Best Industries FZE, Fabrication & Installation of structures and cable containments in Aluminium, Steel and Stainless Steel.

Steel

Steel cable trays are fabricated from continuous roll-formed structural quality steel. With roll-forming steel, the mechanical properties are increasingly allowing the use of a lighter gauge steel to carry the required load. This reduces the dead ports and the installers. The corrosion resistance of steel varies widely with coating and alloy.

 

Advantages:

• Electric Shielding

• Finish Options

• Low Thermal Expansion

• Limited Deflection

 

Aluminum

Aluminum’s excellent corrosion resistance is due to its ability to form an aluminum oxide film that when scratched or cut reforms the original protective film. Aluminum has excellent resistance to “weathering” in most outdoor applications. Aluminum cable tray has excellent resistance in many chemical environments. Typically, aluminum cable tray can perform indefinitely, with little or no degradation over time, making it ideal for many chemical and marine environments.

Advantages:

• Corrosion Resistance

• Easy field Fabrication & Installation

• Excellent Strength-to-Weight Ratio

• Excellent Grounding Conductor

 

Stainless steel

Stainless steel cable trays are fabricated from continuous roll formed AISI type 304 or AISI type 316/316l stainless steel. Both are non magnetic and belong to the group called austenitic stainless steels. Like carbon steel, they exhibit increased strength when cold worked roll-forming or bending.

Several important conditions could make the use of stainless steel imperative. These include long term maintenance costs, corrosion resistance, appearance and locations where product contamination is undesirable. Stainless steel exhibits stable structural properties such as yield strength and high creep strength at elevated temperatures.

Stainless steel cable trays are welded using stainless steel welding wire to ensure each element exhibits the same corrosion resistant characteristics as the base metal. A detailed study of the corrosive environment is recommended when considering a stainless steel design.

Advantages:

• Superior Corrosion Resistance

• Withstands High Temperatures
