What is the scrap value of pallet racking?

The price of scrap steel underwrites the scrap value of pallet racking.  We use various sources of information to gather data on the the current market price, one valuable site http://www.letsrecycle.com/prices/metals/ferrous-metals shows the value is dropping again.  The value of used racking is also fixed to a certain extent by the cost of new and the sort of savings our customers expect when compared to the major manufacturers price.
