Hot-Dip Galvanized Vs Aluminum Cable Trays in Outdoor Application - Hutaib Electricals
02-June-2021 || By: Admin
One of the main reasons to make a decision when planning a cable tray system for corrosive or open air conditions is that the material.
Steel cable tray
with a Hot-Dip Galvanized after Fabrication finish has been utilized effectively for quite a while. Increasingly, however, aluminum is becoming the fabric of choice for cable tray systems. In these days of shrinking construction budgets, why would engineers, contractors, and end users choose both Hot-Dip galvanized steelcable tray
and aluminumcable tray
. The answer lies in their numerous benefits in design, installation , conveyance, execution and complete expense over the lifetime of the installation.Design and Installation Of Cable Trays :
Aluminum cable tray systems can normally be shipped from the factory during a short period of your time . Small orders can ship in only a couple of days, counting on the manufacturer’s work-load. Hot-dip galvanized cable tray systems regularly require a few days to manufacture, hot dip galvanize, and steel oneself against definite shipment.
All cable tray manufacturers must ship their cable trays to a 3rd party to possess them galvanized. This needs the cable tray to be manufactured, packed and delivered to the galvanizer. Some manufacturers return the fabric to their plants after galvanizing to examine and deburr the merchandise before packing and final shipment. Other manufacturers believe the hot-dip galvanizer to examine , deburr, and pack the fabric for shipment. The cost of a delay in getting material to the jobsite is repeatedly the value of the fabric itself and using an aluminum cable tray helps to attenuate the chance of delays.
Hot-dip galvanized steel cable tray covers pose another problem. Placing thin gauge steel covers during a hot zinc bath will often cause the covers to warp. To avoid this problem, thicker material is employed and therefore the covers are limited to 6 feet long. The extra material and therefore the extra labor required to put in shorter covers features a significant impact on the value of the whole cable tray system.
Performance Of Aluminium And Galvanized Cable Tray:
Aluminum cable tray has excellent corrosion resistance in many chemical environments and has been used for over thirty years in petro-chemical plants and paper mills .The aluminum alloy used by
cable tray manufacturers in India
- Hutaib Electricals , which is taken into account copper-free and sometimes mentioned as marine grade aluminum. Although copper-free aluminum may experience some chloride pitting during a marine environment, this corrosion is restricted and doesn't affect the structural integrity of the system.Galvanizing on steel cable trays is meant to slowly wear away because it protects the steel; anywhere where the coating is thin or has been removed can prematurely limit the product’s service life. Since aluminum cable trays are homogenous material throughout, their service life is unaffected by scratches and field modifications. When aluminum cable trays are used with chrome steel hardware, the system can perform indefinitely, with little or no degradation over time, making it ideal for several chemical and marine environments.
Total Cost
Aluminum’s many advantageous features like its corrosion resistance, superior strength-to-weight ratio,
simple field modification, fast delivery and availability, and labor saving installation all add up to a
system well worth the extra 10% to fifteen in initial price. Recently, the relative cost of aluminum to
steel has been decreasing, making the selection between aluminum and steel no contest.
