With a track record of successfully completing more than 50 overseas projects, their galvanised cable ladders have proven to be reliable and of high quality.

Whether in manufacturing plants, data centers, or infrastructure projects, galvanised cable ladders offer a robust solution for cable management. Their corrosion resistance, durability, and cost-effectiveness make them a preferred choice for organizing and protecting electrical cables in various applications.

2. What Are The Key Considerations To Choose Galvanised Cable Ladder?

When embarking on the journey of selecting galvanised cable ladders, a multitude of factors demand careful consideration. These considerations , if meticulously evaluated, will guide you towards the most suitable solution for your specific application, and the important factors to consider are as follows:

2.1 Load Capacity

The load capacity of a galvanised cable ladder signifies its ability to bear the weight of the cables it supports. This parameter is of paramount importance, as exceeding the load capacity can lead to structural failure, posing safety hazards and disrupting operations. Accurately assessing the weight of the cables to be supported is essential for selecting a cable ladder with adequate load-bearing capacity.

  • The safe working load(SWL)is 1000(N/m)if the side height is 100mm
  • The safe working load(SWL)is 1850(N/m)if the side height is 150mm
  • The safe working load(SWL)is 3100(N/m)if the side height is 200mm

The above load is based on the standard JBT10216-2013

2.2 Ladder Size and Dimensions

The size and dimensions of the galvanised cable ladder play a pivotal role in ensuring efficient cable management and organization. The width of the ladder should be sufficient to accommodate the number and size of cables, while the depth should provide ample clearance for easy installation and maintenance. Additionally, consider the ladder’s length to ensure it spans the required distance effectively.

JLH electric can customize the following sizes of galvanised cable ladder:

  • Width: 50mm-800mm
  • Height: 50mm-250mm
  • Length: 2000mm-8000mm
  • Thickness: 1.0mm-2.5mm

2.3 Material and Coating Thickness

The thickness of the zinc coating on a galvanised cable ladder is measured in microns (µm).The choice of material and coating thickness for the galvanised cable ladder is crucial for achieving the desired level of corrosion resistance. In environments with high humidity or exposure to corrosive substances, thicker zinc coatings are recommended. The material and coating thickness of galvanised cable ladders are two crucial factors influencing their durability, corrosion resistance, and suitability for your specific application.

Here’s a breakdown of both aspects:

2.3.1 Pre-galvanised Steel

This is the most common and cost-effective option. The steel is pre-treated and then coated with zinc during the manufacturing process.

Coating Thickness

Pre-galvanised cable ladders typically have a zinc coating thickness of around 20 microns (µm).

This thickness falls under a category sometimes referred to as Zg275 (based on EN 10346 standard) and offers a basic level of corrosion resistance. It’s suitable for:

  • Indoor, dry environments:Places like offices, warehouses, and commercial buildings with minimal humidity.
  • Controlled environments:Areas with moderate humidity and minimal exposure to corrosive elements.

2.3.2 Hot Dip Galvanized Steel

The typical zinc thickness for hot-dip galvanised cable ladders is between 50-100 microns (0.05-0.1 mm).

The hot-dip galvanization process coats the steel with a layer of zinc to provide corrosion protection. The thickness of the zinc layer can vary depending on factors such as the steel composition, the galvanization process parameters, and the intended application.

For cable ladders, which are used to support and route cables in industrial and infrastructure applications, a zinc thickness in the 50-100 micron range is common. This provides a good balance of corrosion resistance, durability, and cost-effectiveness for this type of product.

The actual zinc thickness for a specific cable ladder product may fall within this general range or could be slightly higher or lower depending on the manufacturer’s specifications and the intended use case. But 50-100 microns is a good rule of thumb for the typical zinc coating thickness on hot-dip galvanized steel cable ladders.

Coating Thickness: 50-100 microns, Minimum 460 g/m² (thicker coating) – Offers better protection for harsher conditions

2.4 Environmental Considerations

The environmental conditions in which the galvanised cable ladder will be installed must be carefully evaluated. Factors such as temperature, humidity, and exposure to chemicals or pollutants can influence the selection of material, coating thickness, and mounting hardware.

Here’s a general guideline for selecting the appropriate thickness based on the environment:

Indoor, Dry Environments: Minimum thickness of 55 µm is sufficient. This is often referred to as G30 in the US standard (ASTM A653)

Outdoor or Humid Environments: A minimum thickness of 70 µm or higher is recommended. This corresponds to G90 in the US standard, offering better protection against moisture and corrosion.

Highly Corrosive Environments: For environments with high humidity, exposure to chemicals, or coastal locations, even thicker coatings exceeding 85 µm might be necessary.

Additional Considerations:

Standards: Ensure the galvanised cable ladder meets relevant industry standards like ASTM A653 (US) or BS EN 61537 (Europe) for material and coating specifications.

Manufacturer’s Recommendations: Reputable manufacturers often provide recommendations on material and coating thickness based on the intended application.

2.5 Installation Method and Accessories

The installation method and accessories required for the galvanised cable ladder should be compatible with the mounting surface and the overall system design. Consider the availability of mounting brackets, support structures, and other accessories that align with your installation requirements.

2.6 Regulatory Compliance

Ensure that the selected galvanised cable ladder adheres to all applicable safety standards and building codes. This includes compliance with fire safety regulations, electrical codes, and load-bearing requirements specific to your region or industry.

3. What Is The Significance Of Galvanised Cable Ladder?

galvanised cable ladders excel in environments prone to corrosion and harsh conditions, offering unparalleled durability and longevity. The galvanization process involves coating the steel with a protective layer of zinc, effectively shielding it from the detrimental effects of moisture, rust, and other environmental factors. This renders galvanised cable ladders ideal for both indoor and outdoor applications, ensuring long-lasting performance and minimal maintenance requirements

4. How To Install Galvanised Cable Ladder?

galvanised cable ladders are typically installed by suspending them from the ceiling or mounting them on walls using support brackets.

Installing galvanised cable ladder requires careful planning and execution to ensure a safe and functional cable management system. Here’s a general guide on the process, but remember to consult instructions and relevant safety regulations with JLH electric-one of the leading manufacturers of galvanised cable ladders in China for your specific product and location.

4.1 Gather Materials
