Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the plastic plates where the assembly allows polypropylene and you want broad bearing without metal head corrosion concerns, and pair them with the matching UltraFast fastener length for your insulation thickness plus deck penetration. Follow the specified fastening density and layout, checking plate seating so insulation stays flat under the membrane. Use Galvalume-coated steel plates when the system specification calls for metal.
Follow the roof system fastening specification and fall-protection requirements when installing plates on roof decks.
