TRUECORE

TRUECORE is a brand of steel products marketed for structural framing in residential and light commercial construction. Developed and manufactured by BlueScope Steel, TRUECORE encompasses cold-formed high-strength steel sections used for wall frames, roof trusses, purlins, and floor framing. The steel is produced with protective coatings intended to improve corrosion resistance and durability, enabling longer service life in a range of climates. The exact coating systems vary by market but typically include zinc-aluminium or galvanised coatings designed to work with appropriate fasteners.

TRUECORE steel is designed to be strong, straight, and lightweight compared with timber framing and some other metals, supporting prefabrication and faster installation. It is typically used with compatible connectors and fasteners and is intended to meet local building codes and standards for structural framing. Suppliers provide technical data sheets, installation guidelines, and warranties to ensure consistent performance.

Markets and usage: The product is widely marketed in Australia and New Zealand and is used in new residential construction, extensions, and some commercial projects. It is chosen for its dimensional stability, resistance to warping, and suitability for prefabrication, though installation requires trained crews and appropriate fasteners and coatings, especially in coastal or high-humidity environments.
