Steel

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.

Low-Carbon Steel Round Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit.

Ultra-Strength Carbon Steel (AHSS) Round Tubes

The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.

Easy-to-Weld 4130 Alloy Steel Round Tubes

Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames.

Easy-to-Weld 4130 Alloy Steel Rectangular Tubes

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.

Weld-Together Framing and Fittings

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

Telescoping Weld-Together Rails

Create posts of varying lengths.
