For industrial rail systems operating in demanding environments, surface protection is just as important as structural strength. At Glory Track, we recently completed a JIS 50N rail painting project for a client in the UAE, following strict requirements for coating performance and application standards.
This project reflects our ability to deliver not only quality steel rails, but also customized surface treatments tailored to each operating condition.
Meeting Strict Coating Requirements
For this project, the client ordered JIS 50N rails made from U71Mn steel, each measuring 10 meters in length. While the rail type was standard, the key challenge lay in the customized painting system required to protect the rails in a demanding environment.
The specification called for SA2.5 sandblasting, followed by a three-layer coating system:
two layers of epoxy zinc primer and one layer of polyurethane epoxy finish.
To meet these requirements, the rail head and joint areas had to remain uncoated, with masking applied to protect those surfaces during painting. Only the web and lower sides of the head received the full protective system.
The entire process—from surface preparation to coating and final inspection—was carried out in-house under strict quality control to ensure full compliance with the client’s standards.
SA2.5 Sandblasting: A Reliable Foundation
Effective surface preparation is critical for any long-lasting protective coating. In this project, we applied SA2.5 grit blasting to remove rust, scale, and contaminants, leaving a clean and properly textured surface ready for painting.
This level of blasting is essential in coastal, desert, and high-humidity environments, where corrosion risk is high. Without proper surface treatment, even the best coatings may fail prematurely due to poor adhesion or trapped contaminants.
Three-Layer Coating System for JIS 50N Rail Painting
After blasting, the rails were coated using a controlled three-step process:
First Layer: Epoxy zinc-rich primer, 100 microns dry film thickness
Second Layer: Additional epoxy primer coat, another 125 microns
Top Layer: Polyurethane epoxy finish coat, 125 microns
Color: RAL 7047 (Telegrey)
Total coating thickness reached 350 microns, offering excellent protection against moisture, abrasion, and chemical exposure. This system is particularly suited for long-term outdoor use in tough environments.
Masking was applied to keep the rail head and joining areas uncoated, as required. Only the rail web and part of the side head received the full protective system.
Packing and Protection for Painted JIS 50N Rails
After coating and final inspection, each bundle of JIS 50N rails was wrapped with industrial-grade protective film specially designed for steel products. This film provides excellent moisture resistance and anti-scratch protection, ensuring the coating stays intact throughout handling and shipment.
Why This Matters to Your Project?
Painted JIS rails are a practical solution for environments where corrosion is a concern.
They are ideal for applications in ports, crane tracks, outdoor storage yards, mining sites, and other exposed installations.
A high-performance paint system helps reduce maintenance and extend service life.
With in-house blasting and coating facilities, Glory Track can offer:
- Application-specific coating systems
- Custom masking and selective painting
- RAL color matching and thickness control
- Integrated production and packing for export
Our experience in executing detailed customer specifications ensures we deliver what industrial buyers truly need, not just the rail product, but the full protective solution.
Conclusion
This UAE project demonstrates more than just rail supply, it shows our ability to handle complex coating requirements with precision. From SA2.5 surface preparation to a multi-layer epoxy finish, every step was executed to meet strict quality and durability expectations.
