What Is RAL Color, and What Types Are There?
RAL is a color-matching system widely used across Europe, especially in the paint and coating industry. RAL color codes ensure consistency and accuracy when choosing colors for a wide range of products, from wall paint to industrial materials such as cable trays, cable ladders, wire mesh trays, and electrical enclosures.
The RAL system is an international color standard offering a broad palette with specific color codes. It is used extensively across many industries, including powder coating.
What RAL stands for: RAL is short for “Reichsausschuss für Lieferbedingungen” (the German National Committee for Delivery Terms and Quality Assurance).
Types of RAL color systems:
- RAL Classic: The most basic and widely used color system, comprising more than 200 different colors.
- RAL Design: An extended color system offering a wider, more modern range of colors.
- RAL Effect: A special color system focused on surface effects such as metallic, sheen, or other special finishes.
This article covers only RAL Classic (also called the basic/standard RAL palette). Cable trays and ladders generally have no special color requirements, so the RAL Classic system is sufficient. In practice, only about 10 colors or fewer are typically used for painting cable trays and ladders. Still, let’s take a full look at this color chart. RAL Classic is divided into 9 groups numbered from 1xxx to 9xxx, where “xxx” represents the specific numbers. Below is a summary table of the standard color groups:
| Code range | Color group | First color | Last color | Number of colors in range |
|---|---|---|---|---|
| RAL 1xxx | Yellow | RAL1000 | RAL1037 | 30 |
| RAL 2xxx | Orange | RAL2000 | RAL2017 | 14 |
| RAL 3xxx | Red | RAL3000 | RAL3033 | 25 |
| RAL 4xxx | Violet | RAL4001 | RAL4012 | 12 |
| RAL 5xxx | Blue | RAL5000 | RAL5026 | 25 |
| RAL 6xxx | Green | RAL6000 | RAL6039 | 37 |
| RAL 7xxx | Gray | RAL7000 | RAL7048 | 38 |
| RAL 8xxx | Brown | RAL8000 | RAL8029 | 20 |
| RAL 9xxx | Black/white | RAL9001 | RAL9023 | 15 |
Here Are the 9 Basic RAL Color Groups
The basic RAL palette, also called RAL Classic, is the most commonly used color system. Later, extended systems were developed — RAL Design and RAL Effect, as noted above. This article covers only RAL Classic, not the extended systems.
- RAL 1000-1037
- RAL 2000-2017
- RAL 3000-3033
- RAL 4001-4012
- RAL 5000-5026
- RAL 6000-6039
- RAL 7000-7048
- RAL 8000-8029
- RAL 9001-9023
Why Use RAL Colors?
- Consistency: Makes it easy to compare and choose colors across different manufacturers and projects.
- Accuracy: RAL codes provide a specific, easily recognizable color standard.
- Wide adoption: Used extensively across many industries.
Common Powder-Coating Color Chart
In powder coating, the RAL Classic palette is the most widely used. RAL colors are commonly applied to products such as:
- Interior: Window frames, railings, metal furniture.
- Exterior: Building façades, fences, canopies.
- Industrial: Machinery, equipment, chassis frames, cable trays and ladders.
Notes When Comparing Powder-Coating Colors With the RAL System
- Not every powder-coating color has an exact match in the RAL chart.
- When choosing a powder-coating color, you can use the RAL chart as a reference to get an idea of the color you want.
- To ensure color accuracy, ask the manufacturer for a paint sample before making a final decision.
- RAL 7032 and RAL 7035 are the most frequently requested colors for cable trays, ladders, and electrical enclosures.
You can find a detailed, complete RAL color chart at: RAL Color (ralcolor.com).
Note: When choosing a powder-coating color, it’s worth consulting with specialists to make sure the color suits the space and intended use.
FAQ About the RAL Color Chart and Powder Coating at The Sun
What is the RAL color chart, and why does it matter in cable tray manufacturing?
The RAL color chart is an international (German) color standard that unifies color codes between design and manufacturing. At The Sun, we apply the RAL standard to ensure our powder-coated cable trays and ladders have consistent color across every batch and every project.
Which RAL color codes are most commonly used for cable trays and ladders?
Based on the practical needs of electrical and mechanical projects, the most common codes include:
- RAL 7032, RAL 7035 (Light gray): The standard choice for substations and electrical enclosures.
- RAL 2004 (Orange): Used for low-voltage systems, fire protection, or warning markings.
- RAL 5012, RAL 5015 (Blue): Used to distinguish signal cabling.
- RAL 9003, RAL 9005: White or black for spaces requiring a high level of finish.
Does The Sun accept powder coating in a custom RAL color code?
Yes. Because we operate our own powder-coating line in Binh Duong, The Sun can mix and match any RAL color code to a customer’s specific technical requirements, including special colors outside the common catalogue.
How long does production and finishing take at the workshop?
Because we control the entire process in-house — from laser cutting and CNC bending to powder coating — we keep lead times as short as possible. Powder-coating orders are typically completed within 3–5 business days.
