Custom layouts to match roof pitch, overhangs, and building geometry
Engineered for local snow and wind requirements

Custom Projects

For custom projects, our design and engineering teams work directly from your plans to ensure an exact structural fit:

Truss layouts tailored to your building plans
Engineered calculations for local code compliance
Design support for roof pitch, snow load, and wind conditions in Oregon and Washington
Collaboration with builders, architects, and designers

This process helps minimize field adjustments, saving time and reducing overall project costs.

Open Web Floor Trusses

Open web floor trusses are engineered for long spans, easy utility access, and strong floor support, making them ideal for modern construction.
