About Steel

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

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.

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.

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.

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 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.

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.

Zinc-Galvanized Low-Carbon Steel Rods

These rods are zinc galvanized for good corrosion resistance.

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.

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-Round Bars

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

Wear-Resistant AR400 Carbon Steel

The nickel and molybdenum content gives AR400 carbon steel the ability to resist wear better than all other carbon steel. It's often used as wear strips, liners, and deflector plates.

Ultra-Strength Carbon Steel (UHSS) Sheets

This UHSS (ultra 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-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.

Impact-Resistant A516 Carbon Steel

Even in low temperatures, A516 carbon steel resists breaking upon impact. Also known as pressure-vessel-quality (PVQ) steel, it is mostly used for boilers, storage tanks, and pressure vessels.
