: AluminumAluminum cable trays are fabricated fromstructural grade "copper free"(marinegrade) aluminum extrusions.Aluminum's excellent corrosion resistanceis due to its ability to form an aluminumoxide film that when scratched or cutreforms the original protective film.Aluminum has excellent resistance to"weathering" in most outdoor applications.Aluminum cable tray has excellentcorrosion resistance in many chemicalenvironments. Typically, aluminum cabletrays can perform indefinitely, with littleor on degradation over time, making itideal for many chemical and marineenvironments. The resistance to chemicals,indoor and outdoor, can best bedetermined by tests conducted by the userwith exposure to the specific conditionsfor which it is intended.

: Sheet SteelSteel cable trays are fabricated fromcontinuous roll-formed structural qualitysteel.By roll-forming steel; the mechanicalproperties are increased allowing the useof a lighter gauge steel to carry therequired load.This reduces the dead weight that mustbe carried by the supports and theinstallers.Using structural quality steel, TAV assuresthat the material will meet the minimumyield and tensile strengths of applicableASTM standards.All cable tray side rails, rungs and spliceplates are numbered for material

: Stainless SteelStainless Steel cable trays are fabricatedfrom continuous roll-formed non-magneticstainless steel.Several important conditions could makethe use of stainless steel imperative. Theseinclude long term maintenance costs,corrosion resistance, appearance andlocations where product contamination isundesirables.Stainless steel exhibits stable structuralproperties such as yield strength and highcreep strength at elevated temperatures.TAV's stainless steel cable trays are weldedusing stainless steel welding wire to ensureeach weldment exhibits the same corrosionresistant characteristic as the base metal.

traceability.The corrosion resistance of steel varieswidely with coating and alloy.

: Zinc CoatingsZinc protects steel in tow ways. First itprotects the steel as a coating and secondas a sacrificial anode to repair bare areassuch as cut edges, scratches and gouges.The corrosion protection of zinc is directlyrelated to its thickness and theenvironment. It includes the followingterms;

a. Electro galvanized ZincElectro galvanized Zinc (also known as zincor electroplated) is the process by whicha coating of zinc is deposited on the steelby electrolysis from a bath of zinc salts.When exposed to air and moisture, zincforms a tough, adherent, protective film

consisting of a mixture of zinc oxides,hydroxides, and carbonates. This film is initself a barrier coating which slowssubsequent corrosive attack on the zinc.This coating is usually recommended forindoor use and dry areas, as it providesninety-six hours protection in salt spraytesting per ASTM B117.

b. Pre-Galvanized Zinc(Mill galvanized, hot dip mill galvanized orcontinuous hot dip galvanized)Pre-galvanized steel is produced by coatingcoils of sheet steel with zinc bycontinuously rolling the material throughmolten zinc at the mills. This is also known

FeZnO

ZnZnFe

Galvanizing also protects cut and drilled edges

as mill galvanized or hot dip mill galvanized.Theses coils are then slit to size andfabricated by roll forming, shearing,punching, or forming to produce TAV pre-galvanized cable tray and ladder products.The G90 specification calls for a coating of.90 ounces of zinc per square foot of steel(0.274 kg/m²).This results in a coating of 0.45 ounces persquare foot on each side of the sheet.During fabrication, cut edges and weldedareas are not normally zinc coated;however, the zinc near the uncoated metalbecomes a sacrificial anode to protect thebare areas after a short period of time.

Molten Zinc

Hot Dip Galvanized after Fabrication cabletray and ladder products are fabricatedfrom steel and then completely immersedin a bath of molten zinc. A metallic bondoccurs resulting in a zinc coats all surfaces,including edges and welds.Another advantage of this method iscoating thickness. Cable trays hot dipgalvanized after fabrication have aminimum thickness of 1.50 ouncespersquare foot (0.4 kg/m²) each side, oratotal 3.0 ounces per square foot of steel(0.8 kg/m²), according to ASTM A123.The zinc thickness is controlled by theamount of time each part is immersed inthe molten zinc bath as well as the speedat which it is removed. The term 'doubledipping' refers to parts too large to fit into

the galvanizing kettle and, therefore, mustbe dipped one end at a time. It does notrefer to extra coating thickness.The layer of zinc which bonds to steelprovides a dual protection againstcorrosion. It protects first as anoverallbarrier coating. If this coating happens tobe scratched or gouged, zinc's secondarydefenses is called upon to protect the steelby galvanic action.Hot dip galvanized after fabrication isrecommended for prolonged outdoorexposure and will protect steel for manyyears in most outdoor environments andin many aggressive industrialenvironments.

Surface Preparation Galvanizing Inspection


All metal surfaces are affected bycorrosion. Depending on the physicalproperties of the metal and theenvironment to which it is exposed,chemical or electromechanical corrosionmay occur.

a. Atmospheric CorrosionAtmospheric corrosion occurs when whenmetal is exposed to air-borne liquid, solidsor gases. Some sources of atmosphericcorrosion are moisture, salt, dirt andsulphuric acid. This form of corrosion istypically worse outdoors, especially nearmarine environments.b. Chemical Corrosionchemical corrosion takes place when metalcomes in direct contact with a corrosivesolution. Some factors which affect theseverity of chemical corrosion include:chemical concentration level, duration ofcontact, frequency of washing, andoperating temperature.c. Storage CorrosionWet storage stain (white rust) is causedby the entrapment of moisture betweensurfaces of closely packed and poorlyventilated material for an extended period.Wet storage stain is usually superficial,having no affect on the properties of themetal.Light staining normally disappears withweathering. Medium to heavy build upshould be removed, in order to allow theformation of normal protective film.Proper handling and storage will help toassure stain-free material. If productarrives wet, it should be unpacked anddried before storage. Dry material shouldbe stored in a well ventilated 'low moisture'environment to avoid condensationformation. Outdoor storage is undesirable,and should be avoided whenever possible.d. Galvanic CorrosionGalvanic corrosion occurs when two ormore dissimilar metals are in contact inthe presence of an electrolyte (i.e.moisture). An electrolytic cell is createdand the metals form an anode or a cathodedepending on their relative position onthe Galvanic Series Table. The anodicmaterial will be the one to corrode.Whether a material is anodic depends onthe relative position of the other material.

