I may be able to help with some if not all of the above. We are a AISC fabricator and have very tight controls on welding consumables. We are always discarding good SMAW rod for overexposure reasons nothing more. Examples are E7018, E8018, E9018, etc. We also have over stock of FCAW, SAW, GMAW electrodes I am always trying to get rid of.
We would have to figure out a freight agreement. Let me know some more specifics.
Best regards,
Mike Julian
