To shield steel rails from ultraviolet (UV) radiation, they undergo a process called galvanization. This process involves coating the steel with a layer of zinc, which can be achieved through either hot-dip galvanization or electroplating. The zinc layer serves as a barrier, safeguarding the steel from direct exposure to the detrimental effects of UV rays.
Over time, UV radiation from the sun can cause harm to the steel rails, resulting in corrosion and deterioration. However, the zinc coating acts as a sacrificial layer, corroding before the steel does. This sacrificial corrosion, referred to as cathodic protection, guarantees that the steel rails remain shielded from the harmful impact of UV radiation.
In addition to galvanization, steel rails can also be safeguarded against UV radiation by applying a protective coating or paint. These coatings are specifically designed to provide an extra layer of defense, preventing direct contact between the steel surface and UV rays. By acting as a barrier, these coatings diminish the risk of corrosion and extend the lifespan of the steel rails.
To ensure the ongoing protection of steel rails against UV radiation, regular maintenance and inspection are crucial. Any indications of damage or deterioration should be promptly addressed to prevent further corrosion and uphold the integrity of the protective coating. By implementing these protective measures, steel rails can effectively be shielded from the detrimental effects of UV radiation, guaranteeing their long-term durability and safe operation.

UV radiation from the sun can cause damage to the steel rails over time, leading to corrosion and deterioration. The zinc coating acts as a sacrificial layer, meaning it corrodes before the steel does.

In addition to galvanization, steel rails can also be protected from UV radiation by applying a protective coating or paint. These coatings are specifically designed to provide an additional layer of protection against UV rays, preventing direct exposure to the steel surface. The coating acts as a barrier, reducing the potential for corrosion and extending the lifespan of the steel rails.
Regular maintenance and inspection are essential to ensure the continued protection of steel rails from UV radiation. Any signs of damage or deterioration should be promptly addressed to prevent further corrosion and maintain the integrity of the protective coating. By implementing these protective measures, steel rails can be effectively shielded from the harmful effects of UV radiation, ensuring their longevity and safe operation.
Steel rails are typically coated with a layer of paint or a protective coating that acts as a barrier against ultraviolet radiation. This coating helps to prevent the rail from experiencing damage or degradation caused by the sun's UV rays.
