From the heart of Hamilton, Kiri Aluminium provides industry with a material that masterfully balances strength and versatility. We are proud to be your local manufacturer and supplier of Aluminium 3003 Flat Bars, a trusted, all-purpose alloy perfectly suited for a huge range of projects. Whether your work is on a large industrial scale or a smaller custom fabrication, we deliver consistent, high-quality flat bars that form a solid and reliable foundation for building everything from durable structures to precision components.
At its core, the 3003 alloy is a blend of manganese and aluminium, a combination that significantly boosts its strength over pure aluminium without sacrificing its excellent workability. This means you get a material that is remarkably easy to cut, weld, and shape to your exact needs. It also offers very good resistance to corrosion, making it a practical and long-lasting choice for applications that might face exposure to the elements or other challenging environments.
