Structural steel tubing is exactly what it sounds like: hollow steel sections made to support heavy loads. They come in square, rectangular, and sometimes round shapes. These tubes are measured by their width, height, and wall thickness, and they’re made from steel grades that meet strict industry standards, including ASTM A500.

These tubes are versatile. Whether you’re building frames, supports, or enclosures, they provide consistent strength and performance. Choosing the right structural tubing is about reliability and precision — and that’s what Brown Strauss delivers.

Our structural grade steel tubing application list is long because this product fits a wide range of projects. You’ll find it in:

• Commercial and residential construction, for frames and supports
• Bridges and infrastructure projects
• Industrial equipment, machinery frames, and safety cages
• Agricultural structures and heavy machinery support

The strength, straightness, and uniformity of our tubing help projects run smoothly. It holds up against heavy loads and resists deformation, which makes it a solid choice for critical structural work.
