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

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.

Tight-Tolerance Low-Carbon Steel Bars

With a thickness that's precision ground to a tight tolerance, these bars are sometimes called flat stock.

Zinc-Galvanized Low-Carbon Steel Sheets and Bars

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

Nickel-Coated Low-Carbon Steel Bars

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

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.

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.

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 parts that don’t require high strength.

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 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.

Low-Carbon Steel Hex 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 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.

Zinc-Galvanized Low-Carbon Steel 90° Angles

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

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 Wire

Also known as black-annealed wire.

Zinc-Galvanized Steel Wire

This wire is zinc galvanized for good corrosion resistance.

PVC-Coated Steel Wire

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

Low-Carbon Steel Balls

Also known as mild steel, use these low-carbon steel balls in parts that don't require high strength.

Low-Carbon Steel U-Channels

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 Half-Rounds

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 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 Half-Ovals

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.

Steel Perforated Sheets

Use thesee sheets for machine guards and protective panels in noncorrosive environments.

High-Flow Steel Perforated Sheets

Hexagonal holes provide a large open area for high-flow applications.

Metal Panels

Close off openings in structures while allowing air to pass through.
