Cable tray systems have become an essential part of industries and commercial construction. They are very popular for their quick, economical, flexible alternative to messier wiring problems. The cable tray manufacturers in Dubai. produced trays from corrosion resistant material (stainless steel or steel or aluminium alloy) or with corrosion resistant finish (zinc or epoxy) to make them last for long. The commonly used finishes include galvanised, Pre-galvanised/mill-galvanised and hot dip galvanised. Depending upon the installation setup, corrosion and cost, the mechanic decide the suitable material of cable tray systems. Some of the most common materials used for producing cable tray systems are:
Aluminium cable trays
Trays made up of aluminium alloy are generally used for high strength and weight projects which require greater resistance to corrosive environments.
The advantages of using aluminium cable trays are the ease of installation and it’s lightweight. Also, aluminium cable trays are non-magnetic and electrical losses are decreased to a greater level.
Steel cable trays
Trays made up of steel are processed with forming and extrusions to increase the mechanical strength.
The advantages of Steel cable trays are it’s high strength and low maintenance cost.
Notable disadvantages of steel trays are its weight, low electrical conductivity and poor corrosion resistance ability.
Stainless steel cable trays
Cable trays made up of stainless steel offer greater strength. the advantages of stainless steel trays are its resistance to both organic chemicals and inorganic chemicals at high temperature
Finishes of cable tray systems
Cable trays are normally coated with galvanised, pre-galvanised and hot dip galvanised finishes in order to minimise the corrosion effect. The resistance to corrosion is directly related to the thickness of the coating and the environmental hardness.
