COMPARISON GUIDE

Metal Building vs Wood Frame: Complete Comparison

Metal buildings cost 30-50% less than comparable wood frame construction for commercial and industrial applications, go up 50-70% faster, and require less maintenance over their lifespan. Here is a detailed, honest comparison to help you decide which construction method is right for your project.

Side-by-Side Comparison

Factor Metal Building Wood Frame
Commercial cost/SF $30-50 $80-150+
Residential cost/SF $80-150 $100-200+

Lifespan 40-60+ years 50-100+ years
Maintenance Low Moderate-High
Termite risk None Significant in GA
Fire resistance Non-combustible Combustible
Clear span Up to 200 feet 40-60 feet max
Energy efficiency Excellent (with insulation) Good (standard)
Insurance cost Lower Higher
Resale value Good (commercial) Excellent (residential)
Design flexibility Moderate High

When Metal Wins

Metal buildings are the clear choice when:

  • You need large clear-span space (60+ feet wide)
  • Budget is a primary concern and function matters more than aesthetics
  • Speed of construction is important
  • The building is commercial, industrial, or agricultural use
  • You want low long-term maintenance costs
  • The building needs to be expandable in the future
  • You are in a high-termite area (all of Georgia)

When Wood Frame Makes Sense

Wood frame construction may be the better choice when:

  • The building is a primary residence in a neighborhood with strict HOA rules
  • Complex architectural design is the priority (curves, dormers, complex rooflines)
  • The building is small (under 1,500 SF) where metal savings are minimal
  • Maximum residential resale value is the goal
  • Local codes or covenants prohibit metal-framed residential construction

Georgia-Specific Considerations

Georgia's climate and soil conditions affect this comparison in specific ways:

Termites

Georgia is in the highest termite pressure zone in the country. Subterranean termites cause billions in damage annually. Metal buildings are immune to termite damage. Wood frame buildings in Georgia require ongoing termite treatment ($150-300/year) and are still at risk of structural damage.

Humidity & Rot

Georgia's high humidity accelerates wood rot, especially in ground contact and poorly ventilated areas. Metal buildings do not rot. Proper coatings on metal buildings prevent rust, and modern Galvalume coatings last 30-40 years in Georgia's climate.

Wind Loads

Metal buildings engineered to Georgia's 115-120 mph wind speed requirements are inherently strong. Wood frame buildings rely on hurricane clips, straps, and plywood sheathing for wind resistance. Both can meet code, but metal buildings provide structural redundancy.

Foundation Costs

Foundation costs are similar for both construction types in Georgia's red clay. Both require proper footings and compacted fill. Metal buildings may have slightly simpler foundation requirements because the steel frame carries loads to specific column points.

Frequently Asked Questions

Is a metal building cheaper than wood frame?
Yes. For commercial and industrial buildings, metal construction costs 30-50% less than wood frame. A metal commercial building runs $30-50/SF while comparable wood frame runs $80-150+/SF. For residential and small buildings, the gap narrows -- a metal workshop costs $20-35/SF compared to $40-60/SF for stick-built. The larger the building, the bigger the cost advantage for metal.
How long does a metal building last compared to wood?
A properly maintained metal building lasts 40-60+ years. The steel frame itself can last indefinitely with proper coatings and maintenance. Wood frame buildings last 50-100+ years but require more ongoing maintenance (termite treatment, rot repair, painting). Metal buildings require less maintenance overall -- no termite risk, no rot, and modern coatings last 30-40 years.
Are metal buildings as energy efficient as wood frame?
Yes, when properly insulated. A metal building with closed-cell spray foam insulation (R-25 to R-40) meets or exceeds the energy performance of standard wood frame construction. Metal buildings can also incorporate cool-roof coatings that reflect solar heat. The key is proper insulation and air sealing -- a well-insulated metal building outperforms a poorly insulated wood frame building.
Can I get a mortgage on a metal building?
For commercial buildings, yes -- commercial lenders are very familiar with metal construction. For residential metal buildings (barndominiums), most lenders in Georgia now offer financing, though you may need a construction-to-permanent loan. Having PE-stamped plans and a licensed GC significantly improves your financing options.
Do metal buildings have lower insurance costs?
Generally yes. Metal buildings are non-combustible (IBC Type II construction), which often results in lower fire insurance premiums. They are also more resistant to wind damage, termites, and rot. Some insurers offer 10-20% lower premiums for metal buildings compared to wood frame. Check with your insurer for specific quotes.
