PVDF (Kynar 500®)

FREQUENTLY ASKED QUESTIONS
What makes McElroy's 138T/238T panels unique?
The 138T and 238T panels feature a symmetrical design that allows individual panels to be removed and replaced without disturbing adjacent panels. This is unique in the industry—most standing seam systems require removing multiple panels to access a single one.
What's the difference between PVDF and SMP coatings?
PVDF (Kynar 500®) coatings offer superior UV resistance, longer color retention, and 40-year warranties compared to SMP coatings with 25-35 year warranties. For Texas's intense sun exposure, McElroy recommends PVDF for best long-term results.
Can McElroy panels be formed on-site?
Yes! McElroy can produce standing seam panels on-site in lengths up to 250 feet. This eliminates horizontal seams, reduces potential leak points, and allows for custom-fit installation on complex roof shapes.
What fire rating do McElroy panels have?
McElroy's MasterLok and other premium systems carry Class A fire ratings (the highest rating available), along with UL580 Class 90 uplift testing and Class 4 impact resistance ratings.
How does McElroy compare to Mueller metal roofing?
Both are excellent American manufacturers. Mueller is Texas-based with strong regional presence, while McElroy offers unique innovations like symmetrical panel designs and extended panel lengths. We're happy to help you choose the best option for your specific project.
Do McElroy panels qualify for insurance discounts?
Yes, McElroy panels that meet Class 4 impact rating standards (UL 2218) typically qualify for insurance discounts. Many Texas insurers offer 15-35% premium reductions for Class 4 metal roofs.
