I was contrasting with the days that only whole lengths could be bought. THey'd cut it in half, but you had to buy the whole length.
When steel Inc begans selling half-lengths, Federal eventually started selling half lengths also.
I bought half lengths from Federal metals before Steel inc was the thing and the Steel inc previous owner worked at federal metals. Maybe they only offered 20ft / 24ft minimum say 10 years ago. Maybe you got some other guy that was unwilling to be helpful - Steel inc guy was always a wonderful person to work with. Or maybe they had a minimum 20ft purchase but you could get larger odd amount - I remember getting 70ft. Or they had secret minimum amount you needed to spend so no one bothers them with 10ft of 3/8 rod. Or maybe my memory is starting to fail me.
I only got stuff once from Steel Inc. right after he opened up the business. Already was more then FM. Now they are even more. Him as well as new owner simply don't have the volume to compete with FM.
As for cut offs the business model is very difficult unless you go MS prices. I experienced it myself when trying to sell some steel. I talked to Steel Inc guy about it. Sure you could get a bin with scrap metal from scrap yards or even buy from some steel manufacturer at double the rate FM pays (say 200 per t). But imagine the storage, transport costs needed in addition to very low volume of sales. If someone knows FM owner he or she can ask them how much money they made from cut offs. I bet it will not be more then few 1000 per month max. This is side business at most if you have storage space.
I asked Steel inc guy about different steels - no profit there as volume too low. I asked about 1/4 lengths - again what would he do with some odd cutoffs. Imagine he offered 3" square. He might have to wait a year or more for 1/4 length to sell! Who wants space and money frozen for such a long time?
You can always compete with me on auctions - there is a lot of cut offs to be had. I mostly need square. I have few lifetime supplies of large rounds stock.
Maybe if someone had a farm or lots of land and was willing to use some of it for some scrap storage and you signed some disclaimer like on a car scrap yard this could work as side income.
