We were quoted €15/m for 2m high chicken wire type fencing.  This included erecting but putting our own posts in.  Don' t know how far apart the posts should be though.

Quote was from Ebre Metal on the Ravel de Crist to Roquetes road.

You can buy all the fencing kit at Mayors but I don't know how much it is yet.  Still looking.

Hi Pondgirl  - thanks for your reply - we will go to Mayors when we're next down.
Hi Angela and John - what we are looking for are the metal posts (piquetes?) and then the galvanized fencing (not panels) - a bit like chicken wire but not in squares - more in lines if that makes sense - you see it all round fincas around Tortosa. 
We found a good guide on how to install the fencing on the Leroy Merlin site but no reference to them selling the posts or the wire fencing.
Thanks for your help
Haze and Alan

Well, Pondboy , that is possible on the basis that Hazeaandalan is going to build a skirt wall under the fence to give yourself a level face to work from but if they were gonna erect a fence straight from the ground as it seems they are, then that approach will not work. What ever they do they will need  properly supported corner posts (usually achieved by angled sections in each direction to "brace" the main upright, two or three main running wires will be spanned between the braced main uprights. These will need tensioning (hence the supported main uprights)- to much tension and you run the risk of pulling supports over during winter time (shrinkage) and the opposite if your span wires are to slack. You will fix you diamond mesh or what-ever fence you buy to that. Just find a fence that looks like what you want and see what they have done. Not exactly rocket science!!

Good luck....