... Thermal Contraction and Expansion

: The cable tray should be permittedlongitudinal movement in both directionsform that fixed point. When used, covers should be overlappedat expansion splices.

: Accurate gap settings at the time ofinstallation are necessary for the properoperation of the expansion splice plates.The following procedure should assist theinstaller in determining the correct gap.

1. Plot the highest expected metaltemperature on the maximumtemperature line.2. Plot the lowest expected metaltemperature on the minimum temperatureline.3. Draw a line between the maximum andminimum points.4. Plot the metal temperature at the timeof installation to determine the gap setting.

: The cable tray should be anchored at thesupport nearest to its midpoint betweenthe expansion splice plates secured byexpansion guides at all other supportlocations.

: It is important that thermal contractionand expansion be considered wheninstalling cable tray systems.The length of the straight cable tray runs

and the temperature differential governthe number of expansion splice platesrequired .

Note: every pair of expansion splice plates requires two bonding jumpers for grounding continuity.

b. Environmental Loads

b 3. Snow LoadSnow is measured by density and thickness.The density of snow varies almost as muchas its thickness. The additional design load from snowfallshould be determined using the buildingcodes witch apply for each Installation.

b 4. Concentrated loadsA concentrated static load represents astatic weight applied at a single pointbetween the side rails.Tap boxes, conduit attachments and longcable drops are just some of the manytypes of concentrated loads.

TAV Eng. Co.: Cable Way System

TAV recommends the use of heavy dutywraparound cover clamps when coveredtrays are installed in an area where strongwinds occur.

Special NoticeCovers on wind cable tray and/or cabletray installed at elevations high off theground may require additionalheavy duty clamps or thicker covermaterial.

b 2. Ice LoadsGlaze ice is the most commonly seen formof ice build-up. It is the result of rain ordrizzle freezing on impact with an exposedobject. Generally, only the top surface (orthe cover) and the windward side of acable tray system is significantly to beadded due to ice should be calculated.The maximum design load to be addeddue to ice. should be calculated as follows:

W x TiLi=( )x Di where;144

Li= Ice Load (lbs/Linear foot)W= Cable Tray Width (inches)Ti= Maximum Ice Thickness (inches)Di= Ice Density = 57 lbs/ft3

the maximum ice thickness wall varydepending on location.A thickness of 1/

2“

can be used as a conservative standard.

b 1. Wind LoadsWind loads need to be dertermined for alloutdoor cable tray installations. the mostsevere loading to be cable considered isimpact pressure normal to the cable trayside rails.

: When covers are installed on outdoorcable trays, another factor to be consideredis the aerodynamic effect which canproduce a tray. Wind moving across acovered tray creates a positive perssureinside the tray and a negetive pressureabove the cover.This presure differencecan lift the cover off the tray.

WARNING! NOT TO BE USED AS A WALKWAY,LADDER OR SUPPORT FOR PERSONNEL. TO BEUSED ONLY AS A MECHANICAL SUPPORT FORCABLE WAY.

... Additional Consideration

: Space limitationsAny obstacles which could interfere witha cable tray installation should beconsidered when selecting a cable traywidth and height. Adequate clearancesshould be allowed for installation ofsupports and for cable accessibility.

Fixed Solid BarrierComparable Material

Cable RatedOver 600 Volts

: Barrier RequirementsBarrier strips are used to separate cablesystems, such as when cable above andbelow 600 volts per NEC 392.6(F) are inthe same cable tray. The barriers shouldbe made of the same material type as thecable tray.

: Future Expansion RequirementsOne of the many features of cable tray isthe ease of adding cables to an existingsystem. Future expansion should alwaysbe considered when selecting a cable tray,and allowance should be made foradditional fill area and load capacity.A minimum of 30% expansion allowanceis recommended.

... Installition Consideration

:For Sl units: one square inch=645 square millimeters.* Total cross-sectional area of both side rails for ladder or cable trays.**Steel cable trays shall not be used as equipment grounding conductors for circuits with ground-fault protection above 600 amperes. Aluminum cable trays shall not be used as equipment grounding conductors circuits with ground-fault protection above 2000 amperes. :For larger ampere rating, an additional grounding conductor must be used.

: WeightThe weight of an aluminum cable tray isapproximately half that of a comparablesteel tray. Some factors to consider include:shipping cost, material, handling, porojectweight restrictions and the stregth ofsupport members.

: Electrical Grounding CapacityThe National Electrical Code, Article392.7 allows cable tray to be used as anequipment grounding conductor.nema 392.7

: Field ModificationsAluminum cable tray is easier to cut anddrill than steel cable tray since it is a"softer" material.Similary, galvanizedsteel cable tray is easier to cut and drillthan stainless steel cable tray.

: Installation RecommendationShorter cable tray lengths are typicallyeasier to maneuver on the job site duringinstallation. More people may be neededto manipulate longer cable tray sections,

while shorter sections might be handledby one person.Although longer cable tray lengths aremore difficult to maneuver, they canreduce installation time due to thefact that there are fewer spliceconnections. This trade-off should beevaluated for each set of job sitsrestrictions.
