Square, Rectangular & Round HSS
Brown Strauss carries a full line of structural steel tubing (HSS) for construction, infrastructure, and industrial applications. With one of the largest HSS inventories in the U.S., we offer square, rectangular, and round tubing in a wide range of sizes and grades — delivered fast and ready for fabrication.
Structural steel tube, also called hollow structural sections (HSS), is used extensively in building frames, bridges, and structural supports. Available in square, rectangular, and round shapes, HSS tubing offers high strength, clean lines, and uniform performance for demanding applications.
Thanks to its enclosed shape and high strength-to-weight ratio, HSS is ideal for load-bearing columns, bracing systems, and architectural features where both performance and appearance matter.
All material meets or exceeds ASTM specifications and comes with full mill test reports. We can provide mill-direct or processed tubing based on your needs.
