MaxRun-238™

The MaxRun-238 is a premium mechanical seam metal roofing panel from Taylor Metal, engineered for exceptional performance and versatility. Ideal for low-pitch roofs (suitable for a wide range of applications, Please Inquire for high-pitch roofs), this innovative panel supports nearly limitless panel lengths thanks to its advanced clip system that accommodates infinite thermal movement—eliminating concerns over expansion, contraction, or end laps on long runs.
