   Aluminum is added to the molten steel, but it is not part of the final product. The aluminum reacts with oxygen and shields the steel during the pour. Makes a more consistent product.

   I picked up a sheet of cold rolled 20 ga steel. I found a place that sold a 4x10 sheet of CR cheaper than the 4x8 sheet of HR.
