Suspended Support (L Profile) – Product Description

The Suspended Support with L Profile (also known as angle bar or angle iron support) is a versatile and economical overhead mounting solution designed for suspending lightweight to medium-duty cable trays, small cable ladders, conduits, and other electrical or mechanical components from ceilings, overhead structures, or concrete slabs. The simple L-shaped (90-degree angle) cross-section offers a practical balance of strength, simplicity, and cost-effectiveness.

The L profile features two perpendicular legs of equal or unequal dimensions, providing inherent rigidity and resistance to bending in multiple directions. This simple yet effective geometry makes it easy to fabricate, cut, drill, and assemble on-site without specialized tools or equipment. The flat surfaces of both legs provide convenient mounting areas for threaded rods, hangers, brackets, and tray attachment hardware.

Key advantages of the L profile for suspended support applications:

• Cost-effective: Lower material cost compared to U-channel or I-beam profiles

• Lightweight: Easy to handle, transport, and install, reducing labor and shipping costs

• Easy modification: Can be cut, drilled, or welded on-site using common tools

• Versatile mounting: Either leg can serve as the horizontal support surface, offering flexibility in system design

• Space-efficient: Minimal vertical height requirement for installations with limited overhead clearance

Typical configurations:

The L profile can be oriented in several ways depending on the application:

• One leg vertical, one leg horizontal (standard orientation) – The horizontal leg supports the cable tray directly or carries mounting brackets, while the vertical leg provides bending resistance and connects to threaded rods

• Inverted orientation (horizontal leg on top) – Useful when the tray needs to sit below the support level or when accommodating other services above the tray

• Back-to-back configuration – Two L profiles bolted or welded together to form a T-shaped or modified channel for increased load capacity

Suspended support system assembly:

The L profile serves as the horizontal trave rse or continuous stringer, suspended by threaded rods anchored to the overhead structure. The rods attach to the L profile through pre-drilled holes or by using beam clamps and angle brackets. The cable tray is then secured to the horizontal leg of the L profile using bolts, saddle clamps, or tray support brackets. The open design allows for easy leveling and height adjustment during installation.

Typical applications:

• Suspending lightweight cable trays and small ladder trays in commercial buildings

• Overhead support for electrical conduits and communication cables

• Light industrial facilities (assembly lines, workshops, warehouses)

• Mechanical and electrical (M&E) rooms

• Parking garages and tunnels with light to medium cable loads

• Temporary or retrofit installations where quick, low-cost support is needed

Material and finish options:

Manufactured from high-quality steel or aluminum, available in:

• Pre-galvanized steel – Standard indoor applications

• Hot-dip galvanized steel – Enhanced corrosion protection for damp or outdoor environments

• Stainless steel (304 or 316) – For corrosive, marine, or hygienic environments

• Aluminum – For lightweight, non-corrosive, or aesthetic applications

• Primed/painted – For color-matched or specialty indoor applications

Available dimensions:

Standard L profile sizes range from small sections (e.g., 20×20×3mm) for very light loads to larger sections (e.g., 50×50×6mm or 75×75×8mm) for medium-duty applications. Equal-leg and unequal-leg configurations are available. Custom lengths, hole punching patterns, and pre-assembled support kits can be provided upon request.

Installation considerations:

While the L profile offers excellent value for light to medium loads, it is important to note that for long spans, heavy cable bundles, or high-vibration environments, U-profile or I-profile supports may be more appropriate due to their higher moments of inertia and torsional rigidity.

For projects where simplicity, economy, and ease of installation are priorities, the L profile suspended support delivers reliable performance at the lowest total installed cost.
