Rectangular Steel Tubings

Made from 4130 alloy steel, also known as chrome-moly steel, these tubes have low carbon content for good weldability. They’re often used for building frames and supports, since their flat sides make them easier to bolt than round tubes.

Structural Framing

Weld-Together Framing and Fittings

Create strong structures by welding this framing together. Add metal panels to close off openings.

Telescoping Weld-Together Rails
