Title says it all.
Would make it a lot easier for other modders to use those items in our recipes.

Just be careful because IC2 uses the name "plateIron". I don't know if you want yours to be interchangeable with theirs.

There is no standardization between plate forms. Mine are cheap, others are expensive.

If you want to use the items, you can just pull them from the GameRegistry.

GameRegistry.findItemStack("Railcraft", "part.plate.steel", 1);
