What type of cable trays are used in corrosion-resistant rooms
For such settings, anti-corrosive cable trays made from galvanized steel or aluminum alloy are excellent choices. Both materials offer adequate protection against light corrosion while being cost-effective and easy to install. 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. In the cable tray industry, corrosion protection is critical because cable trays, supports, and related components are often exposed to harsh environmental conditions. Understanding corrosion classes helps manufacturers and engineers select the right materials and protective coatings for these.

How to prevent dust from coal conveying cable trays
There are a wide range of techniques available to control and prevent dust from becoming problematic. Misting cannons have become the predominant method for dust management based on their ease of use, cost-effectiveness and proven success. Coal handling plants (CHPs) generate significant amounts of dust during processes such as coal crushing, screening, loading, unloading. In today's episode of the Dust Safety Science podcast, David Wood, Senior Technical Advisor at Benetech Inc., discusses redesigning chutes and conveyor systems to reduce fugitive dust. Coal dust is a contributor to lung disease and it therefore poses a threat to not only workers in these facilities but even to residents of. Fugitive dust on conveying systems is an ongoing issue faced by mines, transfer stations and utilities transporting, processing or burning coal, writes Mark Strebel, Division Manager, Martin Engineering. Effective dust control has become an increasingly important challenge, with raised awareness. Effective dust control in mining involves a combination of strategies tailored to specific operations and environments.
