Located in the heart of Hamilton’s industrial landscape, Latham Steel has built a strong reputation as a reliable manufacturer and supplier of high-quality steel products. We take particular pride in our expertise with ASTM A500 tubing, a cornerstone of modern structural design. Our commitment to local industry means we provide Hamilton and the wider New Zealand market with dependable, ready-access to this essential material, supporting everything from major commercial builds to innovative local projects with robust, homegrown steel solutions.
Our ASTM A500 tubing is a cold-formed welded carbon steel tube, primarily composed of steel with carefully controlled levels of carbon, manganese, and other elements to ensure consistent performance. This specific composition gives the tubing its excellent mechanical properties, including high strength and good ductility. It’s these characteristics—like its formidable yield and tensile strength—that make it a preferred choice for structural supports, capable of handling significant loads while maintaining its integrity.

The versatility of this tubing is truly remarkable, making it a common sight in our built environment. You’ll find it forming the sturdy skeletons of commercial buildings, shopping centres, and agricultural sheds, providing the essential framework that holds everything up. Beyond large structures, it’s also widely used for constructing industrial racks, handrails, and a variety of supportive frames in machinery. Its clean, rectangular or round profiles are not only strong but also allow for neat, architecturally pleasing designs, proving that practical strength and good aesthetics can go hand-in-hand.
