About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Low-Carbon Steel Rectangular 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.

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.

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.

Weld-Together Framing and Fittings

Telescoping Weld-Together Rails

Create posts of varying lengths.

Weld-Together Framing and Fittings

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

Hollow Linear Motion Shafts

Hollow Linear Motion Shafts with Material Certification

Keep a material certificate on hand for compliance and quality assurance needs. Certificates include a traceable lot number and material test report. These hollow shafts reduce system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

Hollow Linear Motion Shafts

Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.
