Iranian cable trays are available in metal (galvanized steel) and PVC types, with various sizes, coatings, and configurations to suit industrial, commercial, and residential applications.

Metal Cable Trays

Material and Coating: Iranian metal cable trays are typically made from galvanized steel, including ST37 steel, with coatings applied either by hot-dip galvanization (60–70 microns, highly resistant to moisture and corrosion) or cold galvanization (10–20 microns, suitable for dry environments) . Dimensions:

• Thickness: 0.5 mm to 3 mm
• Width: 50 mm to 1100 mm
• Length: 2 m to 3 m
• Edges and height are designed according to cable load and number of cables . Types and Configurations:
• Perforated trays: Allow ventilation and heat dissipation
• Ladder trays: Suitable for heavy-duty industrial cables
• Solid-bottom trays: Protect cables from dust and debris
• Accessories: Include elbows, tees, connectors, wall supports, roof supports, and conversion pieces . Applications: Metal trays are preferred in industrial, acidic, wet, or humid environments due to their durability and fire resistance .

PVC Cable Trays

Material and Features: PVC trays are non-combustible, self-extinguishing, and resistant to acids, chemicals, UV rays, and rodents. They have smooth corners to prevent cable damage and are conductive-safe if cables are damaged . Sizes: Available in multiple sizes, such as 60×150 mm and 60×200 mm, with lockable doors for easy access and maintenance . Advantages:

• Long lifespan in humid or chemical environments
• Lightweight and corrosion-resistant
• Suitable for areas where metal trays may corrode quickly .

Selection Considerations

When choosing an Iranian cable tray, consider:

• Cable load and number of cables
• Environmental conditions (humidity, chemical exposure)
• Coating type (hot-dip for high moisture, cold for dry areas)
• Support systems and installation method
• Fire safety requirements (metal trays are preferred in high-risk areas) . Iranian manufacturers provide a wide range of customizable trays to meet specific project requirements, ensuring safety, organization, and long-term durability in electrical installations .
