Why Choose Steel Deck Framing?

Before diving into where to buy steel deck framing, let’s quickly review why it’s a preferred choice for many builders:

  1. Durability: Steel framing won’t warp, twist, or split like wood, ensuring a stable and long-lasting structure.
  2. Low Maintenance: Unlike wood, steel doesn’t require regular treatments or staining to maintain its integrity.
  3. Pest and Rot Resistance: Steel is impervious to termites, wood-boring insects, and rot, making it an ideal choice for any climate.
  4. Fire Resistance: Steel framing is non-combustible, offering an added layer of safety to your outdoor living space.
  5. Straight, Level and Consistent: Steel joists are manufactured to be perfectly straight and level and stay that way. Wood joists should be planed perfectly level before laying deck boards and can move overtime with seasonal changes.
  6. Longer Spans: Steel allows for greater spans which means fewer posts blocking your views.
  7. Designer Looks: Green pressure treated framing is not visually appealing. The black powder coated steel framing looks much nicer especially on two story decks where you see a lot more of the deck frame.
