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

Corner Brackets

Also known as angle brackets.

Corner-Reinforcing Brackets

Strengthen corners of cases and crates.

Flat-Surface Brackets

Offset-Surface Brackets

Crate-Building Brackets

Clamp these brackets to panel edges to quickly assemble crates.

Side-Hook Lift-Off Panel-Hanging Brackets

Fit brackets together to assemble truck racks, gates, crates, and fences.

Sensor and Switch Mounting Brackets

Position proximity, photoelectric, and light beam sensors and switches.

Steel Bolt-Together Framing and Fittings

Rails are drilled with consistently spaced holes for multiple mounting options that do not require machining. Use this steel bolt-together framing to build guards, tables, and racks.

Flat and L-Shaped Bolt-Together Framing and Fittings

Steel

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 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 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.

Low-Carbon Steel H-Bars

Made of stiff low-carbon steel to deflect less under load, these H-bars are commonly used in machine bases, construction, platforms, and frames.

Easy-to-Weld 4130 Alloy Steel Rectangular Tubes

4130 alloy steel has a low carbon content that provides good weldability. It's often used for structural applications.
