UltraPly TPO Coated Metal

UltraPly TPO Coated Metal is a flexible, non-reinforced thermoplastic polyolefin (TPO) membrane factory laminated to hot-dipped galvanized steel. It is a flashing component for the Elevate UltraPly TPO system, an accessory rather than a field membrane, and works with TPO single-ply membrane roofing.

Its technical information sheet is TIS 1504, dated September 8, 2025. The product is made in Taylor, Pennsylvania.

Two layers make up each sheet. The upper layer is the non-reinforced TPO coating. The lower layer is 24-gauge G-90 hot-dipped galvanized steel.

• TPO coating thickness: 0.032 inch (0.81 mm), tolerance plus or minus 0.003 inch.
• Sheet metal thickness: 0.023 inch (0.58 mm), tolerance 0.004 inch, minus 0.
• Coating colors: white, gray or tan (HR).

Each sheet is 4 ft wide by 10 ft long. The width is 48 inches plus or minus ½ inch (122 cm plus or minus 1 cm) and the length is 120 inches plus or minus ¾ inch (305 cm plus or minus 2 cm). A pallet holds 10 sheets and weighs 525 to 550 lb (238 to 250 kg).

Item numbers are W56TPO3023 for white, W56TPOG023 for gray and W56TPOLT023 for tan (HR).

Adjoining sections are installed with a gap of ⅛ inch to ¼ inch (3 to 6 mm). A heat-resistant tape 2 inches (50 mm) wide is placed over each joint. A 6 inch (150 mm) wide piece of UltraPly TPO Unsupported Flashing is then heat welded over the joint.

Robotic welds to the coated metal are at least 1½ inches (40 mm) wide. Hand welds are at least 2 inches (51 mm) wide.

The LEED information lists 22 percent post-consumer and 6 percent post-industrial recycled content. The material is stored in its original unopened packaging in a dry area away from physical damage and chemical contamination.
