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.

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.

Multipurpose 6061 Aluminum Rectangular Tubes

The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

Architectural 6063 Aluminum Rectangular Tubes

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

Multipurpose 304 Stainless Steel

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications.

Polished Multipurpose 304 Stainless Steel

Polished to either a brushed or mirror-like finish, this material is often used to fabricate decorative enclosures and industrial workstations.

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Ultra-Formable 260 Brass Rectangular Tubes

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

Structural Framing

Weld-Together Framing and Fittings

Create strong structures by welding this framing together. Add metal panels to close off openings.

Telescoping Weld-Together Rails

Create posts of varying lengths.

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.

Aluminum Bolt-Together Framing and Fittings

Half the weight of steel, this aluminum framing resists corrosion in wet environments.

Flat and L-Shaped Bolt-Together Framing and Fittings

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.

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.

Strut Channel

High-Profile Strut Channel

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

Telescoping Strut Channel

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

Back-to-Back Stacked Strut Channel

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

Side-to-Side Stacked Strut Channel

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

Curved Strut Channel

Create continuous runs of channel without corners.

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.

T-Slotted Framing Rails

These rails have continuous T-slots for attaching fittings. Use this versatile framing to configure machine guards, enclosures, carts, and workstations.

T-Slotted Framing Mounting Feet and Casters

Add mounting feet and casters to T-slotted framing structures to level equipment, anchor legs to the floor, or add mobility.

Press-Fit Framing and Fittings

No need for fasteners—friction holds this framing together. Use press-fit framing and fittings to assemble carts, enclosures, and partitions.

Miniature T-Slotted Framing and Fittings

Build test fixtures, prototypes, and other small structures with this miniature version of T-slotted framing and fittings.

Mounting Channels for Enclosures

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