2. What Are The Benefits Of Gi Cable Ladder?

Gi cable ladders offer a multitude of benefits in cable management, particularly in environments prone to corrosion and harsh conditions. The process of galvanization, which involves coating the steel with a protective layer of zinc, ensures exceptional durability and longevity. Here are the key advantages of using Gi cable ladders:

2.1 Unparalleled Durability

The galvanization process provides excellent resistance against moisture, rust, and environmental factors, ensuring long-lasting performance and minimal maintenance requirements. This makes Gi cable ladders highly durable and suitable for demanding applications.

2.2 Lightweight and Cost-Effective

Gi cable ladders are fabricated from lightweight structural grade aluminum extrusions, offering a superior strength-to-weight ratio. This makes them lighter than steel alternatives, facilitating easier installations and reducing costs.

2.3 Extended Spans

Gi cable ladders can span significant distances without additional supports, reducing the need for structural steel supports and lowering the overall installation cost. This advantage can be particularly beneficial in large-scale projects.

2.4 Outstanding Corrosion Resistance

Gi cable ladders exhibit excellent resistance to corrosion, making them suitable for use in chemical environments and coastal petrochemical plants. They can perform effectively and maintain their integrity over time, even in challenging conditions.

2.5 Versatility

Gi cable ladders are highly versatile and can be utilized in a wide range of applications. They excel in heavy industrial settings where environmental conditions, such as wind, snow, and ice, pose significant load requirements.

2.6 High Load Capacity

Designed to handle high cable loads, Gi cable ladders are capable of withstanding extreme cable and environmental load conditions. They utilize long spans to decrease support costs and provide robust support for heavy cables.

2.7 Easy Installation and Maintenance

Some Gi cable ladders incorporate innovative designs, such as I-Beam side rails, which increase load capacity while reducing weight. This not only facilitates easier installation but also simplifies maintenance tasks.

These advantages position Gi cable ladders as a preferred choice for cable management in various applications, including industrial, commercial, and offshore settings where durability, strength, and cost-effectiveness are crucial factors to consider.

3. What Are The Key Considerations When Choosing Gi Cable Ladders?

When selecting Gi cable ladders, several critical factors require careful consideration. Thoroughly evaluating these factors will help you choose the most appropriate solution for your specific application. Key considerations include:

3.1 Load Capacity

The load capacity of a Gi 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

3.2 Ladder Size and Dimensions

The size and dimensions of the Gi 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 Gi cable ladders:

  • Width: 75mm-800mm
  • Height: 50mm-300mm
  • Length: 2400mm-8000mm
  • Thickness: 1.0mm-2.5mm

3.3 Material and Coating Thickness

The thickness of the zinc coating on a Gi cable ladder is measured in microns (µm).The choice of material and coating thickness for the Gi 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 Gi cable ladders are two crucial factors influencing their durability, corrosion resistance, and suitability for your specific application.

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.

3.4 Environmental Considerations

The environmental conditions in which the Gi 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.Gi cable ladder is more suitable for Indoor purpose, Dry Environments, and the Minimum thickness of 55 µm is sufficient. This is often referred to as G30 in the US standard (ASTM A653)

3.5 Installation Method and Accessories

The installation method and accessories required for the Gi 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.

3.6 Regulatory Compliance

Ensure that the selected Gi 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.
