Yes, both new & used.  The used ones had previously been used in the food production and storage arena.  Low cost brand new steel barrels can be extremely difficult to find nowadays.  The ones we do come across are usually ultra expensive.  So, in order to make it feasible for both our customers and us “cost wise” we seek out, and locate suppliers of used drums safe for production if we can’t get a good deal on new.  Used drums are just as good for our application.  All have a specialized FDA approved polyethylene liner they’ve been coated with on the inside that’s food grade safe.  It’s also known as “phenolic coating” or “phenolic resin”, and not to be feared.  Since drums can’t be used until this lining has been removed we always remove it before we build them.  Our method completely sanitizes them.  Used lined 55 gallon drums are totally safe.  Read more about 55 gallon barrels used for our cookers
