Low-Carbon Steel Rectangular Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways. To increase their wear resistance, you can surface harden them with heat treating. These tubes are manufactured to ASTM or EN standards for quality and performance.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

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. To increase their wear resistance, you can harden them with heat treating. These tubes have been manufactured to SAE and military standards for quality and performance.

Weld-Together Framing and Fittings
Create strong structures by welding this framing together. Add metal panels to close off openings. Slide the rail into the fitting and weld in place.

Telescoping Weld-Together Rails
Create posts of varying lengths. To telescope rails, slide one length of rail into the next larger size rail (for example, a 1 3/4" height rail fits into a 2" height rail and a 3/4" dia. rail fits into a 1" dia. rail). Weld the rails together at the desired length to create strong structures. These rails are not compatible with weld-together framing and fittings.
Carbon steel rails are lightly oiled.
Galvanized carbon steel rails have good corrosion resistance in wet environments and can be used outdoors.
