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
