TPA Coated Metal

For Fabricating Perimeter and Penetration Flashings Compatible with TPA Membrane

TPA Coated Metal is used to fabricate perimeter edge metal and flanged metal flashings for use with TPA Roof Systems. The factory-laminated TPA coating on the metal allows for a heat-welded bond to be field fabricated between the TPA Coated Metal and TPA Single Ply Membrane.  TPA Coated Metal is available in white.


TPA Coated Metal is manufactured from a flexible non-reinforced Tremco TPA (Tri-Polymer Alloy) membrane factory laminated to hot-dipped galvanized steel. The metal consists of 24 gauge (0.023” minimum) G90 hot dipped galvanized steel with a back wash coat of 0.0001” clear acrylic, laminated on one side with a 20 mil unreinforced TPA Membrane.
