Seam fastening plates are used as part of mechanically secured EPDM roofing installations to anchor membrane edges and seams. The plates distribute fixing load across a wider surface area, helping prevent pull-through and ensuring a more secure fixing point.
They are typically installed beneath seam tape or overlay material as part of a complete fixing system. Manufactured for compatibility with ClassicBond fasteners, the plates support structural stability while helping maintain membrane alignment during and after installation.
