From the heart of Hamilton’s industrial landscape, Latham Steel stands as a trusted manufacturer and supplier, providing robust solutions for New Zealand’s toughest projects. We specialise in EN 9 sheet and plate, a high-carbon steel known for its exceptional durability and strength. Our commitment lies in delivering material that meets the precise demands of local industry, ensuring reliability from our yard directly to your worksite, backed by deep technical knowledge and a focus on building lasting partnerships.
This high-carbon steel is defined by its composition, primarily iron with a significant carbon content that gives it notable hardness. Through careful heat treatment, it develops impressive mechanical properties, achieving a high tensile strength and excellent wear resistance. This process allows it to be hardened to a degree that makes it far more durable than milder steels, though it retains a degree of machinability in its annealed state, offering a versatile balance for fabrication.
