LF15 Panel

  • Architectural flat pan panel with 1.5” mechanical standing seams

The MPI StrongSeam LF15 Panel is an architectural flat pan panel distinguished by its 1½” standing seam, which is mechanically seamed to ensure a secure and weather-tight connection. While typically installed over a solid deck, these panels can also be utilized over closely spaced open purlins, offering versatility in application. Available in both 26 and 24-gauge options, the LF15 panel requires pan striations for all 26-gauge selections and is suitable for roofs with a minimum recommended slope of 1:12.

Offering standard coverage widths of 16” for 26 gauge and options of 16”, 18”, and 20” for 24 gauge, the StrongSeam LF15 panel provides flexibility in design and material usage. The 26-gauge panels are offered in 24 SMP stock colors, along with galvalume, while the 24-gauge panels come in an expanded range of 32 PVDF stock colors, including galvalume and glossy white. Beyond its aesthetic qualities, the LF15 panel boasts a UL Class A Fire rating and a UL Class IV Impact rating, highlighting its robust construction and resilience.

Combining the visual appeal of an architectural panel with semi-structural performance, the StrongSeam LF15 system is designed for longevity and adaptability. Its 1.5” leg height necessitates mechanical field seaming, which can be done at either 90° or 180° based on the project’s specific uplift requirements. The StrongSeam LF15’s concealed-fastener clip system allows for maximum design flexibility.
