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.

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.

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 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 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.
