Substructural Components for Metal Buildings
Cold-formed structural members engineered for faster fabrication, reduced field labor, and flexible applications in roofing, wall systems, and retrofit structures.
McElroy Metal’s substructural components line delivers precision-engineered cold-formed steel members for framing roofs and walls, as well as retrofit applications. With factory notching, custom punching, and a broad range of gauges and depths, our components enable faster installation, lighter foundations, and fewer field modifications. Contractors, engineers, and building owners rely on McElroy for high-quality, substructural offerings that support metal building systems and retrofit projects nationwide.
What Are Substructural Components?
Substructural components are the secondary structural framing elements—purlins, girts, channels, hats, angles—that support the building envelope while connecting to primary framing. In cold-formed steel systems, these members are roll-formed to exact specifications, eliminating much of the welding, heavy fabrication, and field cutting associated with traditional steel. McElroy’s substructural offering covers the full range of profiles needed for new construction, retrofit roof recoveries, mansard framing, and solar-frame support.
Substructural Component Advantages
- Standardized roll-formed profiles enable faster fabrication while maintaining consistent quality.
- Factory notching, punching, and cut-to-length production reduce field modifications and speed up installation.
- Compared to hot-rolled steel, cold-formed components reduce overall structural weight, which can lead to lighter foundations and smaller footings.
- Consistent member geometry improves trade coordination and helps ensure accurate alignment during installation.
Substructural Components - Ideal Applications
-
New construction projects where purlins, eave struts, and framing members provide roof and wall support.
-
Wall framing systems utilizing structural components to create attachment points for metal wall panels.
-
Retrofit and recover projects where substructure forms the framework for metal-over-metal installations.
-
Commercial and industrial buildings requiring reliable structural alignment and long-term performance.
-
Residential applications where cold-formed steel components support roofing and wall cladding.
-
Solar racking and mounting systems where consistent geometry and load support are critical.
