What Is Full-Depth Strut Channel?

Full-depth 1-5/8" x 1-5/8" strut is one of the most commonly used profiles in modular framing and support systems. Compared with shallow 13/16-inch channel, the deeper section provides additional depth, greater rigidity, and more room for support hardware and framing assemblies.

Its standard dimensions make it compatible with a wide range of channel nuts, clamps, brackets, threaded-rod supports, splice fittings, post bases, and other strut-system accessories.

Full-Depth vs. Shallow Strut

1-5/8" Full-Depth Strut

Standard full-depth channel profile
Greater section depth than shallow channel
Common for mechanical, electrical, and framing systems
Provides additional mounting space for hardware
Useful where a more substantial framing member is desired

13/16" Shallow Strut

Lower-profile channel design
Useful where installation space is limited
Common for lighter support and wall-mounted applications
Reduced standoff from the mounting surface
Often selected where full-depth channel is unnecessary

Galvanized vs. Green Painted Strut

Galvanized Strut

Zinc-coated steel surface
Improved corrosion resistance compared with standard painted channel
Useful in many commercial and industrial environments
Provides a durable metallic finish
Common where moisture resistance is an important consideration

Green Painted Strut

Painted surface finish
Common for dry indoor electrical and mechanical installations
Clean, recognizable appearance
Suitable for many general-purpose applications
Typically provides less corrosion protection than galvanized channel

Slotted vs. Solid Strut Channel

Slotted Strut

Pre-punched mounting slots
Allows faster field attachment
Provides more adjustment during installation
Useful for conduit, piping, framing, and equipment support
Reduces field drilling in many applications

Solid Strut

No pre-punched slots
Provides a continuous solid channel surface
Useful where custom mounting locations are preferred
Common in fabrication and structural assemblies
May be selected where slot spacing is not desirable

Why Choose 14-Gauge Strut?

Efficient Handling

Lighter than heavier-gauge channel
Easier to move, cut, and position in the field
Useful for many general-purpose support applications
Well suited for electrical and light-to-moderate mechanical work

Versatile Framing

Supports conduit and cable-management systems
Useful for pipe and equipment support
Compatible with standard strut fittings and accessories
Allows modular field assembly and future adjustment

Common Applications

Electrical Support

Electrical conduit support
Cable and wire support
Junction-box mounting
Electrical equipment framing
Tray and raceway support
Utility and service-room installations

Mechanical & Industrial Support

Pipe support
Mechanical equipment mounting
HVAC support assemblies
Wall-mounted support frames
Ceiling-hung support systems
General industrial fabrication

Compatible Strut Hardware

1-5/8" x 1-5/8" strut channel is designed to work as part of a modular support and framing system. Compatible accessories may include:

Channel nuts and spring nuts
Pipe and conduit clamps
Angle brackets and corner fittings
Flat plates and splice fittings
Threaded rod and rod couplings
Beam clamps
Post bases and mounting feet
Equipment-support brackets
End caps and protective accessories

Confirm that all selected hardware matches the channel profile, gauge, load requirement, finish, and installation environment.

Installation Guidance

Confirm the required channel size, gauge, finish, and slot configuration before ordering.
Verify the total support load and spacing requirements for the installation.
Use compatible strut nuts, brackets, clamps, fittings, and fasteners.
Cut channel square using an appropriate saw or approved cutting method.
Deburr cut ends before handling or assembly.
Protect cut steel surfaces as required by the installation environment.
Use appropriate anchors for concrete, masonry, steel, or other mounting surfaces.
Support suspended installations with properly sized threaded rod and hardware.
Do not exceed the rated capacity of the channel, fasteners, fittings, anchors, or supporting structure.
Confirm spacing requirements for conduit, piping, cable, or equipment being supported.
Installation should comply with applicable electrical, mechanical, structural, and building-code requirements.

20-Foot Length Handling

Twenty-foot channel is useful for long continuous support runs and can reduce the number of splice fittings required compared with shorter lengths.

Because of the overall length, plan for freight, unloading, storage, transportation, and jobsite access before ordering. Use appropriate handling methods to prevent bending, twisting, or damage to the galvanized surface.

Frequently Asked Questions

What size is this strut channel?

This channel measures 1-5/8 inches wide by 1-5/8 inches deep, which is a standard full-depth strut profile.

What gauge is this strut?

This product is manufactured from 14-gauge steel.

Is this strut slotted?

Yes. The channel includes factory slots that provide flexible mounting and attachment points along the length.

What is the advantage of full-depth strut?

The 1-5/8-inch depth provides more section depth and support space than shallow 13/16-inch channel, making it useful for a broader range of electrical, mechanical, and framing applications.

What is the advantage of galvanized strut?

The galvanized finish provides improved corrosion resistance compared with standard painted steel and is useful in many commercial, industrial, and moisture-prone environments.

Is galvanized strut better than green painted strut?

It depends on the environment. Galvanized channel generally provides greater corrosion resistance, while green painted strut is commonly selected for dry indoor installations and projects where a painted finish is preferred.

How long is each piece?

Each piece is supplied as one 20-foot length.

Is this strut sold by the foot?

This product is supplied in 20-foot lengths. Order quantities should be based on the total footage required and the selling-unit configuration shown on the product page.

Can this strut be used outdoors?

Galvanized strut provides improved corrosion resistance compared with painted channel, but suitability for outdoor, wet, chemical, coastal, or highly corrosive environments depends on the exact galvanizing process and project requirements.

Can this strut support electrical conduit?

Yes. Full-depth strut channel is commonly used to support conduit, cable, raceway, boxes, and related electrical systems when properly sized and installed.

Can this strut support pipe?

Yes. It may be used with compatible pipe clamps and support hardware when the channel, fittings, anchors, and support spacing are properly selected for the load.

What hardware works with this strut?

Compatible accessories may include channel nuts, pipe clamps, conduit clamps, brackets, splice plates, threaded rod, beam clamps, post bases, and other standard 1-5/8-inch strut-system hardware.

Is 14-gauge strut suitable for every support application?

No. Load requirements vary by application. Confirm the channel load rating, span, support spacing, fittings, anchors, and supporting structure before installation.

What is the advantage of a 20-foot length?

Twenty-foot channel can reduce the number of splices required on long support runs and may improve installation efficiency on larger projects.

Is this Buy American Act compliant?

This product is represented as Buy American Act compliant. Review applicable manufacturer documentation when project-specific certification is required.

Is this strut UL certified?

UL certification information is available in the Haydon UL certification letter provided in the Product Resources section. Confirm the specific listing requirements for your project before installation.
