Unfit for commercial use.
I bought two of these and put them immediately into production. The "blue steel" is of very low quality and I would not buy another. These pans rust easily and must be seasoned with oil after each use to prevent corrosion. Even if meticulously washed and oiled, they still leave a noticeable discoloration on the bread. I must use them for now, but for the price, I expected much better quality. They have no brand name on them, and they are quite cheaply made. Anyone with access to a sheet metal shop could do just as well. I will be discarding them as scrap metal as soon as I can afford a Matfer Exopan.
