An architectural flat pan panel featuring a 1” standing seam.

The MPI StrongSeam LF1 Panel is an architectural flat pan panel featuring a 1” standing seam that utilizes a mechanical seaming process. Primarily designed for installation over a solid deck, it can also be adapted for use over closely spaced open purlins. This versatile panel is available in both 26 and 24-gauge options and incorporates clip offsets for installation. A minimum recommended slope of 2:12 ensures proper drainage, and pan striations are a requirement for all 26-gauge panels.

Offering varying coverage widths, the StrongSeam LF1 panel comes in a standard 17” coverage for 26 gauge and options of 13”, 17”, and 21” for 24-gauge. The 26-gauge panels are available in 24 SMP colors, along with galvalume, while the 24-gauge panels boast an even wider selection of 32 PVDF stock colors, plus galvalume and gloss white. Beyond its aesthetic appeal, the LF1 panel holds a UL Class A Fire rating and a UL Class IV Impact rating, signifying its robust performance and safety.

The StrongSeam LF1 system is constructed from high-quality materials, making it suitable for both light commercial and residential applications. The elimination of end laps during installation ensures maximum weather protection and watertight integrity, even in curved applications.
