Flex Fit
Bridging Architectural Vision and Structural Performance
In residential construction, design and structure often speak two different languages. Architects create form, rhythm, and spatial experience — while structural engineers focus on strength, efficiency, and compliance.
With conventional systems, especially in the shift from wood framing to steel, these two worlds often clash. Architects must compromise dimensions, rework facade elements, or adjust wall thicknesses to fit a new structural system.
At LEFF, we believe that shouldn’t be necessary. That’s why we developed Flex Fit — a hybrid cold-formed steel framing solution engineered to integrate into typical wood-based architectural layouts with minimal or no design changes required.

Key Features of Flex Fit:
- Dimension Compatibility: Wall assemblies match the footprint of standard 2×6 or 2×8 wood framing, preserving interior and exterior proportions.
- Opening Alignment: Windows, doors, and facade elements remain in their designed positions, without structural conflicts.
- Facade Integrity: No need to adjust cladding systems or rainscreens; Flex Fit accommodates architectural finishes as originally specified.
- Reduced Re-Engineering: Saves time and cost in design development, permitting, and shop drawing phases.
For architects: Flex Fit means freedom to design with steel, without sacrificing your creative intent.
For builders: Faster approvals, simpler coordination, fewer unexpected issues on site.
For homeowners: The aesthetic and spatial quality envisioned by the architect, backed by LEFF’s non-combustible steel performance.
Flex Fit isn’t just a framing system — it’s an architectural enabler.
