Compare over 50 grades of steel and cast iron to find the right material for you—all with material certificates for traceability.

Multipurpose 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.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
