When it comes to cable trays that are durable and resilient in humid and corrosive surroundings, the galvanized option stands out as the go-to choice. The galvanizing process comes in two main forms – hot-dip and electro galvanizing (also known as cold galvanizing). Depending on the specific requirements, these production processes provide varying levels of protection against rust and corrosion. Regardless of the chosen process, investing in galvanized cable trays is an excellent decision for environments that demand robust and long-lasting infrastructure.

The process of hot dip galvanizing involves immersing steel parts or castings in molten zinc. This immersion results in the formation of a zinc ferroalloy or a coating of zinc and zinc ferroalloy on the surface of the steel. This method helps in providing a protective layer that prevents corrosion and enhances the durability of the steel components.

The cold galvanizing process involves immersing the chemically cleaned steel surface into an electroplating solution containing zinc oxide. To initiate the process, a direct current is applied with one pole connected to the steel and the other pole connected to a zinc plate submerged in the solution. As the current flows, zinc molecules are displaced and adhere to the steel surface, resulting in a molecular bond. For an enhanced finish, a cloud-like passivator can be added to the solution, resulting in a bright and glossy coating.

The effectiveness of galvanized zinc in preventing rust on steel structures is often subpar due to inadequate zinc coverage and uneven distribution. In most cases, rust can still develop within two to three years, and poor quality galvanized coatings may even succumb to humid environments within just a few days. Hot-dip galvanized coatings, on the other hand, are much thicker and offer significantly stronger protection against corrosion. Although cold galvanized coatings may appear brighter, they are generally much thinner and thus have weaker corrosion resistance.
