Hat Channel Substructural Component

Light-gauge support for spacing, alignment, and panel attachment.

McElroy Metal’s hat channels provide lightweight, reliable support for wall and roof assemblies where consistent spacing, ventilation, or alignment is required. Their raised profile creates a stable mounting surface behind panels, making them ideal for both new construction and retrofit applications.
