What’s On The Inside Counts
When comparing quotes on post frame buildings, make sure you’re looking at more than just the price. The details matter when it comes to strength, safety, and long-term value. Some bids may seem lower at first glance, but differences in materials, construction methods, and design expertise can have a big impact on durability and overall cost over time.
At QSI, we build with strength in mind, placing trusses 4 feet on center to provide greater load capacity, better wind resistance, and a longer-lasting structure.
Wider truss spacing may cut costs, but it can also lead to roof sagging, reduced stability, and costly repairs down the road. Every QSI building is also engineered in-house, ensuring your structure is designed for maximum durability and performance, not just built to a generic template.
We also build to code, even in areas without enforcement, so you can be confident your structure meets the highest safety standards. And with Builder’s Risk Insurance included on every project, your investment is protected throughout the construction process. These are just a few of the ways QSI ensures your building is built to last.
Make sure you’re getting the quality you deserve.

Why We’re Different
At QSI, we don’t just meet the minimum—we build beyond it. Our standard construction is engineered for a 115 MPH wind load, giving your building the strength to stand up to Midwest weather extremes.
