InnoviFast™ 2-3/8 in. HD Seam Plates are used for easy installation of IKO Innovi™ TPO thermoplastic polyolefin single-ply roofs. InnoviFast 2-3/8 in. HD Seam Plates are made from 20-gauge steel that is coated with Galvalume®, a high-performance alloy of aluminum and zinc. Zinc bonds with the steel to create a barrier to moisture, and aluminum resists corrosion to provide robust protection. InnoviFast 2-3/8 in. HD Seam Plates provide excellent attachment for TPO membranes. The engineered barbed design provides increased wind-uplift performance, and the flat-bottom design is ideal for use on rigid surfaces. InnoviFast 2-3/8 in. HD Seam Plates are important components in the successful installation of an IKO InnoviTPO commercial roofing system.
