What are the main differences between perforated and ladder cable trays?

Perforated and ladder cable trays serve different purposes in cable management:

Perforated Cable Trays: Feature a solid base with ventilation holes, providing better cable support and protection while allowing heat dissipation. Ideal for smaller diameter cables and applications requiring more protection.

Ladder Cable Trays: Have a rung-style design that offers maximum ventilation and are better for heavy power cables. They provide higher cable capacity and are easier to install in long runs.

What thickness options are available for your cable trays?

We offer cable trays in various thicknesses to suit different load requirements:

Standard Range: 1.60 mm to 2.50 mm thickness

Light Duty: 1.60 mm - Suitable for lighter cable loads

Medium Duty: 2.00 mm - Balanced strength for standard applications

Heavy Duty: 2.50 mm - Maximum strength for industrial applications

What finish options do you offer for cable trays?

We provide multiple finish options to suit different environmental conditions:

GP Sheet (Galvanized Plain): Basic corrosion protection for indoor use

Hot Dipped Galvanized: Superior corrosion resistance for outdoor and harsh environments

Powder Coated: Aesthetic finish with additional protection, available in various colors

For highly corrosive environments, we also offer stainless steel options.

What is the difference between traditional and modern earthing systems?

Traditional and modern earthing systems differ in materials, installation, and maintenance:

Traditional Earthing: Uses GI plates, strips, and wires with salt and charcoal. Requires regular maintenance and has higher soil resistance.

Modern Earthing: Utilizes gel earthing electrodes and copper-bonded rods. Maintenance-free, consistent performance, and lower earth resistance.

We recommend modern earthing for critical applications where reliability is paramount.

How do I choose between GI plates and copper-bonded electrodes?

The choice depends on your specific requirements and environmental conditions:

GI Plates: Cost-effective solution suitable for general applications with normal soil conditions. Requires periodic maintenance.

Copper-Bonded Electrodes: Higher initial cost but maintenance-free operation. Better conductivity and longer lifespan. Ideal for critical installations and corrosive environments.

Our technical team can help you select the right solution based on your soil resistivity and application requirements.

What are the standard dimensions for your cable trays?

Our cable trays come in various standard dimensions, with custom sizes available:

Width Range: 50 mm to 1000 mm (Perforated) | 100 mm to 2000 mm (Ladder)

Height Range: 25 mm to 150 mm (Perforated) | 40 mm to 150 mm (Ladder)

Standard Lengths: 2.5 meters, 3.0 meters, and 6.0 meters (custom lengths available)
