Stacking Up Steel and Wood
When approaching a new construction project, the first question that's typically asked is "Are you building with wood or steel?" Some contractors swear by lumber while other providers prefer the strength and long lifespan of metal buildings. They each have their advantages, but how do they stack up against one another?
In this blog, we aim to settle the century-old debate once and for all, and help you determine whether wood or steel framing is the best choice for your next building project.
Key Highlights TL;DR
- Wood framing keeps the upfront costs down but adds upkeep over time.
- Steel framing costs more to start, but lasts much longer with fewer repairs.
- Light-gauge steel is great for mid-size builds and small shops.
- Structural steel handles the heavy jobs, tall walls, long spans, and commercial strength.
- Steel resists fire, bugs, and weather better than wood ever could.
Types of Framing
When you get down to it, “framing” is just the bones of a building. It’s what keeps everything standing straight. But not all bones are built the same. The most common framing options are:
Wood Framing
Good old-fashioned 2x4s and 2x6s. Wood framing is what most homes and garages are built with. It’s simple, familiar, and forgiving if you make a mistake. It cuts easily and nails fast. However, it doesn’t love moisture or bugs. So, if you live where humidity’s high or termites are common, upkeep becomes part of life.
Light-Gauge Rolled Steel Framing
Rolled steel framing is the in-between option. It’s made from thin, galvanized steel sheets shaped into columns, base rails, and trusses. It’s lighter than structural steel but much stronger and straighter than wood. It’s immune to rot, settling, and even most fire risks, which makes it one of the top choices for modern construction.
Structural Steel Framing
Structural steel is the big guns. It’s often used in red iron buildings, warehouses, aircraft hangars, and large-scale agricultural projects.

Specs on Steel Framing
Steel comes in several different grades and configurations. Let’s explore how different steel framing options rank when measured against one another:
| Type of Framing | Upfront Cost (per sq. ft.) | Durability | Upkeep | Average Lifespan |
|---|---|---|---|---|
| Light-Gauge Rolled Steel | $10-$18 | High | Low | 50-75 Years |
| Structural Steel | $18-$30 | Very High | Very Low | 75-100+ Years |
Light gauge makes sense if you’re after strength without overbuilding. They’re great for residential metal buildings, metal garages, agricultural buildings, workshops, and businesses. Structural steel is more of a long-term investment and is reserved for those really big projects.
Specs for Wood Framing
Wood’s still the workhorse for most residential builds. It's easier to find, easier to fix, and most construction crews know it like the back of their hand. Let’s look at what you can expect from this classic building material:
| Framing Type | Upfront Cost (per sq. ft.) | Durability | Upkeep | Lifespan |
|---|---|---|---|---|
| Standard Lumber | $6-$12 | Moderate | Medium to High | 40-60 Years with Proper Maintenance |
If you stay on top of sealing, painting, and pest control, wood framing can last a long time. But skip maintenance for a few years, and it’ll start to show it.
Comparing Wood and Steel Against Each Other
When you put steel and wood side by side, it's clear that both materials have strengths. Just not the same kind.
| Features | Steel Framing | Wood Framing |
|---|---|---|
| Upfront Cost | Higher | Lower |
| Strength | Excellent | Moderate |
| Maintenance | Excellent | Moderate |
| Fire Resistance | Excellent | Weak |
| Pest Resistance | Excellent | Poor |
| Lifespan | 50-100 Years | 40-60 Years |
Steel’s the best choice if you’re in it for the long run. Wood’s better when you want something quick, simple, and cost-friendly right now.
How to Choose Which Framing Type is Right for You
It’s not always about what’s “better.” It’s about what’s better for you. The right call depends on your project, your timeline, and where you’re building. Below, we’ve put together a checklist of what will probably matter the most:
Environment Matters
Start with the climate. Steel wins in humid, wet, or bug-heavy areas.
Project Size
Think scale. Wood fits smaller builds and DIY jobs. Steel’s ideal for larger spans and long-term durability.
Maintenance Expectations
Consider upkeep. If you don’t want to repaint, re-seal, or patch, go steel.
Project timeline
Wood usually builds faster with standard tools and crews.
Future plans
Steel can hold resale value longer and may get better insurance rates.
Budget balance
If you can handle a slightly higher start cost, steel pays itself back over time.
Frequently Asked Questions about Wood and Steel Framing
It's never bad business to ask a few questions about the product you're buying. To help give you maximum buying power, we've answered some of the most common questions that cross our desk:
Is steel framing cheaper than wood?
Answer: No, not up front. But when you factor in maintenance, steel can cost less over time.
What are the downsides of wood framing?
Answer: Wood’s biggest enemies are moisture, bugs, and time. It can twist, rot, or attract termites if not taken care of properly.
Can wooden frames hold up to 140-mph winds?
Answer: Yes, in most circumstances if the engineering is rated for the wind speeds, they can withstand 140+ winds.
Which has lower maintenance?
Answer: Steel. You don’t have to paint it every few years or worry about rot.
Does steel framing rust?
Answer: Not modern framing. In most cases, framing is either made from galvanized steel that’s naturally resistant to corrosion or covered in a layer of iron oxide that limits the potential for rust formation.
Can I mix both materials?
Answer: Sure. Plenty of builders use steel for the structure and wood inside for finishes. You get strength and flexibility that way.
Which one’s better for insulation?
Answer: Wood insulates slightly better, but insulation materials today make it nearly a tie.
Which one lasts longer?
Answer: Steel does. Even light-gauge outlasts traditional lumber in most conditions.
