Electrode palletizing and packing
All electrodes are to be palletized on to one pair of wooden stringers complete with end caps, sombreros (or end covers), brand labels and electrode tags to form the most basic of pallet formations.All the wood used for the palletizing, packaging, blocking and bracing is to be heat treated conforming to, and marked with, the ISPM No15 requirements. It applies to all wood materials with a thickness greater than 6mm. Wood based products such as plywood, particle board, orientated strand board, medium-density fiberboard, etc. are all exempt. All parts are to be stamped/branded with the internationally recognized "wheat stamp".Materials and specificationsSummary of Materials- Wooden stringers
