No, a metal deck is generally more expensive than a wood deck, particularly concerning the structural framing.
Is a Metal Deck Cheaper Than Wood?
When comparing the initial material costs for deck framing, steel (metal) is typically more expensive than pressure-treated wood. You can expect the price of a metal deck frame to be roughly 30 to 50% higher than a comparable pressure-treated wood frame. This significant difference primarily contributes to the overall higher upfront cost of a metal deck.
Understanding Deck Material Costs
While the frame is a major component, the total cost of a deck project encompasses several elements beyond just the main structural material. These include:
- Decking Material: The surface you walk on (e.g., composite, PVC, hardwood, cedar, or pressure-treated wood).
- Railings: Options range from simple wood to more elaborate aluminum, composite, or cable railing systems.
- Labor: Installation costs vary significantly by region and contractor.
- Design Complexity: Multi-level decks, custom shapes, and built-in features will increase costs.
- Foundations: Footings and posts needed to support the structure.

Cost Comparison: Metal vs. Wood Frames
Let's break down some key differences between metal (steel) and wood frames, focusing on the factors that influence cost and long-term value:
| Feature | Metal (Steel) Deck Frame | Pressure-Treated Wood Deck Frame |
|---|---|---|
| Initial Cost | Higher (30-50% more than wood for the frame) | Lower |
| Durability | Excellent; resistant to rot, insects, fire | Good; susceptible to rot, insect damage over time |
| Lifespan | Longer (often 25+ years with proper maintenance) | Shorter (typically 15-20 years) |
| Maintenance | Very low; no warping, cracking, or splintering | Moderate; requires sealing/staining, potential repairs |
| Strength | Superior strength-to-weight ratio | Strong, but can sag or warp over time |
| Installation | Can be more specialized and labor-intensive | Generally straightforward, common skill set |
Factors Influencing Your Deck Investment
The ultimate cost of your deck will be a sum of various decisions. Consider these factors when planning your project:
- Project Specifications: A simple, ground-level deck will be far less expensive than a large, elevated deck with multiple levels and complex features.
- Local Labor Rates: Contractor fees vary widely based on geographic location and demand.
- Chosen Decking Material: While the frame is distinct, the material you choose for the deck surface (e.g., premium composite vs. standard pressure-treated lumber) will significantly impact the final price.
- Design Complexity: Custom angles, built-in benches, lighting, or pergolas will add to both material and labor costs.
- Site Accessibility: Difficult-to-access yards can increase labor time and costs.

Long-Term Value vs. Upfront Cost
While a metal deck frame has a higher initial cost, it often offers significant long-term value. Steel is impervious to rot, insects, and warping, which are common issues with wood frames. This means a steel frame can last much longer with minimal maintenance, potentially offsetting the higher upfront investment through reduced repair and replacement costs over its lifespan.
For homeowners prioritizing durability, minimal maintenance, and a longer-lasting structure, the higher initial investment in a metal deck frame might be a worthwhile consideration.
Making the Right Choice for Your Home
The decision between a metal deck and a wood deck ultimately depends on your specific priorities, budget, and desired lifespan for the structure.
- For the most budget-friendly initial build: Wood (specifically pressure-treated lumber for the frame) is the less expensive option.
- For long-term durability and minimal maintenance: A metal frame, despite its higher upfront cost, offers superior longevity and requires less upkeep over its lifetime.
Before committing, it's always advisable to get detailed quotes from reputable deck builders for both options to understand the full scope of costs for your specific project. Learn more about effective deck planning.
