Based in the industrial heart of Hamilton, Latham Steel takes pride in being your trusted local source for high-strength steel. We specialise in supplying EN 10149-2 S315MC, a versatile hot-rolled sheet and plate known for its excellent balance of strength and formability. Sourced with care, this steel is perfect for New Zealand manufacturers and engineers who demand a material that can handle significant stress while still being workable for complex designs, offering a reliable solution for a wide range of demanding applications.
The S315MC grade gets its strength from a specific chemical composition that includes micro-alloying elements like niobium, vanadium, and titanium. This recipe allows it to achieve a minimum yield strength of 315 MPa after thermo-mechanical rolling, meaning it’s strong without needing extra heat treatment. It also offers good elongation, allowing it to be bent and formed without cracking, which makes it a very practical choice for fabrication.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
You’ll often find S315MC steel being put to work in situations where reducing weight without sacrificing durability is crucial. It’s commonly used for building truck chassis, trailer bodies, and various agricultural equipment. Beyond transportation, its properties make it ideal for structural components in heavy machinery, storage silos, and even some architectural applications. Essentially, it’s the go-to material when you need a component that is both lightweight and exceptionally tough.
