14. What Is the Difference Between Aluminum Cable Tray and Steel Cable Tray?

Aluminum cable trays have many advantages over steel trays.

Aluminum has a high strength to weight ratio as compared to steel, which means that if we were to compare two cable trays of similar strength which are also of the same length, width, and height, the Aluminum tray will not only support the heavier load but also weigh only 60% as much as steel tray.

Similarly, the corrosion resistance power of Aluminum is far better than steel, which makes Aluminum tray more practical to use.

The aluminum tray is also easier to install than the steel trays.

However, an Aluminum cable tray is a little bit expensive as compared to a steel tray.

15. What Is the Difference Between Steel Cable Tray and Stainless-Steel Cable Tray?

The advantage of a steel cable tray over stainless steel cable tray is its low cost.

However, stainless steel has higher concentrations of Cadmium and Nickel and a lower concentration of carbon, and these relative concentrations make stainless steel highly corrosion resistant.

Thus, the cable trays made from stainless steel can withstand even extreme conditions.

17. What Is Rung Spacing in Cable Ladder?

The interval of space between which rungs are attached to the side rails is known as rung spacing.

Different types of cable ladders are characterized by different rung spacing.

Rung spacing is measured from the centerline of one rung to the centerline of the next rung.

The most common rung spacing for the rung cable ladder or ladder cable tray is 9 inches, supporting all types of cables.

18. What Is a Galvanized Cable Ladder?

A cable ladder is usually galvanized to make it suitable for long term use as well as make it resistant to corrosion, rust as well as organic and inorganic chemicals such as acids or bases.

A ladder can be galvanized in a number of ways.

It can either be made from pre-galvanized sheets, or it can be hot-dip galvanized after its construction.

Other methods are powder galvanization, epoxy resin finish, and special paints.

A galvanized cable ladder not only works better, but it has a greater life span.

It is also able to withstand harsh conditions.

19. What Is the Price of a Cable Ladder?

Just like with cable trays, the price of the cable ladder depends upon its base material from which it is constructed, its design, as well as its specifications.

A galvanized cable ladder is expensive than a non-galvanized cable ladder.

Also, the prices of cable ladders vary in different regions of the world.

20. What Is the Difference Between Cable Tray and Tray Ladder?

A cable tray is a relatively simpler structure consisting of a single sheet of metal or metal alloy.

The cable ladder, on the other hand, consists of evenly spaced rungs attached to two parallel rails on both sides.

Cable trays are typically manufactured with a length of 3 meters. Cable ladders are manufactured with a length of 3-6 meters.

The cable tray is itself made perforated or with slot patterns to make it easier to tie cables to it.

On the other hand, only rungs in cable ladders are perforated or come with slot patterns.

Cable trays are more suitable for lightweight cables, equipment, and tubing.

On the other hand, the cable ladder efficiently supports heavy cables, equipment, and tubing.

As the cable tray is covered at the bottom, it not only reduces the electromagnetic interference but also prevents the cables from drooping while enabling maximum ventilation.

However, in the case of cable ladders, the cables on them are exposed to the environment and aren’t safe against electromagnetic interference.

Additional covers have to be added to prevent interference and UV effects.

However, in a cable ladder, due to its ladder structure, airflow is maximum that prevents the overheating of cables fastened to it.
