Steel Deck Framing: Fortress & New Castle Steel Systems
Your deck is only as good as its frame. While most decks are built on pressure-treated wood, steel framing offers a rot-proof, termite-proof foundation that can outlast multiple generations of decking. We carry steel framing systems from industry leaders and can order for your project.

Why Choose Steel Deck Framing?
Traditional pressure-treated wood framing can rot, warp, and deteriorate over time - especially in Georgia's humid climate. Steel framing eliminates these problems entirely.
✓Rot Proof: Steel cannot rot, no matter how wet it gets
✓Termite Proof: Insects can't eat steel - no treatments needed
✓Dimensionally Stable: Won't warp, twist, or bow like wood
✓Stronger: Higher load capacity allows longer spans with fewer posts
✓Longer Lifespan: Steel frame can outlast 3-4 generations of decking boards
✓Fire Resistant: Steel won't contribute fuel to a fire

Steel vs Wood Framing Comparison
When Steel Framing Makes Sense:
When Wood Framing May Be Preferred:
- High-moisture locations (poolside, lakefront, low to ground)
- Areas with heavy termite pressure
- Long-span designs where fewer posts are desired
- Premium composite or PVC decking installations (match frame life to decking life)
- Commercial or multi-family projects requiring durability
When Wood Framing May Be Preferred:
- Budget-constrained projects
- Simple, small deck builds
- Contractors unfamiliar with steel installation
Installation Considerations
Steel deck framing installs differently than wood, but most experienced contractors adapt quickly:
✓Tools: Requires metal cutting blade; standard drill works for fastening
✓Fasteners: Self-tapping screws designed for steel-to-steel connections
✓Weight: Steel joists are often lighter than equivalent wood joists
✓Thermal Bridge: Consider thermal breaks when steel contacts conditioned spaces
✓Code Approval: Engineered products come with span tables for permit approval
