Tech Brief
XR Rail® Family
Solar Is Not Always Sunny
Over their lifetime, solar panels experience countless
extreme weather events. Not just the worst storms in years,
but the worst storms in 40 years. High winds capable of
ripping panels from a roof, and snowfalls weighing
enough to buckle a panel frame.
XR Rails® are the structural backbone
preventing these results. They resist uplift,
protect against buckling and safely
and efficiently transfer loads into the
building structure. Their superior
spanning capability requires fewer
roof attachments, reducing the
number of roof penetrations
and the amount of
installation time.
Force-Stabilizing Curve
Sloped roofs generate both vertical and lateral
forces on mounting rails which can cause them to
bend and twist. The curved shape of XR Rails®
is specially designed to increase strength in both
directions while resisting the twisting. This unique
feature ensures greater security during extreme
weather and a longer system lifetime.

Tech Brief
XR Rail® Family
The XR Rail® Family offers the strength of a curved rail in three targeted sizes. Each size supports specific
design loads, while minimizing material costs. Depending on your location, there is an XR Rail® to match.
