About Steel

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

Low-Carbon Steel Sheets and Bars

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 fixture clamps and mounting plates.

Tight-Tolerance Low-Carbon Steel Bars

Sometimes called flat stock, these bars have a thickness and width that are precision ground to a tight tolerance.

Zinc-Galvanized Low-Carbon Steel Sheets and Bars

These sheets and bars are zinc galvanized for good corrosion resistance.

Low-Carbon Steel Bars with Rounded Edges

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.

Nickel-Coated Low-Carbon Steel Bars

In addition to good corrosion resistance, the nickel coating provides better wear resistance than the zinc-galvanized coating.

High-Temperature Aluminized
Low-Carbon Steel Sheets

Coated with an aluminum-silicon alloy, these sheets resist corrosion while withstanding long-term exposure to high temperatures. Use in drying ovens, furnaces, and smokestacks.

Mold- and Mildew-Resistant
Low-Carbon Steel Sheets

A silver-filled resin coating on one side of these sheets protects from degradation caused by bacteria and fungi.

Paintable Galvannealed Low-Carbon Steel Sheets

The galvannealed coating allows these steel sheets to be painted without prepping the surface. They're easier to weld and more scratch resistant than zinc-galvanized steel sheets. Use them for outdoor signs, cabinets, and doors.

Low-Carbon Steel Rods and Discs

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles.

Tight-Tolerance Low-Carbon Steel Rods

These rods are precision ground and held to a strict straightness tolerance, so they're ready for turning in a lathe.

Zinc-Galvanized Low-Carbon Steel Rods

These rods are zinc galvanized for good corrosion resistance.

Chrome-Plated Low-Carbon Steel Rods

The matte plating on these rods increases corrosion resistance and wear resistance.

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.

Low-Carbon Steel 90° Angles

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 edge protectors.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Low-Carbon Steel U-Channels

Also known as mild steel, low-carbon steel is easy to machine, form, and weld.

Zinc-Galvanized Low-Carbon Steel U-Channels

These U-channels are zinc galvanized for good corrosion resistance.

Low-Carbon Steel Hex Bars

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's often fabricated into low-strength fasteners and fixture clamps.

Low-Carbon Steel T-Bars

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 Balls

Also known as mild steel, low-carbon steel balls are our easiest steel balls to machine. They are often used for parts that don’t require high strength, such as knobs.

Low-Carbon Steel Triangles

Weld these steel triangles to strengthen joints in structural applications.

Zinc-Galvanized Steel Wire

This wire is zinc galvanized for good corrosion resistance. It will stay in place when bent, so it’s commonly used for bundling and as tag wire.

Low-Carbon Steel Wire

Also known as black-annealed wire.

PVC-Coated Steel Wire

Coated with PVC for corrosion resistance, this carbon steel wire will stand up to outdoor use.

Low-Carbon Steel Half-Round Bars

A ready-to-use alternative to cutting a rod in half.

Easy-to-Machine Low-Carbon Steel

Sulfur is added to these sheets, which helps them produce smaller chips than other low-carbon steel sheets when they’re machined. Smaller chips mean less clogging and more coolant flow while you cut.
