1. What Is A HDG Cable Ladder?

A HDG (Hot Dip Galvanized) cable ladder is a robust and versatile cable tray system used for supporting and organizing electrical cables within buildings and facilities. It consists of steel rungs that are welded together to form a ladder-like structure. To protect it from rust and corrosion, the steel ladder undergoes the hot-dip galvanization process, where it is immersed in a bath of molten zinc.

Galvanization is a widely employed method for safeguarding metal surfaces, and in the case of HDG cable ladders, it involves coating the steel with a layer of zinc. This protective coating significantly enhances the ladder’s resistance to corrosion, ensuring its durability even in harsh environments. The process of hot-dip galvanization typically takes several days, including fabrication, galvanization, and preparation for final shipment. Traditionally, cable tray manufacturers have to send their products to third-party galvanizers, which adds time and cost to the manufacturing, packing, and shipping processes.

As one of the largest cable tray manufacturers in China, JLH Electric has been authorized by the government to have their own cable tray manufacturing and hot-dip galvanizing workshops. This allows them to guarantee the quality and stability of their hot-dip galvanized steel products and increase their production capability, especially for large-span cable trays.

HDG cable ladders offer several advantages compared to other HDG cable tray systems, particularly when supporting high volumes or heavy cabling over long spans. The ladder design provides increased strength and load-bearing capacity, making it well-suited for applications where substantial amounts of cabling need to be supported over extended distances.

The versatility of HDG cable ladders makes them suitable for various cable support and management applications across different industries. They are commonly utilized in industrial settings, power plants, commercial buildings, data centers, and other installations where effective cable organization and support are essential for maintaining efficient operations.

HDG cable ladders are durable, versatile, and cost-effective cable tray systems that undergo a hot-dip galvanization process to enhance their corrosion resistance. With their robust ladder design and suitability for high volumes and long spans, they find wide-ranging applications in cable support and management across diverse industries.

2. What Are Benefits of HDG Cable Ladders?

HDG cable ladders offer corrosion resistance, durability, strength, versatility, environmental friendliness, and easy installation. These benefits make them an ideal choice for organizations seeking long-lasting, cost-effective, and reliable solutions for their cable support and management needs.

2.1 Corrosion Resistance

The hot-dip galvanization process provides a thick and durable zinc coating, ensuring superior corrosion resistance. HDG cable ladders can withstand harsh and corrosive environments, making them highly durable and long-lasting.

The galvanization process enhances the durability of HDG cable ladders. By coating the steel with a layer of zinc, the trays become highly resistant to corrosion, impacts, and other forms of wear and tear. This results in a long-term investment that provides reliable and long-lasting cable management solutions.

2.4 Strength

HDG cable ladders are engineered using solid steel, which adds strength to the product. This design allows them to support heavy cable loads and withstand mechanical stress. The inherent strength of the galvanized steel ensures the overall stability and structural integrity of the cable ladder system.

2.5 Versatility

HDG cable ladders are versatile and suitable for various applications. They can be effectively used in power distribution, data centers, manufacturing facilities, industrial settings, and more. This versatility allows for flexible and efficient cable management solutions in diverse environments.

2.6 Environmental Friendliness

The galvanization process is environmentally friendly. It has a minimal impact on the environment, consumes less energy, and generates negligible waste. By choosing HDG cable ladders, organizations can contribute to sustainable practices and reduce their carbon footprint.

2.7 Cost effective

HDG cable ladders are cost-effective due to their longevity, durability, reduced maintenance, prevention of cable damage, versatility, ease of installation, and lower total cost of ownership. They provide an inexpensive solution for cable support compared to alternatives.

2.8 Easy Installation

HDG cable ladders are designed for easy installation, requiring fewer human resources and less time. This simplifies the process for industries managing cables in industrial or commercial buildings. The straightforward installation procedures ensure efficient and convenient cable support and management.

3. What Is Difference Between Pre-galvanized And HDG Cable Ladder?

The differences between pre-galvanized and HDG cable ladder can be attributed to factors such as coating thickness, corrosion resistance, surface properties, mechanical strength, and cost. Pre-galvanized cable ladders have a thinner zinc coating, typically around 20 microns, while hot dip galvanized (HDG) cable ladders have a much thicker coating, ranging from 55 to 85 microns on average. This difference in coating thickness provides varying levels of protection against corrosion.

3.1 Different Manufacturing Process

Pre-galvanized cable ladders are coated with zinc before being formed into the cable tray shape, which may result in limited coating on crevices and cut edges. In contrast, HDG cable ladder are formed first and then submerged into a molten zinc bath, ensuring a more comprehensive and even coating.

3.2 Different Corrosion Resistance

HDG cable ladder offers superior protection and durability. It can last up to 25 years or even longer, depending on the environment, making them suitable for harsh conditions. Pre-galvanized cable ladder provides less protection and have a shorter lifespan of around 2.5 to 7 years, making them more suitable for mild environments.

3.3 Different Surface properties

Pre-galvanized cable ladder tend to have a smoother finish due to the thinner coating, while HDG cable ladder may have a slightly rougher texture due to the thicker coating.

3.4 Different Mechanical strength

HDG cable ladder generally exhibits higher strength and load-bearing capacity compared to pre-galvanized cable ladder.

3.5 Different Cost

Pre-galvanized cable ladder may have a lower initial cost due to the thinner coating. However, considering the superior corrosion resistance and longer lifespan of hot dip galvanized cable ladder, it often provides a better long-term investment.

4. How Thick Is A HDG Cable Ladder?

The thickness of a HDG (Hot-Dip Galvanized) cable ladder refers to the base steel material, not the zinc coating itself. The zinc coating thickness is typically in the range of 55 microns to 85 microns for hot-dip galvanized cable ladders, and it primarily contributes to corrosion resistance rather than overall thickness.

The base steel thickness of a HDG cable ladder can vary depending on the manufacturer, ladder size, and intended load capacity. Common thicknesses for hot-dip galvanized cable ladders include:

1.0 mm: This thickness is often used for lighter weight cable loads where the ladder doesn’t need to support significant weight.

1.5 mm: This thickness strikes a good balance between strength and weight. It is commonly used for various applications where moderate load capacity is required.

2.0 mm or higher: These thicker base steel materials are utilized for heavier cable loads. They provide increased strength and rigidity to support the weight of more substantial cables.

The choice of base steel thickness depends on factors such as the anticipated weight of the cables, load capacity requirements, and industry standards. Manufacturers typically offer a range of options to accommodate different installation needs. The zinc coating thickness and the base steel thickness are separate considerations when evaluating the overall durability and performance of a HDG cable ladder.
