I am trying to learn where the Moritz Steel Company was located. It was thriving in the 1940's?

I do have a partial address. It is 6515,Juniata Ave. There is no indication of what city. The ariel photo I have shows another large factory in the background with several stacks, and a large body of water. All the cars in my photo appear to be late 1940's. Thanks for any info!!
