Standard flat trusses are engineered to support flat or minimal-slope roof designs while maintaining consistent load distribution. They are commonly used in post-frame buildings where ceiling height and simplicity are priorities. These trusses offer straightforward installation, reliable performance and compatibility with a wide range of building types and layouts.
Why Standard Flat Trusses
Built to perform — here's what sets it apart.
Open, column-free spans
Carries roof and ceiling loads so you can skip interior bearing walls and keep floor plans open.
Clean, flush ceilings
A level bottom chord gives a flat ceiling that’s simple to insulate, wire and finish.
Fast, consistent framing
Factory-built to exact spec — every truss is identical, so framing goes up quickly and predictably.
Engineered for your loads
Galvanized steel connector plates, engineered to meet the snow and wind loads for your area.
How it's built
Our wood trusses are built from graded, kiln-dried Southern Yellow Pine lumber — top chord, bottom chord and web members — joined at each joint with engineered galvanized steel connector plates. Every truss is engineered to meet the snow and wind loads for your zip code.
Engineered to your building — long clear spans, no interior bearing walls

Recently dealt with Carson here to buy a building, my experience was great. Carson was able to setup everything online and answered every question we had (my wife and I had plenty of questions being our first building purchase) thank you for being so helpful and I hope to do more business with you guys in the future.

I am enjoying that we don't have to run to Dickson to Lowe's! Pac has provided all our needs so far without having to leave Waverly as it should be! There prices on lumber are very compatible with Lowe's, in fact they beat them on some lumber and it's a better quality! They also deliver!!

I can’t say enough good things about them.
I wanted a hobby shop on a piece of property I bought. I called PAC and the rest was easy. They had great advice and very fair pricing. I live out of state and put my complete trust in the crew. They not only met my expectations but surpassed them. I can’t say enough good things about them. Would highly recommend them.
