One of the most common questions our Project Sales Consultants are asked during the pole barn building process is whether or not the concrete pad should be poured before or after the post frame building is constructed. The short answer to this question is it depends.

Rafters vs. trusses. Two different words that can easily be confused with one another (especially if you’re a construction newbie). Although both types of components are used to support the roof of a building, they each have their place in post frame construction.

Every post-frame builder wants you to purchase their product over the competition. It’s the nature of business. Their pole barns are superior in terms of structural integrity. They use higher-quality building materials that withstand the test of time. Their warranty covers more components for longer periods. Their construction crews are more efficient. You get the gist. As consumers, we hear these claims all the time. But, how do you know if their post-frame buildings are the best on the market? Do they have concrete evidence to back up such a bold statement?

The truss is just one component in the overall building system. Believe it or not, you can have the most robust truss system, and your building may still fail. You’re probably wondering how that could happen, and we’ll explain why that is possible later on. But remember, it’s important that the load path is followed to the foundation of the building as it resists multiple loads, often co-occurring. Trusses must handle all the loads applied to the roof steel and purlins and transfer those loads effectively to the columns, hence the importance of the truss to column connection.

Pole barn kits (also known as material packages) are increasing in popularity among DIYers. If you’ve stumbled across this blog, there’s a good chance that you’re interested in taking on your own building project. Maybe you have construction knowledge, and if not, we’re sure there are YouTube videos that you can watch for guidance.

Over the years, the span size of trusses has evolved. In the 1980s, post frame builders commonly used 60’ (one-ply) trusses, and larger trusses (72’ and 80’) were made of two-ply lumber. The more ply (or layered material), the stronger the truss. At the time, post frame builders were unable to hang or lift trusses without any bending or bowing. The higher up in the air, the more stress placed on the lumber. Consequently, it was easier to produce and swing one-ply trusses.
