These three weight measurements are how scrap yards calculate what you’re paid. Gross weight is the total weight of your vehicle (or container) including the scrap. Tare weight is the weight of your vehicle after the scrap is unloaded — the empty weight. Net weight is the difference: gross minus tare equals the weight of your scrap, which is what you’re paid for. At endless metals in Auckland, our drive-through weighbridge captures both weights automatically. If you’re bringing scrap in a trailer or ute, you drive onto the weighbridge on arrival (gross), unload, then drive back across (tare). The net weight is calculated instantly and your payment is based on that figure multiplied by the price per kilogram for your specific grade.
