What are "cast iron style" steel radiators? Also AF Supply? Burnham slenderized?

I was browsing.
AF Supply is cheaper but out of stock. Cast iron.
Burnham slenderized is cast iron. More expensive.
Looking for 19 inch under window unit 5 feet or less. Around maybe 6,000 BTU maybe.

    You could probably find something at a salvage yard

    Thanks. Hmm. I did not think of salvage yards. I have been looking on craigslist and a local place (Bauers) that has lots of used ones. I found one that was a 4 tube under window one over 5 feet long. Too heavy for most to move. Therefore too heavy for me to ever get rid of. It was free but cost a fortune to move.

    So what is the difference between the choices I originally posted about? I realize this is a complicated area now.

    I’d get a good one from Craig’s list or your give away site.  Much cheaper than buying one and two strong guys with a cart or straps can move a radiators
     where you need it.

    I am keeping an eye on craigslist. I found one that was free. 13 in wide, 19 in high, 5 1/3 feet long. I hired two movers. They gave up at the pickup site. Too heavy. The owner cannot give it away. He is replacing with a Burnham Baseray. I will try for a smaller cast iron. Live and learn. One place has them for $10 per section. Another wants at least $30 per section.
    I found a site that explains the BTU calc for cast iron radiators, both column and tube. ???

    I found another site that does BTU requirement calculations.

    Steel CI style is a pressed steel panel radiator that looks like a cast iron rad but is a lighter version made of sheet steel.
    It is lighter and does not have the same heating properties as cast.

    Alwayus save and use working, cast iron radiators. Do not scrap them!
