Metal vs. Wood Trusses: Pros, Cons, and the Best Choice for Your Pole Barn
Summary:
This blog post compares metal and wood trusses for pole barns, highlighting that both have unique advantages. Metal trusses are "near-invincible," resisting rot, insects, and fire, and are superior for large spans despite their higher initial cost. Wood trusses are more affordable and suitable for smaller, budget-friendly projects, but they require more maintenance to protect against pests, rot, and fire. The best choice depends on the project's specific needs, including size, budget, and desired durability.
Choosing the right trusses for your pole barn might not seem like the most thrilling task—until something goes wrong.
Imagine dealing with a sagging roof after a heavy snowfall or discovering termites have turned your investment into their lunch.
Not exactly the scenario you'd envisioned, right?
At Buffalo River Truss, we completely understand the headache (and the heartache) involved when your building doesn't perform as expected. That’s why we've crafted this guide to help you make an informed choice between metal and wood trusses. By the end of this post, you'll feel confident and clear about which truss type is the best fit for your project.
Let’s get started!

Metal vs. Wood Trusses: An Overview
Pole barns are impressively versatile. Whether you’re building an agricultural storage facility, a commercial warehouse, or a cozy residential garage, the right trusses can significantly influence the durability, functionality, and longevity of your structure.
Metal trusses, primarily steel, are known for their brute strength and low maintenance, while wood trusses bring affordability and flexibility to the table. Both options have unique advantages, but each shines under different circumstances.
We’ll take a look at both options in multiple categories so you can choose which type of truss is best for your project.
Metal or Wood Trusses: Which is More Durable?
When deciding between metal and wood, it’s critical to understand their unique strengths and weaknesses clearly.
Durability: Steel Strength vs. Wood Vulnerability
Ever heard the phrase "tough as steel"?
It’s not just catchy—it’s true.
Metal trusses offer near-invincible durability. Steel stands firm against moisture, rot, insects, and even fire. If you're building in harsh conditions or regions prone to extreme weather, metal might be your hero.
Conversely, wood trusses require diligent care. Without protective treatments, they can become vulnerable to rot, pests, and fire damage. But don't write wood off just yet; with proper maintenance and treatments, wood can be a resilient and reliable choice.
Which is More Expensive – Metal or Wood Trusses?
Most times in life, you get what you pay for.
Let's look at trucks, for example. The F-150 outshines the Ford Ranger in all categories: power, durability, and aesthetics. Of course, you’ll also pay more for the F-150.
Getting an amazing product for cheap is something that consumers need to put to bed. If you want top-of-the line products, you’ll usually need to pay more.
The same is true for trusses.
Metal trusses are more expensive than wood trusses. But that’s not the whole story.
Yes, metal trusses can mean digging deeper into your pockets initially, but the trade-off is fewer maintenance costs and replacements over time. Think of it as investing in peace of mind.
That said, if budget is your primary concern (especially in the short-term) wood trusses are likely a better fit for you.
Maintenance: Hands-Free Metal vs. Hands-On Wood
If your ideal weekend doesn't involve inspecting and treating wooden trusses, steel might be your best bet. Metal requires minimal care and can virtually take care of itself. It's ideal if you'd rather spend your free time relaxing, fishing, or, frankly, doing anything other than maintenance.
Wood trusses aren’t maintenance-free, but with regular attention and care, they can last for decades.
Many building experts recommend visually inspecting wooden trusses at least once or twice a year, especially if you live in an area prone to high humidity or extreme temperature shifts. During each inspection, look for subtle changes to the wood—such as new cracks or dark spots—as they may indicate internal moisture buildup.
Span Capabilities: Go Big or Go Home
When it comes to spanning larger distances without internal supports, metal trusses clearly take the crown. They allow vast open spaces perfect for warehouses, hangars, and expansive agricultural facilities.
Wood trusses work wonderfully for smaller or residential buildings but usually require additional internal support beams for broader spans, slightly limiting open interior spaces.
Environmental Considerations and Long-term Value
The environmental impact also weighs into this decision. Steel trusses, while energy-intensive during production, are highly recyclable and have an impressively long lifespan. They often outlast buildings themselves.
Wood trusses are renewable and naturally sequester carbon dioxide, beneficial when sourced sustainably. However, their shorter lifespan and maintenance needs could lead to increased environmental impacts over time if replacements become necessary.
Long-term value also favors metal due to lower maintenance and replacement costs, though wood’s initial savings can appeal strongly to budget-conscious builders.
Ideal Use Cases for Metal Trusses
So, at the end of the day, which should you choose – metal or wood trusses?
The answer: it depends.
But, here’s a helpful cheat sheet for both types of truss to know if they are right for you.
Metal trusses are a no-brainer for specific scenarios:
- Massive Spans: Aircraft hangars, expansive agricultural buildings, commercial warehouses.
- Tough Environments: Coastal areas, heavy snow regions, or storm-prone locations.
- Fire-Resistant Structures: Buildings where fire codes are stringent.
In short, if your building demands durability, safety, and large clear-span capability, metal trusses are your go-to.
Ideal Use Cases for Wood Trusses
Wood trusses thrive when cost and customization matter most:
- Residential & Small-scale Structures: Barns, garages, and smaller storage buildings.
- Budget-Friendly Builds: Projects with limited initial capital.
- Highly Customized Designs: Unique or intricate architectural styles.
If your project calls for flexibility, affordability, and easy customization, wood trusses offer unmatched benefits.
Choosing the Right Trusses for Your Project
Still feeling stuck? Here’s a quick guide to help pinpoint your needs:
- What’s the primary purpose of your barn? (Agricultural, commercial, residential)
- What is your initial construction and long-term maintenance budget?
- Do you need extensive, open internal spaces or are internal supports acceptable?
- What environmental conditions (snow, rain, wind, heat) will your structure face?
- Is fire resistance a significant concern?
- How much time and effort can you devote to ongoing maintenance?
Wrapping Up: Making the Right Choice
Metal or wood, both truss types have their rightful place in construction. If robust strength and minimal fuss appeal to you, metal trusses will make your life easier. For those prioritizing affordability, flexibility, and customization, wood trusses might just be your perfect match.
