About Steel

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

Multipurpose Low-Carbon Steel

Zinc-Galvanized Low-Carbon Steel Sheets and Bars

These sheets and bars are zinc galvanized for good corrosion resistance.

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.

Zinc-Galvanized Low-Carbon Steel Rods

These rods are zinc galvanized for good corrosion resistance.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Zinc-Galvanized Low-Carbon Steel U-Channels

These U-channels are zinc galvanized for good corrosion resistance.

Zinc-Galvanized Steel Wire

This wire is zinc galvanized for good corrosion resistance. It will stay in place when bent, so it’s commonly used for bundling and as tag wire.

Weld-Together Framing and Fittings

Metal Panels

Close off openings in structures while allowing air to pass through.

Telescoping Weld-Together Rails

Create posts of varying lengths.

Bolt-Together Framing and Fittings

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 Angled Bolt-Together Framing and Fittings

Strut Channel Framing and Fittings

Strut Channel

Strut Channel with Mounting Plate

Back-to-Back Stacked Strut
Channel with Mounting Plate

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.

Back-to-Back Stacked Strut Channel

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

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.

Surface Strut Channel Brackets

Corner Strut Channel Brackets

Offset-Surface Strut Channel Brackets

Wraparound Strut Channel Brackets

Designed to wrap around the sides of strut channel, these brackets provide a stronger hold than other strut channel brackets.

Strut Channel Brackets for Quick-Connect Clamps

These brackets have narrow slots compatible with quick-connect clamps for securing pipe and conduit on the channel side of struts without screws or tools.

Strut Channel Nuts

Serrated grooves grip the lip of the channel.

Strut Channel Nuts with Springs

A spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.

Sit-on-Top Strut Channel Washers

Add hardware to strut channel without having to hold the washer in place or reach inside the channel.

Strut Channel Washers

Use with hex nuts to connect threaded rod.

No-Spin Strut Channel Washers

Notches on these washers grip the channel to keep them in place.

Centering Strut Channel Washers

Keep hardware centered in the strut channel slot.

Strut Channel Shelf Brackets

A tab on the end of these shelf brackets fits inside the strut channel for extra stability.

Strut Channel Braces

Support the corners of strut channel structures.

Strut Channel Pivots

Position two strut channels at a 30° to 90° angle, then tighten the bolt to secure.

Springs

Compression Spring Stock

Use these steel springs in noncorrosive environments.

Extension Springs with Special Ends

For specialty applications and connections, these springs have unique end types.

Extension Springs with Hook Ends

Use these steel springs in noncorrosive environments.

Control of Liquids, Gases, and Solids

Easy-to-Form PVC-Coated
Galvanized Steel Wire Cloth

Build screens, barriers, and enclosures that last—the PVC coating on this wire cloth provides excellent corrosion and wear resistance for a long service life.

Easy-to-Form Galvanized Steel Wire Cloth

The welded joints keep opening sizes uniform and prevent fraying as you bend this wire cloth.

Galvanized Steel Wire Cloth

This wire cloth is woven and available in the widest variety of sizes we offer.

Extra-Rigid Galvanized Steel Wire Cloth

Also known as space cloth, wires are crimped where they intersect to maintain an accurate opening size when used with heavy materials. The crimping process also adds strength and rigidity.

Vacuum-Rated Large-Diameter Steel Tubing

This tubing has the strength to withstand vacuum applications up to 29" Hg.

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.
