Stiffened Z-Girts, also known as lipped Z-channels, are cold-formed steel framing members used to support metal wall panels, architectural cladding, and rainscreen systems. Installed between structural supports, they create a strong sub-framing system that provides a consistent mounting surface for exterior panel systems while allowing space for insulation behind the wall assembly.

The stiffened lip along the flange increases rigidity and helps reduce deflection compared to standard Z-girts, making them ideal for supporting metal panels, ACM systems, fiber cement panels, and other faade materials.

To accommodate different shipping and jobsite needs, these Z-girts are available in 10-foot sections shipped via freight, or 7’8″ sections designed to ship via UPS for easier handling and lower shipping costs on smaller orders.
