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 Rods

These rods are zinc galvanized for good corrosion resistance.

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 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 I-Beams

Made of rigid low-carbon steel, these I-beams are often used in construction, framing, lifting, and hoisting applications.

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.

Grid Fixture Plates

Precision ground to the tightest parallel tolerance, these steel plates have threaded and unthreaded holes in a grid pattern to support precise positioning and repeatability when machining.
