The Impact of Cable Tray Rust
The primary function of a cable tray is to be a durable, efficient and resistant support. A recurring theme in all metal applications, uncontrolled corrosion can result in poorer performance and affect the installation's life expectancy, through chemical or electrochemical. There is a solution for each type of environment. This white paper compares the High Resistance (HR) and Hot-Dip Galvanising (HDG) solutions and highlights the new High Resistance range, ZnAl wiremesh, ZnMg metal cable trays and accessories and ZnNi screws and bolts. However, exposure to harsh environments can lead to corrosion, compromising their structural integrity and safety. According to investigations, many customers find that the cable trays they purchased start to rust shortly after. Corrosion is a common concern in cable tray systems, particularly in industrial environments where exposure to harsh conditions like moisture, chemicals, and temperature fluctuations is prevalent.
