Decks With A Backbone Of Steel
Wood framing sags, twists and rots. Steel doesn't. We build decks on welded steel framing that stays flat, square and squeak free for decades, then top them with the surface you love: natural wood, low maintenance composite, or full metal decking for modern and commercial applications.
The result looks high end from every angle and structurally outclasses anything a lumber crew can nail together. It's the right answer for entertaining spaces, lakefront properties, slopes and elevated installs all over Middle Tennessee.
Deck Systems We Build
- Steel framed wood decks: the warmth of cedar or hardwood on a welded steel skeleton
- Composite decks on steel: zero maintenance surface, zero flex structure
- All metal decks: rust resistant, fire resistant and modern, ideal for commercial use
- Elevated and rooftop decks: engineered for height, load and wind
- Lakefront and slope builds: welded posts and footings for difficult terrain
- Deck railings and stairs: integrated cable, steel or iron rail systems and stair access
