Hi Meredith,

       These are hardened steel blocks. They will have a significantly lower 
permeability than mild steel. I first tried using annealed high carbon steel - 
called gauge plate - you can buy it in a wide range of sizes, but I reverted 
to mild steel.

       We can get hold of the 2" x 1/4" mild steel strip through outlets 
serving the building trade - it is used for reinforcing / joining wood beams and 
also for load bearing lintels. Hinges for farm gates are bent from this. 

       Regards,

       Chris
