Before buying these items, be sure they are solid copper and not copper 
plated.  The snail strip works by chemically irritating the snails if 
they try to cross it. The rodent and bird control screen entangles and 
irritates bird's feet or rodents teeth. It is more likely to be copper 
plated steel.  For shielding these would probably be fine if they are 
solid copper and might be ok if they are plated. trying to use them to 
carry current would likely be disappointing, structural copper is 
usually not well refined and has  higher resistance.
