Stadium and rectangular Cores can be produced to specific customer requirements in a wide range of strip widths and gauges, from either Grain Orientated Silicon Steel (G.O.S.S) or Nickel Iron. Cores may be supplied either cut or uncut and with the following finishes:

• Natural (dry)

• Edge bonded, for protection from mechanical stresses.

• Fully vacuum impregnated, for greater protection from mechanical stress.

• Polypropylene covered, for electrical insulation.

• End capped, for greater electrical insulation.

• Epoxy coated, for electrical and heat insulation.

• Painted, for added corrosion protection and cosmetic purposes.

Both stadium and rectangular cores share electrical properties with toroidals but provide a solution to the mechanical constraints met by certain design applications.
