1. How do I calculate how many kilos of cable wire I need for a chainwire fence?
The Australian Standards state that a chainwire fence requires a cable wire every 1200mm maximum including the top and bottom cable. Cable wires are not required if there is a pipe rail. Where cable wires are required, the formula is as follows (length of fence x the amount of cable wires needed x 2 x 0.08 = kg). This is due to the cable wires are doubled then twisted together.

2. How do I calculate how many kilos of tie wire I need for a chainwire fence?
For a railless design chainwire fence, it is normally at 5kg per every 100 metres. For a railed chainwire fence, it is normally 10kg per every 100 metres.
