About Steel

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

Steel

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.

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.

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.

Multipurpose 4140 Alloy Steel Round Tubes

Made from alloy steel, also known as chrome-moly steel, these tubes resist fracturing from repeated stress. They’re used for a wide range of parts, including cylinders, rollers, and frames.

Hard Wear-Resistant 52100 Alloy Steel Tubes

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.

Structural Framing

Steel Bolt-Together Framing and Fittings

Rails are drilled with consistently spaced holes for multiple mounting options that do not require machining. Use this steel bolt-together framing to build guards, tables, and racks.

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.

Galvanized Iron and Steel
Slip-On Framing and Fittings

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

Clamp-On Framing and Fittings

Fittings come in two pieces to wrap around rails, so you can quickly modify existing structures without disassembling. Use clamp-on framing and fittings to form temporary partitions, modular conveyors, and workstations.

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.

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.
