Grading is the process of classifying scrap metal by its purity, condition, and composition. Each metal type has multiple grades — for example, copper ranges from Copper #1 (Bright & Shiny), which is clean and uncoated, down to Domestic Copper, which contains fittings and contaminants. The grade directly determines the price: cleaner metal with fewer impurities fetches a higher rate. At endless metals in Auckland, our team grades your material on arrival using industry-standard classifications. Understanding your grades before you arrive helps you sort effectively and maximise your return. See our live pricing page for current rates by grade.
