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.

PAC Lumber is fantastic. Always helpful to me - a complete novice when it comes to building projects. Several times they have stayed open a few extra minutes for me - and always with a smile on their face. Highly recommend PAC.

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.
