Aluminum Deep Corrugated Sheets

Aluminum Deep Corrugated Sheets are available in two nominal corrugation profiles, with bare or painted exterior surface, and in smooth or stucco embossed surface finishes. The corrugation profiles are engineered to provide strength and stiffness superior to that of standard aluminum jacketing.  Aluminum Deep Corrugated Sheets are a premier protective outer surface for mechanical insulation systems on flat surfaces, large equipment, towers, vessels, and vertical cylindrical tanks with an outer diameter larger than 8 ft.  Aluminum Deep Corrugated Sheets help protect the insulation and underlying surface from physical damage, UV exposure, corrosive environments, and water.

Recommended Uses  -  flat surfaces, equipment, towers, vessels, and vertical cylindrical tanks with an outer diameter larger than 8 ft. 

Flammability -  tested for flammability using the industry standard ASTM E84 test method. 

Surface Finishes - smooth or stucco embossed finish

3/16” Corrugated (Cross-Crimped) Finish - This finish consists of parallel grooves or crimps about 3/16” apart running in the length direction of the pipe. This finish also hides small damage and scratches to the jacketing and reduces sunlight reflection. The nature of this finish gives the aluminum jacket more ability to expand and contract to adapt to insulation movement caused by pipe or ambient temperature changes.

Also Available without Polyfilm upon request

Polyfilm Moisture Barrier (PFMB) -  engineered three layer coextruded film of polyethylene and Surlyn polymers with a total film thickness of 3 mils (76 µm) that is heat laminated in the factory to the interior surface of aluminum jacketing. JM recommends the use of PFMB on all aluminum jacketing to help prevent pitting, crevice, and galvanic corrosion of the interior surface of the metal jacketing and the insulated pipe, tank, or equipment.
