American Made and Manufactured with Sustainable EAF Steel
Steel HSS, Pipe & Tube
Hollow Structural Sections (HSS) are steel tubes known for their high strength, efficiency and versatility. As the industry expands, so do Nucor’s structural steel tube capabilities and the range of industries we proudly serve.
We provide a variety of high-quality hollow structural sections (HSS) and steel tube products in various shapes (round, square or rectangular), all of which are melted and manufactured in the United States.

Versatility
Due to its durability and high strength-to-weight ratio, steel tubing is structurally efficient and can meet the toughest requirements for tolerances and consistency.

Sustainability
Nucor is the only vertically integrated producer of EAF domestic steel sheet and HSS, resulting in sustainable, low-embodied carbon steel products.

Transparency
Our powerful customer partnerships are built on transparent practices, including clear communication and industry-leading environmental product declarations (EPDs).

Pipe Piling
Treatments & Finishes
Alternate Weld Placement
The weld seam is positioned on a different face (typically the shorter side) to meet structural or fabrication needs, including improved appearance or load distribution.
Band Saw Cutting
The bundle is cut to precise lengths using a band saw, providing clean end preparation for tight tolerances to reduce fabrication time on-site.
Destructive Testing
Sample sections are physically tested to failure to assess material properties such as strength and weld performance, validating compliance with specifications.
Flash Removal
The internal weld bead is mechanically removed to create a smooth inner surface, improving fit for connections and flow-through applications.
Flux Leakage Testing
A non-destructive test that uses magnetic fields to detect surface or near-surface defects to detect leakage and ensure product integrity and quality.
Re-Metalizing
A zinc coating is applied to protect the steel from corrosion, extending service life in outdoor or harsh environments.
Special Tolerances
HSS is produced with tighter dimensional tolerances than standard, which helps ensure exact fit and performance in precision applications.
Stenciling
Product information is printed directly onto the steel product, improving traceability and inventory management during handling and construction.
Surface Critical
The HSS is manufactured with enhanced surface quality for aesthetic or coating-critical applications, such as exposed architecture or finishing processes.
