From the industrial heart of Hamilton, Latham Steel proudly provides robust and dependable materials built for New Zealand’s toughest demands. Our supply of Carbon Steel DIN 17121 Pipe is a testament to this commitment, offering a proven solution for high-pressure and structural systems. We understand that reliability is non-negotiable, which is why we ensure our pipes meet the exacting standards required for critical infrastructure and heavy-duty applications, backed by local expertise and dependable service.
This specific grade of carbon steel is formulated to deliver an excellent combination of strength and durability. Its composition is balanced to provide robust performance, while its mechanical properties are defined by a high tensile strength and good yield point, ensuring it can withstand significant internal pressure and heavy loads. This makes the material exceptionally tough and resistant to deformation, a key requirement for piping systems that must perform reliably under stress over the long term.
