The Stainless Steel Behind the Tray Matters

“Stainless steel” is not one single material. Different grades have different chemical compositions and levels of corrosion resistance.

Depending on the application, SS cable trays may be manufactured using grades such as:

• SS 304
• SS 316
• Other stainless-steel grades specified for the project

SS 304

Often considered for general industrial and commercial environments where good corrosion resistance is required.

SS 316

Contains molybdenum and generally offers improved resistance to chloride-containing environments compared with SS 304, making it a potential choice for more demanding applications.

The correct grade should always be selected according to the actual environment rather than assuming SS 316 is required for every project.

A Cable Tray Designed Around Cleanliness

One of the less obvious advantages of stainless steel is its suitability for installations where maintaining a clean and easily maintainable surface matters.

SS Cable Trays can therefore be considered for:

• Pharmaceutical facilities
• Food-processing plants
• Chemical industries
• Laboratories
• Clean manufacturing areas
• Water-treatment facilities
• Coastal installations
• Process industries

The tray design, surface finish and installation method should still be selected according to the hygiene and environmental requirements of the facility.

Why Stainless Steel Can Be the Right Material

• Corrosion Resistance

Suitable stainless-steel grades provide strong resistance to many common forms of atmospheric corrosion.

• No Conventional Paint System Required

The corrosion resistance comes primarily from the stainless steel itself, rather than depending on a conventional external paint coating.

• Suitable for Moist Locations

SS trays can be considered where persistent humidity, water exposure or wash-down conditions make material selection important.

• Long Service Potential

With suitable grade selection and installation, stainless steel can provide a durable cable-support structure.

• Easy Surface Maintenance

A properly finished stainless-steel surface can be relatively easy to clean and maintain.

Perforated SS Cable Trays

A Perforated Stainless Steel Cable Tray contains openings in its base and/or side sections.

These openings can provide convenient points for:

• Cable fastening
• Mounting
• Ventilation
• Jointing
• Support attachment

They can be useful where cables need to be secured at regular intervals or where the installation requires a combination of cable support and airflow.

SS Ladder Cable Trays

Where larger power cables or substantial cable routes are involved, an SS Ladder Cable Tray can be considered.

Its open construction provides:

• High visibility
• Good ventilation
• Convenient cable placement
• Accessible maintenance
• Suitable mechanical support when correctly designed

The required side-rail profile, rung configuration and support span should be established from the expected cable loading.

SS Cable Tray Is Not Just for Corrosive Areas

Although corrosion resistance is a major reason for choosing stainless steel, it can also be useful where the installation requires:

Durability + Cleanability + Appearance + Long-Term Material Stability

This can make SS trays suitable for certain high-specification indoor installations as well as outdoor or corrosive environments.

Where SS Cable Trays Are Commonly Considered

• Pharmaceutical Manufacturing

Stainless steel can be useful where cleanable surfaces and resistance to process-related conditions are important.

• Food & Beverage Plants

SS cable-support systems can be considered in areas where regular cleaning and moisture exposure are part of the operating environment.

• Chemical Processing

The correct stainless-steel grade may offer better resistance to particular atmospheric or chemical conditions.

• Coastal Projects

Salt-laden air can accelerate corrosion of ordinary steel. Suitable stainless-steel grades can therefore be considered for coastal environments.

• Water Treatment Facilities

Moisture is an everyday part of many water-treatment environments, making corrosion resistance an important selection factor.

• Industrial Clean Rooms

Where cleanliness and surface maintenance are important, stainless-steel cable management can be advantageous.

SS 304 vs SS 316 Cable Tray

Factor	SS 304	SS 316
General Corrosion Resistance	Good	Very Good
Chloride Resistance	Moderate	Better
Typical Cost	Comparatively lower	Comparatively higher
General Industrial Use	Common option	Used for more demanding environments
Coastal/Marine Exposure	Application dependent	Often considered
Chemical Environment	Depends on chemicals	Depends on chemicals

Neither grade should be selected solely on the basis of cost. The chemical environment, chloride exposure, temperature and cleaning conditions should be evaluated.

How to Decide the Required Tray Size

The tray width should be based on the actual cable arrangement.

Before ordering, consider:

• Number of cables
• Cable outside diameters
• Total cable weight
• Cable grouping
• Required clearance
• Future expansion
• Support spacing
• Installation direction

A tray with additional width may be useful when future cable additions are expected, but unnecessarily oversized trays can increase project cost and space requirements.

SS Cable Tray Load Capacity

There is no single load rating applicable to every stainless-steel cable tray.

Load performance depends on:

• Stainless-steel grade
• Material thickness
• Tray width
• Side-rail geometry
• Tray profile
• Support spacing
• Cable arrangement
• Joint design

For engineering applications, the manufacturer’s load/span information should be used for the selected configuration.

SS Cable Tray Accessories

Sohum Industrial Sales Corporation can cater to requirements for accessories needed to complete an SS cable-management route.

These may include:

• Horizontal bends
• Vertical bends
• Tee sections
• Cross sections
• Reducers
• Couplers
• End plates
• Covers
• Support brackets
• Hangers
• Clamps
• Fasteners

Accessories should be selected in compatible materials and dimensions to maintain the integrity of the complete system.

Surface Finish Options

The appearance and cleanability of stainless steel can also be influenced by its surface finish.

Depending on the application, customers may specify:

• Standard mill finish
• Brushed finish
• Smooth finish
• Project-specific finish

For hygiene-sensitive installations, the required surface finish should be agreed with the project and process requirements.

SS Cable Tray Installation Considerations

Good material selection can be undermined by poor installation.

During installation, attention should be given to:

• Correct support spacing
• Proper jointing
• Compatible fasteners
• Cable weight
• Cable securing
• Thermal movement where applicable
• Electrical bonding/earthing requirements
• Avoidance of sharp edges
• Proper alignment
• Adequate space for inspection

For cables with special bending or separation requirements, the installation should follow the cable manufacturer’s recommendations.

Stainless Steel and Earthing

Stainless steel is electrically conductive, but the presence of a metallic tray does not by itself guarantee compliance with the site’s protective-earthing requirements.

The complete installation should be designed to address:

• Electrical continuity
• Bonding across joints
• Protective earthing
• Connections to the site’s earthing network

The exact requirements depend on the electrical system and applicable standards.
