rebar mesh offcut (Hampton Magna CV35)

I'm looking for an offcut from a sheet of rebar mesh (the stuff used to reinforce concrete floors)
It needs to measure approx 1metre x 1.5 metres, and ideally would be made from 6mm or 7mm bar.

Has anyone got any lying around - maybe left over from a concreting project? [I want it for a non-standard purpose, but rebar mesh would be ideal for my purpose.]

I can collect within a reasonable distance of Warwick.

Many thanks,
Roger Mills
