What Is an Aluminum Hat Channel?

An aluminum hat channel is a structural support channel with a cross-sectional shape resembling a "hat" . It typically features:

• A flat top (mounting surface)

• Two vertical legs

• Two outward flanges at the base for fastening

Common Uses

1. Wall Furring Systems

• Used to create a level surface for drywall or panels on masonry, concrete, or metal stud walls.

• Provides spacing for insulation, wiring, or plumbing.

2. Ceiling Suspension

• Installed horizontally under roof trusses or structural ceilings.

• Supports ceiling panels such as drywall, acoustic tiles, or metal ceilings.

3. Exterior Cladding Support

• Forms a rainscreen attachment system that supports metal panels, composite cladding, or other façade elements.

4. Fire-Resistant Assemblies

• In non-combustible construction, aluminum channels are sometimes used to meet fire code requirements (check local regulations, as aluminum melts under high heat).
