Aluminum

Architectural 6063 Aluminum U-Channels

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

Anodized Architectural 6063 Aluminum U-Channels

An anodized coating on these U-channels forms a bond with the aluminum surface to improve wear and corrosion resistance.

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.

Architectural 6063 Aluminum Hat Channels

In addition to being more corrosion resistant and easier to form than multipurpose 6061 aluminum, these hat channels have flanges that make them easy to mount on flat surfaces.

Multipurpose 6061 Aluminum U-Channels

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.

Multipurpose 6061 Aluminum Z-Bars

Multipurpose 6061 Aluminum T-Bars

Multipurpose 6061 Aluminum I-Beams

Also known as American Standard I-Beams, these I-beams have rounded corners.

High-Strength 2024 Aluminum Z-Bars

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed. It offers similar performance to 7075 aluminum, but it’s not as strong.

High-Strength 2024 Aluminum T-Bars

Structural Framing

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.

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.

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 Covers

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

Strut Channel Washers

Use with hex nuts to connect threaded rod.

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 Structural Brackets

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

T-Slotted Framing Fasteners

Screw and nut sets or nuts secure brackets and other accessories to rails.

Aluminum Bolt-Together Framing and Fittings

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

Miniature T-Slotted Framing and Fittings

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

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.

Surface Guards and Trim

Metal Trim

Made of aluminum or stainless steel, this trim withstands heavy impact for maximum surface protection. It's often used on panels, boards, signs, and mirrors to protect the edges.

Panel Connecting Trim

Connect two panels while protecting the edges from damage.

Metal Wall Bases

These aluminum bases provide more impact protection than plastic bases. In addition to protecting the bottom of a wall from damage, they create a finished look where the wall meets the floor. They're commonly used in warehouse and manufacturing areas.

Metal Corner Guards

These metal guards provide more impact protection than plastic guards. Commonly used in warehouse and manufacturing areas, they protect corners on walls and other surfaces from impact.
