About Aluminum

Compare over 20 aluminum alloys to find the right material for you—all with material certificates for traceability.

Square Tubing

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.

Aluminum Bolt-Together Framing and Fittings

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

Flat and Angled Bolt-Together Framing and Fittings

Telescoping Weld-Together Rails

Create posts of varying lengths.

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 Levels

Mount these bull's eye levels to workstation and table frames made of T-slotted framing for easy leveling in all directions on the horizontal plane.

T-Slotted Framing Structural Brackets

Connect T‐slotted rails and reinforce joints for structural stability.

T-Slotted Framing Mounting Brackets

Attach sensors, tubes, and other components to T-slotted framing rails and structures.

T-Slotted Framing Linear
Bearings and Track Rollers

Mount components to these load-rated bearings and track rollers to add linear motion along T-slotted rails.

T-Slotted Framing Pivots

Pivots provide smooth motion at the junction between two T-slotted rails.

T-Slotted Framing Storage Components

Stay organized with hooks, bin boxes, shelves, and tool holders that work with T-slotted framing.

T-Slotted Framing Panels and Doors

Add panels to T-slotted framing to create machine guards and strip doors.

T-Slotted Framing Bases

Get projects off to a quick start with these kits that include the components you need to build simple structures, such as workbenches, workstations, and stands.

T-Slotted Framing Caps, Covers, and Seals

Seal T-slots, rail ends, and gaps between rails to keep out dust, debris, and other contaminants.

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.

T-Slotted Framing Slides, Tracks, and Rollers

Slide drawers, panels, and doors with these tracks and rollers.

T-Slotted Framing Hinges

Use hinges to add doors, lids, and machine guards to T-slotted framing.

T-Slotted Framing Locks and Latches

Secure doors and windows made of T-slotted framing to protect valuables or restrict access for safety.

T-Slotted Framing Manifolds

Distribute compressed air, hydraulic fluid, or water from a single supply to multiple locations.

T-Slotted Framing Conveyors

Add rollers to T-slotted framing to create flow rails, ball transfer tables, and other manual conveyors.

T-Slotted Framing Mounts for
Monitors and Computer Accessories

Attach and position phones, tablets, monitors, and computer accessories on T-slotted rails.

T-Slotted Framing Positioning Arms

Make your T-slotted framing workstation more ergonomic. These positioning arms let you move tools and other items within reach, reducing fatigue and streamlining repetitive processes.

T-Slotted Framing Handles

Add a convenient grip to steer carts or open and close doors, windows, and drawers made of T-slotted framing.

T-Slotted Framing Jigs

Align and drill accurate holes in T-slotted rails with these reusable templates.

T-Slotted Framing Lighting

Illuminate workstations, enclosures, and machines.

T-Slotted Framing Outlet Strips

Add electrical outlets to workstations with these outlet strips that mount on T-slotted rails.

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.

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.

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.

High-Profile Strut Channel

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

Corner Strut Channel Brackets

Surface Strut Channel Brackets

Push-In Strut Channel Brackets

Push these brackets into strut channel and tighten the included cam screws for a partially concealed connection.

Strut Channel Nuts

Serrated grooves grip the lip of the channel.

Strut Channel Nuts with Hollow Studs

Run wires through the hollow stud of these nuts or use them as vents.

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.

Strut Channel Washers

Use with hex nuts to connect threaded rod.

Strut Channel Covers

Create a four-sided raceway for cable, or give a more finished look to strut channel structures.

Heavy Duty Locking-Slotted Framing and Fittings

Build structures that stand up to more vibration and movement than T-slotted framing but with the same versatility and installation ease. Instead of T-shaped slots, these rails have slots that turn up and inward to keep connections rigidly aligned together.

Miniature T-Slotted Framing and Fittings

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

Robot Bases

Elevate robot arms with these bases so they can reach onto raised surfaces, such as conveyor belts or workstations.

Surface-Mount Stroboscopes
with Certificate of Calibration

Integrate these stroboscopes into fast-moving lines to check quality.
