Cable trays in the Philippines

A cable tray is a structural system that supports and routes electrical cables for power distribution, control, and communication. Cable trays serve as an alternative to open wiring or conduit systems. They are frequently used for cable management in commercial and industrial construction. They are particularly useful when changes to a wiring system are expected as the new cables can be easily installed by laying them on the tray.

If you’re wondering where to find cable trays in the Philippines or want to know more about its uses, and the different types of materials and finishes, read more below.

Types of Cable Trays in the Philippines

There are several different types of cable trays. Stanhope Prime Resources currently offers the following cable trays in the Philippines.

• Wireway

• Ladder Type

• Wire Mesh Tray

• Perforated Tray

  
  

Wireway Cable Tray

Solid wireway cable trays are covered completely and are typically used for running wiring. As the system is enclosed, it does not provide access to the wiring or cabling. It also requires that the cables are covered.

Ladder Cable Trays

Ladder cable trays feature two side rails connected by rungs. This design allows easy access to the wires and cables on the tray and also serves as an anchor for tying down cables. Ladder cable trays provide maximum ventilation and are suitable for long spans.

Wire Mesh Cable Trays

Wire mesh cable trays are made by welding stainless steel wires together to form a basket-like mesh. They are mainly used for telecommunications, low voltage, and fiber optic cables because of their light structure. The design also provides for maximum ventilation.

Perforated Cable Trays

Perforated cable trays have a ventilated bottom with side rails. This design offers more cable support compared to ladder cable trays. They are commonly used with instrumental and power cables.

Finishes for Cable Trays in the Philippines

Cable trays from Stanhope come with various finishes:

• Hot-dip galvanized

• Powder coated

• Aluminum

• GI bare

• Stainless Hairline/2B

• Epoxy painted

  
  

Hot-Dip Galvanized Finish

Hot-dip galvanizing is a process of coating iron or steel with a layer of zinc to protect against corrosion. The metal is immersed in a bath of molten zinc at a high temperature, which creates a metallurgical bond between the zinc and the base metal. The result is a robust coating that is an integral part of the steel.

Hot-dip galvanized cable trays have better corrosion protection and last longer, even in harsh conditions.

At Stanhope, our cable trays come in various renditions, such as the following:

• Solid bottom

• Perforated with round holes

• Sold with rungs

• Perforated with slotted holes

  
  

Powder-Coated Finish

Powder-coated cable trays are made from steel that has undergone a powder-coating process to create a protective and visually appealing layer. It involves spraying a dry, free-flowing powder onto the cable tray, which is cured under heat to create a durable, even coating.

The result is an anti-corrosive, fire-resistant, and moisture-proof cable tray.

Aluminum Finish

Cable trays with an aluminum finish are often made of aluminum alloy, making them lighter than steel cable trays and easier to install. Aluminum is corrosion-resistant, offering durability in various environments.

Cable trays with aluminum finish have good strength and large-carrying capacity. They also have good corrosion resistance, making them suitable for high-corrosion environments—like power and chemical plants.

GI Bare Finish

Cable trays with a GI (galvanized iron) bare finish use galvanized iron without additional coating. While they are steel-coated with zinc to protect against corrosion, they are not painted or powder-coated. The cable tray retains the appearance of the zinc coating.

Stainless Hairline/2B Finish

Cable trays with a stainless hairline or 2B finish are made of stainless steel. Their surface has been treated in such a way that it provides a smooth or brushed look. The stainless hairline or 2B finish enhances the cable tray’s aesthetic appeal and corrosion resistance.

Epoxy-Painted Finish

Cable trays with epoxy-painted finish are made of steel and then coated with epoxy paint for added protection and durability. Before assembly, the steel is coated with a hybrid epoxy-polyester resin or epoxy powder. They are then de-greased and undergo amorphous phosphating by treatment tunnel spraying before the electrostatic application of the resin, which improves corrosion protection.

Epoxy paint-finished cable trays suit humid, mild chemical, and urban environments.

Connectors and Bolts Used to Install Cable Trays in the Philippines

Installing cable trays requires various connectors and bolts, such as the following:

• Cable tray connectors: used to connect additional cable trays to extend the system

• Galvanized self-drilling cover screw (6x13): used to secure the covers of cable trays

• Galvanized hexagonal bolt (5/16 x 1/2" with hex nut and double washers): used to fix cable trays to walls, ceilings, or floors

• GI nuts and GI washers: primarily used in assembly to connect sections of cable tray
