The Trap-Tee symmetrical metal roofing system from McElroy Metal is a site-formed, mechanically seamed system, measuring 2 3/4-inches tall. Trap-Tee is designed to resolve the three major shortcomings of trapezoidal standing-seam roof systems: leaking end laps, low wind-uplift capability and repair difficulties. Site-forming eliminates end laps vulnerable to leaking over time. The oversized seam and special clips dramatically increase wind-uplift capacity, and the symmetrical design allows for easy repair or alteration after the roof is installed. Standard clips are 16 gauge and 8-inches long while Super Clips are 16 gauge and 16-inches long. Offered with Sherwin-Williams PVDF Fluropon coating, the Trap-Tee has a life expectancy approaching 60 years. Rectangular metal buildings and tilt-up warehousing are the best candidates for the Trap-Tee panel in remove and replace, as well as re-cover projects.
