Railway Structures
Long-Term Corrosion Protection
for Rail Infrastructure
ZINGA provides cathodic protection to steel railway structures in even the most demanding environments. From tracks and bridges to stations and maintenance facilities, ZINGA extends service life, reduces maintenance costs and ensures safety and reliability.
Technical Documents
Access datasheets, guides and application information.
Railway Corrosion Challenge
Railway steel faces aggressive conditions that accelerate corrosion and increase maintenance demands.
Chlorides, Salts & Coastal Exposure
From sea spray, de-icing salts and contaminated environments.
Moisture, Condensation & Poor Drainage
Rainfall, tunnel runoff and water traps.
Vibration, Abrasion & Coating Damage
Mechanical loading can damage coatings.
Stray-Current Effects in Electrified Systems
Additional electrochemical corrosion risk.
Corrosion at Welds, Joints & Difficult Access Areas
Moisture and contaminants accumulate in crevices.
Corrosion leads to section loss, fatigue risk, costly repairs and reduced asset life.
Engineered for Rail Applications
Rail-Specific Surface Preparation
Controlled cleaning and abrasive blasting establish the required surface condition and profile.
Protection Where It Is Needed
ZINGA is applied to corrosion-prone areas such as the rail web, foot and lower surfaces. Wheel-contact areas remain uncoated where required.
Repair & Recharge
Local protection can be restored after damage or maintenance.
Designed for Installation Conditions
ZINGA coating systems are developed to withstand the demanding handling, transportation and installation of rail components.
Where ZINGA Protects the Rail
ZINGA Protection Zones
(corrosion-prone areas)
- Web (vertical surface)
- Foot
- Baseplate area
- Fasteners & supports
- Steel structures
Coating of wheel-contact areas is not recommended unless specifically required by the project.
