For over four decades, Latham Steel has been a cornerstone of Hamilton’s industrial landscape, proudly supplying New Zealand’s toughest industries. We specialise in high carbon steel sheet and plate, materials chosen for their exceptional strength and durability. Our team understands the demanding environments our clients operate in, which is why we provide not just a product, but a reliable partnership built on local expertise and a commitment to quality that you can trust for your most critical projects.
This high carbon steel derives its robust character from a specific composition, featuring a higher concentration of carbon to deliver superior hardness and wear resistance. This results in outstanding mechanical properties, including very high tensile strength and an impressive ability to withstand significant abrasion and impact without deforming. While it is less ductile than lower-carbon steels, this trade-off is what makes it the ideal choice for applications where durability is the primary concern, standing up to punishment that would quickly degrade other materials.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
The uses for this material are as tough as the steel itself. You’ll find our high carbon sheet and plate forming the backbone of machinery that faces constant wear, such as agricultural tillage tools, mining crusher liners, and heavy-duty bulldozer blades. It’s also essential in manufacturing high-strength components like springs, durable cutting blades, and reinforced brackets for construction and logging equipment. Essentially, wherever a project demands a material that can resist heavy abrasion and maintain its integrity under extreme stress, this is the proven solution.
Latham Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products. Our extensive product range includes Pipes, Tubes, Flanges, Pipe Fittings, Forged Fittings, Sheets and Plates, catering to various industries in Hamilton, New Zealand.
