Uses Of Sheet Metal Cable Tray

Metal cable trays are indeed quite useful in several ways not excluding;

  • Sheet metal cable trays offer support to insulated power/communication/control cables.
  • They’re used in commercial and industrial applications for communication and control in the management of cables.
  • A sheet metal cable tray also comes in handy in situations that require frequent changes in installations.

Their open design facilitates the expansion, reconfiguration, upgrading, and relocation of networks.

  • A sheet metal cable tray allows for an appropriate routing path for underground cables as well as overhead cables.
  • Additionally, sheet metal cable trays are designed to be open thus facilitating heat dissipation as well as efficient inspection.
Types Of Sheet Metal Cable Tray

Sheet metal cable trays come in three main categories;

Solid Bottom Cable Tray

This sheet metal cable tray protects very sensitive circuits.

Also, it offers shielding in cases where holes and breaks lack in the completed installation.

solid bottom cable tray

solid bottom cable tray

The main reason why solid bottom cable trays are mostly preferred is that they offer protection from electromagnetic interference.

They are mostly preferred when installing fiber optic cables since drooping cables might affect the performance of the system.

Ladder Cable Trays

Ladder cable trays are the most common in the installation of a cable wiring system.

Not only can we attribute this to free airflow across the cables but also these types of cable trays prevent moisture from accumulating.

As the name implies, this cable is lined with stainless steel wire mesh which supports and routes cables with a small diameter.

Oftentimes, wire mesh cable trays are used for telecommunication, low voltage, and fiber optic cables which are supported on short spans.

Features Of Sheet Metal Cable Tray

Some of the main features of sheet metal cable trays include;

  • The presence of holes helps in the easier installation of cables and provides proper ventilation.
  • The rib located at the base of perforated sheet metal help in promoting load resistance.
  • Most if not all sheet metal cable trays have surface finish options that enhance the quality of the product.
  • Sheet metal cable trays allow the addition of cables to an existing system.
Sheet Metal Cable Tray Vs. Wireways

The main difference between a wireway and a sheet metal cable tray is that a cable tray is not a raceway while a wireway is.

Choosing Material For Sheet Metal Cable Trays

When selecting the type of materials, you’d want to factor in the following properties;

  • Corrosion
  • Thermal contraction and expansion
  • Installation consideration and electrical grounding capacity.

That said, here are some of the major types of materials used for sheet metal cable trays;

I. Steel – Continuous roll-formed structural steel is what’s used in the fabrication of steel cable trays.

II. Galvanized Steel – Zinc is used in the fabrication of galvanized steel cable trays.

III. Stainless Steel – Similar to steel, stainless steel is fabricated from continuous roll-formed steel (specifically AISI Type 304 or AISI Type 316/316L stainless steel).

IV. Aluminum – Structural grade “copper-free” aluminum extrusions are used to fabricate aluminum cable trays.

Advantages Of Sheet Metal Cable Tray

Sheet metal cable trays are made from different metals including Aluminum, steel, or stainless steel.

Some of the benefits of sheet metal cable trays are not limited to;

  •  Offering a safe and open solution for cables and wire routing.
  • Sheet metal cable trays made from galvanized or stainless steel are not only aesthetically pleasing but also provide a perfect solution to cable management.
  • Sheet metal cable trays with galvanized coating often have great resistance to abrasion, and corrosion and are easy to install.
  • Aluminum sheet metal cable trays have a great strength-to-weight ratio.
  • Stainless steel sheet metal cable trays can withstand high temperatures.
  • Sheet metal cable trays are highly durable.

Materials such as steel and aluminum are known for their strength and durability and therefore they produce durable products.

  • Sheet metal cable trays are also available in several heights, lengths, and widths.

You have options when it comes to selecting the one that best suits your preferences.

  • You can either get them in light-duty or heavy-duty. Additionally, every system is incorporated with time-saving fixings and fittings.

These fixtures and fittings are ideal for industrial, retail, and offshore environments installations.

Why Choose Perforated Sheet Metal Cable Tray

Perforated sheet metal cable trays have holes at the bottom to create adequate ventilation and position for the cable lines.

The holes also facilitate proper drainage of water.

In addition to that, they also allow for fast heat dispersion and easier entry and exit of cables from any point.

This in turn makes the installation processes easier, flexible, and faster.

Also, a perforated sheet metal cable tray is easier to maintain and clean.

Using a perforated sheet metal cable tray provides stronger support for wire cables as compared to the common welded wire mesh cable trays.

Be sure to carefully understand the features of different types of perforated sheet metal trays prior to purchasing.

This will assist you in determining which one is best for your specific needs.

For example, galvanized steel perforated cable trays can either be ideal for indoor or outdoor use.

The electro-galvanized cable tray is suitable for indoor uses while the hot-dipped galvanized steel is ideal for outdoor cable protection.

Sizing Sheet Metal Cable Tray

To determine the size of a sheet metal cable tray, there are certain factors that you need to consider;

  • The type of metal of the tray
  • The cable mixture
  • Whether the trays have a solid bottom or are perforated
  • The number of single conductors

The size of sheet metal cable trays is often given in mm squared or inches squared.

To determine the size of a cable tray, you need to multiply the width and the loading depth.

The size of the cable tray is accurate when it’s 50% full of wire or cable.

Below are some calculations to help you determine the size of a sheet metal cable tray;

Area of cable trays= Width of cable tray x Height of cable tray

Width of cable tray = No. of cable layers x No of cable tray run x Cable width

Depth of cable tray = No. of layers of cable x Maximum cable diameter

Sheet Metal Cable Tray Standard

Sheet metal cable tray standards are categorized into performance standards, manufacturing standards, and test standards.

Some of the sheet metal tray standards are not limited to;

  • NECA NEIS 105 – For metal cable tray system installation.

Ways Of Mounting Sheet Metal Cable Tray

You can either choose to mount your sheet metal cable trays onto a wall or suspend it from a ceiling.

Either way, your wires and cables will be routed in a building in a manner that makes them easily maintainable.

Here are some steps to laying cables on a wall-mounted cable tray;

  1. Use a pre-fabricated flange or GI channel to fix the cable tray support. The measurements, size, and intervals of the support should match the standards, the number of cables, size, and specifications of the cable.
  2. Install the cable tray as illustrated in the diagram below;
  3. Lay the cable as you maintain the distance from the calculation.
  4. Use a cable tie to tie the cable and afterward label them as required.

Some of the support types for wall mounts are not limited to;

  • Wall and cantilever support brackets
  • Underfloor and toproof support
  • Vertical support

You might want to consider the following types of support when suspending a sheet metal cable tray from the ceiling;

  • Hanger rod clamps support
  • Center hung support
  • Overhead hangers
  • Trapeze support
Sheet Metal Cable Tray Vs Raceways

Sheet metal cable trays are different from raceways in that raceways completely enfold the cable inside it.

They enclose both metallic and non-metallic materials that support cables and wires.

On the other hand, a sheet metal cable tray supports cables used for communication, power distribution, and control.

Sheet metal cable trays are mostly a suitable alternative to open wiring and are commonly used for the management of cables in industrial and commercial construction.
