Light gauge steel is thin sheet steel typically under 3mm thick, sourced from items like roofing iron, ductwork, filing cabinets, shelving, and tin cans. It is one of the most common types of scrap brought to Auckland yards by homeowners and tradespeople. Light gauge steel is lower in value than heavy structural plate because it contains less metal per cubic metre and may include coatings like galvanising or paint. At endless metals, we distinguish between clean light gauge (uncontaminated sheet) and dirty light gauge (mixed with plastic, wood, or other attachments). Removing non-metal attachments before drop-off will improve your grade.
