Baling is the process of compressing scrap metal into dense, compact cubes or bundles using a hydraulic baling press. This is standard practice at New Zealand scrap yards for preparing material for export shipping. Baled scrap takes up far less container space than loose material, making international transport economically viable. Different materials are baled separately — light gauge steel, aluminium cans, copper pipe — to maintain grade integrity. At endless metals in Auckland, baling is part of our yard processing operation. When you see compressed metal cubes stacked in a scrap yard, you’re looking at baled material ready for export to smelters overseas.
