About Steel

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

Cast Iron

Easy-to-Machine Gray Cast Iron Round Tubes

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

Oversized Easy-to-Machine
Gray Cast Iron Rods and Discs

An oversized diameter allows for finishing to your exact requirements.

Easy-to-Machine Gray Cast Iron Sheets and Bars

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, and bushings.

Easy-to-Machine Impact-Resistant
Ductile Cast Iron Bars

Easier to machine without cracking than other impact-resistant ductile cast iron bars, these cast iron bars contain a high amount of ferrite. Use them to make cylinder and die blocks, rotary tables, and rail spacers.

Easy-to-Machine Impact-Resistant
Ductile Cast Iron Rods

With a high amount of ferrite, these cast iron rods are easier to machine without cracking than other impact-resistant ductile cast iron rods. Use them to create bushings, gears, pulleys, and pistons.

Impact-Resistant Ductile Cast Iron Rods and Discs

Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking.

Impact-Resistant Ductile Cast Iron Bars

Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking.

High-Strength Impact-Resistant
Ductile Cast Iron Rods

Containing more pearlite and less ferrite, these cast iron rods are stronger and harder than standard ductile cast iron.

Galvanized Iron and Steel Slip-On Framing and Fittings

Galvanized Iron and Steel
Slip-On Framing and Fittings

To provide corrosion resistance in wet environments, this framing is galvanized.

Easy-to-Print PLA 3D Printer Filaments

The most commonly used 3D printing material, these PLA filaments make detailed parts at a low melting point, so they won’t warp as they cool, rarely clog nozzles, and don’t require a heated printer bed.
