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 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 I-Beams

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

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.

Architectural 6063 Aluminum H-Bars

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Strut Channel

Extra Low-Profile Strut Channel

Run cable and tubing in the tightest spaces with channel that is one-quarter the height and one-half the width of regular strut channel.

Side-to-Side Stacked Strut Channel

This welded, one-piece strut channel combines two strut channels side-to-side.

Back-to-Back Stacked Strut Channel

This welded, one-piece strut channel combines two strut channels back-to-back.

Strut Channel with Closed Ends

With welded ends, these short lengths of strut channel provide a finished look when mounting clamps and accessories to machines and surfaces.

Low-Profile Strut Channel

Half the height and the same width as regular strut channel, this low-profile strut channel fits into tight spots and is compatible with many of the same brackets.

Curved Strut Channel

Create continuous runs of channel without corners.

High-Profile Strut Channel

Up to two times the height of regular strut channel, this high-profile channel is stronger than regular strut channel.

Strut Channel for Quick-Connect Clamps

For compatibility with quick-connect clamps to secure pipe and conduit without screws and tools, this strut channel has narrow slotted holes.

Telescoping Strut Channel

Slide the strut channel into the tube for telescoping length adjustments.

Flat and L-Shaped Bolt-Together Framing and Fittings

Steel Hat Channel

In addition to creating space inside walls or ceilings—to prevent dampness or make room for insulation—these channels can also be used to level or resurface them.

Mounting Channels for Enclosures

Customize component placement without drilling leaky holes—these channels screw into the mounting bosses in your enclosure.
