Folks have been building with wood for a long, long time. From the old homesteads of the frontier to the barns that still dot the countryside today, timber has proven itself as strong, dependable, and forgiving—just like the folks who work with it. So when it comes time to frame the roof of your pole barn, barndominium, or workshop, and you’re thinking ahead to a finished ceiling, I’m here to tell you: wood trusses are still the best tool for the job.
Sure, there’s a lot of buzz these days about metal trusses. They’ve got their place. But when you’re aiming for comfort, code compliance, and a space you can truly finish out and enjoy—wood’s the tried-and-true answer.
Let’s take a deeper look at why that is.

A Word on Metal Trusses
Metal trusses have made their way into the pole barn world in recent decades, especially in areas where folks are aiming for long, clear spans or that industrial look. They’re sometimes quicker to install and can reduce material use in simple, open-span buildings.
But here’s where the story takes a turn: most metal trusses in our industry are built strictly for the roof load—rain, snow, and wind—not for the ceiling underneath. That bottom chord of the truss—the part you’d hang your ceiling from—is often rated for just 1 to 2 pounds per square foot. That might be fine for some light wiring or a couple of shop lights, but it’s nowhere near enough for drywall, insulation, or ceiling panels.
A Handy Tip:
When a truss isn’t rated for ceiling load, adding drywall later can lead to sagging, cracking, or worse.
What the Codes Require
Building codes are clear: if you plan on installing drywall overhead, your trusses must be engineered to carry a ceiling load of 10 pounds per square foot (psf). That accounts for the weight of drywall, insulation, fixtures, and about anything else you’d normally attach up there.
Metal trusses spaced 8 to 12 feet apart just won’t cut it. Drywall, even the good stuff, isn’t meant to span more than 2 feet without support. That means if you’ve got wide-spaced metal trusses, you’ll have to frame in a whole new ceiling structure underneath—a lot of work, a lot of lumber, and a lot of money that could’ve been saved by planning better from the start.
Retrofitting? It’s No Picnic.
Think you might just upgrade your trusses later? Let me save you a heap of trouble: reinforcing existing metal trusses to carry ceiling loads is no small job. It usually requires an engineer’s stamp, custom solutions, and enough cash and effort to make you wish you’d just gone wood from the get-go.
Why Wood Trusses Still Win
Wood trusses aren’t just old-fashioned—they’re wise. Here’s why they’re the right pick for finished ceilings:
Built With Ceilings in Mind
Wood trusses from DIY Pole Barns can be engineered right from the start for a 10 psf bottom chord dead load. That means they’re ceiling-ready out of the box. Just let us know you’re planning for one, and we’ll take care of the engineering.
Flexible Spacing
Wood trusses are far more flexible in how they’re spaced. You can go 2-foot, 4-foot, 8-foot, or even 12-foot centers depending on the design. But for finished ceilings, 2-foot spacing is the gold standard. That lines up with drywall sheets and keeps your ceiling strong, straight, and easy to install.
Easy to Modify
If your trusses are spaced wider than 2 feet, no worries. You can always add ceiling joists or nail up furring strips to create 2-foot support spacing. It’s straightforward work—nothing a DIYer with a hammer and a level can’t handle.
Insulation and Utilities? Simple.
Running wiring, installing lights, and packing in insulation is just plain easier with wood. You’ve got room to work, and you can staple, screw, or drill where needed without fighting metal edges or special brackets.
Think Ahead—It’ll Save You Later
One of the smartest things you can do is plan for a finished ceiling during the design phase. By default, many pole barn trusses—wood or metal—are only rated for 1 to 5 psf. At DIY Pole Barns, our standard truss design includes a 5 psf bottom chord dead load, which is suitable for basic lighting, steel ceiling liner, and insulation, but certainly not drywall.
Once the building’s up, retrofitting gets complicated and expensive—and in some cases, downright impossible. So don’t wait. Let us know your ceiling plans when you order. Contact our team early to ensure your trusses are designed right from the start—no guesswork, no regrets. We’ll make sure you’re set up for success.
What Can Go Wrong?
It’s not just a matter of convenience—getting the ceiling load wrong can lead to real issues:
- Structural problems like sagging and bowing.
- Failed inspections if your trusses aren’t rated properly.
- Costly upgrades later on, if reinforcement is even possible.
A Handy Tip:
Drywall should never span more than 24 inches. Thicker panels (5/8″) can go that far, but anything more and you’re asking for trouble.
Let’s Talk Spacing
When it comes to truss spacing, here’s what makes sense:
- Agricultural or storage buildings: 4 or 8 feet on center is common.
- Living spaces and barndominiums: 2-foot spacing is best.
If your spacing’s wider, wood trusses make it easy to add support. Just nail in some joists or strips and you’re back on track—no welding, no headaches.
The Long Story Short
Wood trusses are still the reigning champion for any pole barn or barndominium with a finished ceiling. They’re strong, simple, and adaptable—everything you want when you’re building something meant to last.
At DIY Pole Barns, we’ll make sure your trusses are designed to match your plans. Just give us a heads-up about your ceiling needs, and we’ll engineer everything to code—no surprises, no hidden costs.
