Galvanized ladder cable trays are widely used in manufacturing plants, data centers, and infrastructure projects, where they offer a robust and cost-effective solution for cable management. Their corrosion resistance, durability, and ease of installation make them a preferred choice for organizing and protecting electrical cables in a variety of applications.

2. What Is The Construction Of Galvanized Ladder Cable Trays?

2.1 Materials

  • Primary Material:Galvanized steel is the foundation. Q235 Steel offers inherent strength and rigidity to support cable loads.
  • Galvanization Process:The steel undergoes a pre-galvanized or hot-dip galvanization process. The hot dip galvanization dips the steel ladder into a molten zinc bath at high temperatures. The zinc reacts with the steel to form a protective zinc coating.

2.2 Structural Components

  • Rungs:These are the horizontal bars on the sides of the galvanized ladder cable trays. They provide a platform for resting and routing cables.
  • Side Rails:These are the vertical bars that run along the sides of the galvanized ladder cable trays, providing the main structure and support.
  • Mounting Bars (Optional):Some galvanized ladder cable trays have flat bars running along the bottom or back. These are used for secure mounting on walls, ceilings, or other supporting structures.

2.3 Additional Elements

  • Pre-cut Sections:Galvanized ladder cable trays typically come in pre-fabricated sections of standardized lengths. This allows for easier installation and modularity.
  • Connection Hardware:Depending on the design, there might be pre-drilled holes or specific connection points for joining multiple sections together seamlessly.
  • Accessories: Cross, tee, bend, joint end, and risers are the main accessories of galvanized ladder cable trays, and the quantity applied for each would depend on the design of cable tray system on the site.
  • Coating Thickness:The zinc coating on the steel has a measurable thickness, typically specified in microns (µm). The thickness determines the level of corrosion resistance (thicker coatings offer better protection in harsh environments).

2.4 Manufacturing Process

  • Steel Fabrication:The steel is formed into the desired ladder shape, including rungs, side rails, and any mounting bars.
  • Surface Preparation:The steel surface is prepared to ensure proper adhesion of the zinc coating.
  • Hot-Dip Galvanization:The steel ladder is dipped into a molten zinc bath, creating a uniform zinc coating on the entire surface.
  • Quality Control:The finished product undergoes quality checks to ensure proper coating thickness, structural integrity, and dimensional accuracy.
  • Pre-cutting (if applicable):The ladder may be cut into pre-defined lengths for easier handling and installation.

Overall, the construction of galvanized ladder cable trays combines the strength and formability of steel with the superior corrosion resistance of a hot-dip zinc coating. This creates a robust and durable cable management solution suitable for its various applications.

3. What Are The Key Features Of Galvanized Ladder Cable Trays?

3.1 Corrosion Resistance

The galvanized steel construction provides a protective zinc coating that effectively resists corrosion, ensuring the long-term durability and performance of the cable trays.

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

Here’s a breakdown in zinc coating thickness for the two main materials and surface treatments:

3.1.1 Pre-galvanized Steel Q235

This is the most common galvanized ladder cable tray and cost-effective option. The steel is pre-treated and then coated with zinc during its manufacturing process. Pre-galvanized ladder cable trays 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. The pre-galvanized ladder cable tray is usually adopted in the following applications:

  • 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.

3.1.2 Hot Dip Galvanized Steel Q235

The galvanized ladder cable tray of hot dip galvanized steel Q235 is mainly used for outdoor purpose that requires high anti-corrosive performance and more service life.

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 the galvanized ladder cable trays, 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 galvanized ladder cable tray 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 ladder cable trays, Since Coating Thickness: 50-100 microns, Minimum 460 g/m² (thicker coating) – Offers better protection for harsher conditions

3.2 Durability With Heavy Loads

Galvanized steel is a highly durable material that can withstand heavy loads, harsh environments, and physical impacts, making the cable trays suitable for industrial and commercial applications.

The load capacity of a galvanized ladder cable tray 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

3.3 Cost-Effectiveness

Compared to other cable management solutions, galvanized ladder cable trays offer a more affordable option without compromising quality and reliability.
