclimbable, as a result, people will move on to easier targets when they see your concertina fencing installed.
Now we will give you a brief description for erecting Concertina Razor Wire. Before that, our most important advice will be-be very careful! Concertina wire can cause severe injuries if you’re not careful and needs to be handled very safely.
Quantity Estimation :
Before proceeding to the installation, you should first estimate the total length of the razor wire needed to cover the entire area of the fence that you want to equip. To get the total length of the wire you need the following measurements :
a) Linear wire length (LWL) which is the total length of wire placed horizontally above your fence. These are usually composed of Five wires placed on parallel lines with at least 100 mm distance from each other. To compute the total wire length for this, use the following formula:
- Linear wire length = Fence perimeter length x 5 rows .
b) Helical wire length (HWL) which is the total length of the concertina wire placed on the linear Razor Use this only if you chose to install the said coiling wires for added security.
Compute for the wire length as follows :
- Helical wire length = Total fence perimeter Length ÷ average stretch length per coil.
As a result, the total wire length needed in your installation will be equal to the combined length of the LWL and HWL. Don’t forget to use METRE in all wire measurements.
Horizontal Razor Wires are to be installed first. To do this, take one end of your razor wire and attach it securely to a corner post brace. Stretch your wire on a straight line and tie it to each brace until the entire perimeter is covered. Do this two more times in order to complete the three-parallel-wire installation.
After this, install the Concertina wires by tying each coil onto the installed parallel wires. Make sure that each coil runs from the bottom to the topmost parallel wire. Do this until the entire perimeter is covered. Cut the razor wire on ends if needed.
For erection, a team of three to five would be advisable to handle this job. While installing your Concertina wire, don’t forget to ensure your safety and the safety of those people working with you. Proper tools, protective gear, and secured ladders should be used.
