Using the wrong cable tray finish can lead to early rust and costly replacement. Pre-Galvanized (GP) trays ($10text{--}15text{ microns}$ zinc coating) are ideal for indoor, climate-controlled commercial office spaces.For outdoor plants, humid environments, or heavy industrial floors, Hot-Dip Galvanized (HDG) Cable Trays ($70text{--}80+text{ microns}$ zinc coating) are required. At Atul Casting & Metal Works, we manufacture both options to align with your project specifications and budget.📞 Consult our engineering sales team at +91 9873361672 or email atul.gsw@gmail.com.
