McElroy's 2 3/4" tall symmetrical Trap-Tee system is a mechanically seamed system designed to resolve the three major shortcomings of trapezoidal standing seam roof systems: leaking endlaps, low wind uplift capacity, and repair challenges.
Site forming eliminates end laps that tend to leak over time. Oversized seams and special clips dramatically increase wind uplift capacity, and the symmetrical design allows for easy repair or alteration after the roof is installed. With a life expectancy approaching 60 years, the ability to add curbs, vents, single panel replacement, and even building additions represents a critical component.
McElroy's standard paint system for Trap-Tee is Kynar 500® (PVDF), the industry's best coating for long-term protection against panel chalk and fade. For budget-conscious or low-sloped applications, this panel is also available in acrylic-coated Galvalume®.
