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

PAC lumber is the place to go for just about anything you need. Had them build my garage and it turned out awesome! Easy to design right in the store. Very professional crew hardly any waste left at the end of the job. Anytime I called I was treated great and all my questions were answered. Thanks to Christopher and all the PAC lumber employees for all the help.

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.

We have a huge build going on for a year and we set up an account for our builder to use at PAC. PAC has been very fair with their prices and competitive with with the large box stores. It is nice that for every purchase we get a statement emailed to us. We appreciate all that you have provided to make our build a success. We will continue to call upon you in the future for all our building needs.
