The production process of cable ladders and cable trays is a process that many people are curious about. Because not everyone understands the steps to make this special ladder. So let’s find out with P69 Mechanical Factory.
What is a cable tray?
Cable tray ladder, also known as cable ladder, electric ladder or cable ladder is a guide ladder used for the installation of electric cable systems, wires, auxiliary for the construction industry, electricity … of construction works such as schools, apartment buildings, buildings, offices, factories…

Cable tray ladder material
Ladder Cable Tray are usually made from sheet metal. After that, depending on the requirements of each project, the surface will be covered with protective layers. For anti-corrosion, anti-rust, increases aesthetics.
1. Powder coated cable tray
Is the leading modern coating technology today and is also the most popular in all industries. With many advantages. This is the first choice for cable tray products, trusted by many units.
– Advantages:
- Has a high aesthetic value, the product surface can be smooth or rough.
- Rich colors: there are always many colors to choose from.
- Affordable cost.
- Fast painting time, responding to orders with urgent progress.
– Disadvantages:
- Low corrosion resistance should only be used with indoor products.
– Note: Although it is an advanced coating technology, in order to reduce production costs and create competition, the cable tray ladders usually use simple coating technologies. It greatly affects the quality and life of the paint layer. So make sure to strike a balance between cost and quality.
2. Hot dipped galvanized cable tray ladder
Is a technology to cover the surface of the material with a protective layer of zinc. Specialized for outdoor cable tray ladders thanks to good corrosion resistance. Resistant to extreme weather conditions. Long coating life. You can easily come across high-voltage poles all using this hot-dip galvanizing technology.
– Advantages:
- Very good plating durability, no peeling. Long lifespan.
- High resistance to corrosion and wear. Good anti-rust.
- Unaffected by extreme weather conditions.
– Disadvantages:
- The very high cost is the major drawback.
- The surface of the coating is rough. Matte galvanized color, not shiny. Making low aesthetics is also a small minus point.
- There is only one bright silver color of the zinc layer.
– Note: One point to remember is that hot-dip galvanized products must have a large, corrugated iron thickness. Due to many reasons, during hot-dip galvanizing, the material will deform (curve-warp-distort). Strongly affect product quality.
3. Electroplated cable tray
Similar to hot-dip galvanizing, electroplating also coats a layer of zinc on the surface of the material. But the coating quality is much lower. Because the coating is thin, the adhesion to the material is not high.
– Advantages:
- High resistance to corrosion and wear. Good anti-rust.
- The surface of the product after plating is smooth, shiny, creating high aesthetics.
- Low cost.
– Disadvantages:
- The plating is thin, the durability is not high, it is easy to be scratched.
- There is only one bright silver color of the zinc layer.
4. ZAM corrugated iron cable tray
Zam tole is an alloy of Steel – Zinc – Magnesium. Has higher corrosion resistance than ordinary galvanized steel. Cable tray ladder made from Zam corrugated iron has the same properties as electroplating. However, thanks to the direct construction on Zam corrugated iron, reducing the process of coating materials and labor. As a result, the cost of the product is very low.
– Advantages:
- Very low cost.
- Fast production time.
- High resistance to corrosion and wear. Good anti-rust.
- The product surface is smooth, shiny, creating high aesthetics.
– Disadvantages:
- The plating is thin, the durability is not high, it is easy to be scratched.
- There is only one bright silver color of the zinc layer.
5. Aluminum cable tray ladder
Always use aluminum sheet to make cable tray ladder. Due to the nature of aluminum being shiny, and having a high inertness, there is no need to apply additional protective material on the outside.
– Advantages:
- Product weight is very light.
- Fast production time.
– Disadvantages:
- Poor strength, easy to deform.
- Highly aesthetic but very easy to scratch during construction.
- The very high price is a big minus.
– Note: The advantages are too few compared to the disadvantages that make aluminum not a good choice. Therefore, not many units use this material as cable tray ladder.

Production process of cable ladders, cable trays
The detailed product manufacturing steps are as follows:
Step 1: Calculate the optimal size of cable ladder and cable tray
Before production, it is necessary to calculate the size of cable ladders and cable trays to suit the technical requirements of the project.
This will ensure that the manufactured cable ladder and cable tray have enough space to arrange and manage all kinds of conductors.
As well as ensuring the certainty and durability of the product during operation and use.
Step 2: Choose the right type of cable ladder and cable tray
In order for products to meet quality standards and save costs, choosing the type of cable ladder and cable tray plays an extremely important role.
Depending on the technical requirements of the customer, the manufacturer will process one of the following types:
– Cable ladder
– Cable tray
– Cable tray (perforated cable tray)
And choose materials and surface treatment according to environmental conditions:
– Cable tray ladder using powder coated black corrugated iron
– Cable tray ladder using hot-dip galvanized black corrugated iron
– Cable tray ladder using electroplated black corrugated iron
– Cable tray ladder using zam corrugated iron
– Cable tray ladder using aluminum sheet
In addition, the manufacturer must check the details of the thickness, width and length of the details before deploying the design/construction drawings.
After having agreed with the customer the appropriate design. The production unit transfers construction drawings to the workshop for production.
Step 3: Cut the workpiece according to the calculated size
Depending on the size of the cable ladder, cable tray, workers cut corrugated iron into accurately calculated billets. Ton ensures smooth, no rust, warping. The thickness of corrugated iron is sufficient with the requirements of the customer.
Step 4: Processing punching holes according to product requirements
The billets are put on the CNC machine to punch holes according to the design drawings. With CNC machines, cable tray ladder products have high aesthetics and accuracy, helping to improve product quality and accuracy in the installation process.
Step 5: Fold and shape the product
The billet after punching will be transferred to the bending machine, folded according to the designed dimensions and structure. For the product that is a cable ladder, at this stage it is necessary to weld the shaped details to create a solid product.
Step 6: Check the raw product before surface coating
Raw products – after being finished processing, the details of joints and welds will be carefully checked; the specifications such as length, product width. After meeting the requirements, the raw product will be subjected to surface treatment.
Step 7: Clean, wash and paint the surface of the product
Depending on the technology (powder coating, hot dip galvanizing, electroplating, …) the raw product will be thoroughly cleaned according to the standards. This is a very important step to ensure the finished product has a beautiful and durable coating over time. After cleaning, the product is painted with a surface coating according to the requirements of the customer.
Step 8: Check, pack, deliver products to customers
The finished product is subjected to a final quality check. The product must fully meet the design size criteria; firm structure, no warping, denting; the coating layers are even, smooth, beautiful before shipment. The product is then carefully packaged and delivered to the customer.
