Latham Steel, a trusted manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality SA 285 Grade A sheets and plates that are perfect for low- to moderate-pressure applications. This carbon steel grade is well-regarded for its excellent weldability, formability, and reliable mechanical performance, making it a great choice for non-critical pressure vessels and structural fabrication. Latham Steel guarantees uniform thickness, a smooth surface finish, and strict adherence to quality standards, ensuring that fabrication industries receive dependable materials. SA 285 Grade A plates are popular due to their affordability, ease of processing, and consistent performance in general industrial applications where moderate strength and reliability are essential.
SA 285 Grade A is a low- to intermediate-tensile carbon steel that contains controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. This material provides moderate strength, with tensile values typically on the lower end compared to high-strength pressure vessel steels. It boasts good ductility, making it easy to form and weld without sacrificing structural integrity. The steel performs consistently at ambient temperatures and offers adequate resistance in low-pressure environments. Its balanced composition and favorable mechanical properties make it ideal for applications that require straightforward fabrication and cost-effective material solutions.

SA 285 Grade A sheets and plates find their place in low- to moderate-pressure fabrication where high strength isn’t the main concern. Common applications include small storage tanks, non-critical pressure vessels, boilers, heat-transfer components, and industrial containers. They’re also utilized in general fabrication industries for ducts, structural parts, welded frames, and equipment housings. Thanks to their excellent formability, they are well-suited for components that require bending and rolling.
