Aluminum coil cladding sheet can be factory applied with moisture barrier, the function is to prevent galvanic and chemical corrosion caused by contact of dissimilar metals in the presense of moisture, and by certain insulation materials when the sheets are installed over damp insulation materials.

We have two types moisture barrier:

l Poly Surlyn

l Craft paper.

There are 8 series of aluminum alloy, from 1xxx to 8xxxx. Most common used

alloy for insulation is 1100, 1060, 3003, 3105 and 5005. 3003 is better in anti-

rust performance than 1060.

Aluminum jacketing is available in Smooth, Stucco Embossed, Corrugated

(cross-crimped) finishes, with or without moisture barrier (craft paper and poly

surlyn)

Aluminum sheet can be used as (application):

l Aluminum Jacketing is recommended for HVAC, Insulated Piping,

Tanks & vessels less than 8 feet in diameter.

l Deep corrugated sheets are recommended for diameters greater than

8 feet.

l Chemical Plants & Refineries: Distillation columns, tank farms,

fractionation units, cokers and ethylene production units.

l Paper Mills: Chemical storage tanks, breechings and ducts.

l Steel Mills: Pickle acid tanks, oxygen production units, fuel oil and tar

storage tanks.

l Miscellaneous: Power station, Food processing plants, LPG storage

units, LNG storageunits, sewage and waste water treatment plants.
