For over [number of] years, Latham Steel in Hamilton has been a cornerstone of New Zealand’s industrial landscape, proudly supplying robust materials to drive the nation’s toughest projects. We specialise in providing high-strength steels like the formidable HSC Armour Sheet Plate and the versatile 500T Grade. Known for reliability and local expertise, our team is dedicated to delivering the exceptional durability and performance that local manufacturers, miners, and builders depend on to push the boundaries of what’s possible right here in Aotearoa.
The HSC Armour Sheet Plate is engineered to withstand severe impact and abrasion, featuring a high-carbon alloy composition that prioritizes extraordinary hardness. In contrast, our 500T Grade is a high-strength, low-alloy steel that achieves a minimum yield strength of 500 MPa. This combination delivers an exceptional strength-to-weight ratio, offering not just formidable toughness but also excellent weldability and formability, making it a practical and efficient choice for a wide array of demanding structural applications.
