XR Rail Family

Strength runs in the family.

XR Rails are the structural backbone of IronRidge pitched, flat and ground-based arrays. Their signature curve helps them to 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. Each size supports specific design loads, while minimizing material costs. Depending on your location, there is an XR Rail to match.

Force Stabilizing Curve

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.

Anodized Materials

All XR Rails are made of 6000-series aluminum alloy, then protected with an anodized finish. This prevents surface and structural corrosion, and provides a more attractive appearance. Available in clear and black finish.
BOSS Splices

Bonded Structural Splices

The BOSS™ (Bonded Structural Splice) provides a strong connection for linking multiple XR Rails. No assembly, tools, or hardware required. The built-in bonding spring bites into rail, meeting all UL standards.
