From the heart of Hamilton’s industrial landscape, Latham Steel has built a reputation as a trusted partner for high-strength steel solutions. We are proud to supply the robust Armour 500 sheet and plate, a product engineered to meet the most demanding challenges. This locally available material is designed for strength and longevity, offering our clients across New Zealand a reliable resource for projects where exceptional durability is not just a preference, but an absolute necessity.
The strength of Armour 500 comes from its specific composition and outstanding mechanical properties. This quenched and tempered steel achieves a minimum yield strength of 500 MPa, providing remarkable resistance to impact and abrasion. Its exceptional hardness, combined with good formability, means it can withstand punishing conditions that would quickly degrade lesser materials, making it a go-to choice for heavy-duty applications where wear and tear are primary concerns.

In practical terms, Armour 500 plate is the unsung hero in many tough environments. You’ll find it hard at work as liners in mining trucks and processing plants, as wear strips on heavy machinery, and in the construction of robust industrial bins and hoppers. Its resilience makes it ideal for protecting equipment from constant abrasion, essentially extending the life of valuable assets and reducing downtime for maintenance, which is a critical advantage in sectors like quarrying, forestry, and material handling.
