A building is only as strong as the frame that supports it. The lumber and trusses you choose determine everything from structural integrity and load capacity to how long your building will stand. That’s why we never cut corners on framing components.
Every piece of wood that goes into a Swiss Construction project is selected for its strength, durability, and performance. From the skirt boards that sit closest to the ground to the trusses that span your roof, we use reliable materials that meet or exceed modern building standards.
Whether you need a clear-span interior for a commercial pole building or a heavy-duty frame for an agricultural shop, our component systems are engineered specifically for your project.
Trusses are the engineered framework that supports your roof and creates the open, column-free space that makes post frame construction so valuable. Rather than relying on interior load-bearing walls, our truss systems transfer weight to the outer walls, giving you maximum flexibility for floor plans.
What makes our trusses different:
Available in a variety of roof pitches to match your design aesthetic and performance needs. Whether you want a steep pitch for a traditional look or a low slope for modern farmhouse style, we can engineer the right truss for your project.
Not all lumber is the same. Different species and treatment levels perform better in different parts of a building. We select each component based on where it will be used and what stresses it will face.
For non-load-bearing components like girts, purlins, and fascia boards, we use SPF lumber. It’s lightweight, straight, and easy to work with—ideal for horizontal framing that supports siding and roofing panels.
Component Material
When strength matters most, we turn to southern yellow pine and engineered LVL (Laminated Veneer Lumber) beams. These materials handle heavier loads with less deflection than standard dimensional lumber.
Any time wood is exposed to moisture or soil contact, we use pressure-treated lumber. This includes the skirt board that runs along the bottom of your walls and any posts or framing that touches concrete or earth.
Skirt boards: 2×8 treated with .60 CCA (Chromated Copper Arsenate) for maximum decay and insect resistance
Any wood exposed to the elements: Automatically upgraded to pressure-treated
Using the wrong lumber in the wrong place is a recipe for premature failure. SPF in ground contact would rot. Untreated pine in a humid livestock building would attract insects. Standard lumber in a long-span truss would sag.
We take the guesswork out of material selection. Every component is specified based on decades of real-world performance data, so your pole building stays square, level, and strong for decades[p.
Every building has unique load requirements. Let our design team engineer a truss and lumber package that matches your specific snow load, wind load, and span needs.
