For over four decades, Latham Steel has been a trusted partner in Hamilton, New Zealand, providing industry with high-quality steel tubing solutions. Our dedication to precision manufacturing ensures a reliable supply of ASTM A513 tubing, a product we know is critical for your projects. We take pride in supporting the local and national engineering sector with materials that meet rigorous international standards, backed by our team’s deep expertise and a commitment to customer service that has been our hallmark since the beginning.
The makeup of ASTM A513 tubing is primarily carbon steel, chosen for its excellent balance of strength and formability. This gives the tubing impressive mechanical properties, offering good yield and tensile strength while remaining relatively easy to weld, bend, or machine to your specifications. It’s this dependable combination that makes it such a versatile choice for so many applications, providing a solid and cost-effective foundation for building everything from simple frames to complex machinery.
