here in OKC we have always had the same pricing on steel at all our scrap yards no matter if its heavy I-beam or a steel storage shed u tore down,,always one price , this monday it was down to .02 a pound,,i have never padded my loads,, they always inspect,at the scale, and take pics of load and u and vehicle too..once as i was unloading i saw a 20# propane tank 10 feet away, and went to look at it, it looked nearly new,,well it was intact,and still had fuel in it !!! so i put it in back of my truck,,one guy there at unloading spot, didnt know if he saw or not,,went to payout,told the lady about it, that some idiot left it there, its like a bomb,if they crush it ,,she agreed and i left with it..every once in a while is see something like that and take it home,thick steel plate,round bar,I-beam,large angle iron,short pieces mind u , nothing over 2 ft, and they have never said anything,,cant do that if u cheat all the time,,now i do save AL pull tabs off steel soup can lids and put 10 or so in a beer can then stomp it flat,, but its AL just like the can,,u cant show up at a scrap yard with a 5 gallon bucket full of AL pull tabs and expect them to take it, so in a AL can they go,,also save the steel can lids, put them in a large baked beans can, about a dozen or so, insert another steel can into that,as far as it will go , then smash the top of the 2 cans flat,and its all contained in the large steel can, and all steel..
