Steel exterior doors are stronger and typically more affordable, while fiberglass exterior doors offer better energy efficiency, lower maintenance, and greater resistance to weather-related wear over time. Choosing between them depends on your budget, climate, maintenance expectations, and preferred appearance.
Although BGW Doors primarily sells wrought iron doors, wood doors, and fiberglass doors, we often help customers compare steel and fiberglass when researching entry door materials. Understanding the advantages and limitations of each can help homeowners make informed decisions.
Quick Comparison: Steel vs. Fiberglass Exterior Doors

Steel Exterior Doors
Steel doors provide solid construction and good security.
Pros of Steel Doors
- Strong material: Provides a solid structure.
- Security: Feels sturdy and secure.
- Affordable option: Competitively priced for basic entry doors.
Cons of Steel Doors
- Scratches can damage finish: Surface may scratch, requiring repainting.
- Heat transfer: Conducts heat, which can affect insulation in hot climates.
Fiberglass Exterior Doors
Fiberglass doors are popular for durability and low maintenance, often chosen by budget-conscious homeowners seeking long-term performance.
Pros of Fiberglass Doors
- Affordable option: Often cheaper than premium metal doors.
- Good climate performance: Handles temperature changes without major issues.
- Low maintenance: Simple cleaning with a damp towel or wood cleaner.
Cons of Fiberglass Doors
- Potential warpage: Can warp over time in harsh conditions.
- Possible discoloration: Finish may fade after long sun exposure.
Security Comparison
Proper construction, framing, and hardware matter more than material alone. Both steel and fiberglass doors can provide comparable security when installed correctly.
Climate Performance
Both materials can perform well in extreme climates if properly manufactured and installed. Sun exposure, humidity, and temperature swings can affect any door over time.
Cost Considerations
Fiberglass doors are generally more economical, while steel doors are competitively priced but may require maintenance if scratched. Budget and long-term expectations often guide the final choice.
A Note on Iron Doors
Wrought iron doors tend to offer the longest lifespan overall. Extremely durable and resistant to warping or structural movement, they are ideal for homeowners seeking maximum durability and architectural style.
