The rail is the main component of railway tracks. Its function is to guide the wheels of locomotives and vehicles forward, bear the immense pressure of the wheels, and transmit this pressure to the sleepers. Rails must provide a continuous, smooth, and low-resistance rolling surface for the wheels. In electrified railways or automatic block sections, rails can also serve as a track circuit.
Features and Advantages
Excellent corrosion resistance performance
● The galvanized layer can block oxygen and moisture in the air, preventing oxidative reactions on the surface of the rail.
● Under normal conditions, the service life of galvanized steel rails is extended by more than 3 to 5 times compared to ung galvanized steel rails.
● It is particularly suitable for high-corrosion environments such as coastal areas, chemical plants, and mining areas.
01
Type of craft
● Hot-Dip Galvanizing
• Steel tracks are immersed in molten zinc to form a uniform zinc-iron alloy layer and a pure zinc outer layer.
• The thickness of the galvanized layer is typically between 50-200μm, with excellent corrosion resistance, making it suitable for heavy loads and harsh environments.
● Electro-Galvanizing
A zinc layer is formed on the surface of the steel rail through the electroplating process, with a relatively thin coating (usually <50μm), suitable for mild corrosion environments or decorative purposes.
02
Surface aesthetics and low maintenance costs
● The surface of the galvanized steel rails is smooth and shiny, with a metallic luster and a neat appearance.
● Even if there are slight scratches on the surface, the zinc layer can still provide cathodic protection to the internal steel, delaying the spread of corrosion.
● This reduces the need for frequent maintenance and replacements, lowering long-term operating costs.
03
Environmental Protection and Recyclability
● Galvanized steel meets environmental protection requirements, and the galvanized layer itself is non-toxic and can be fully recycled.
● The high recycling rate of the steel itself (over 95%) further enhances the sustainability of galvanized steel rails.

Application scenarios
Rail Transit
Infrastructure such as subways, high-speed rail, and light rail, especially in humid or coastal cities.
Mining and Quarries
To resist corrosion from high humidity and ore dust.
Ports and Docks
Used for gantry cranes and container crane tracks, resistant to seawater corrosion.
Industrial Buildings
Used in environments with high corrosion, such as chemical plants and steel mills.
Galvanized Steel Rails vs. Ordinary Steel Rails
| Feature | Galvanized Steel Rails | Ordinary Steel Rails |
|---|---|---|
| Corrosion Resistance | Excellent, suitable for harsh environments (e.g., coastal, industrial, high-humidity areas) | Standard, requires additional anti-corrosion measures (e.g., painting, regular maintenance) |
| Service Life | 15+ years (depending on environmental conditions) | 8-10 years (requires regular rust prevention and repainting) |
| Surface Treatment | Hot-dip galvanizing or electro-galvanizing (provides long-lasting zinc protection) | No special treatment or only basic coatings (limited protection) |
| Maintenance Cost | Low, fewer maintenance requirements due to durable zinc coating | Higher, requires frequent rust removal and repainting |
| Initial Cost | Slightly higher (due to advanced anti-corrosion treatment) | Lower initially, but higher long-term costs due to maintenance |
