It’s made from powder-coated structural galvanized steel and is backed by a 25-year limited warranty. Their steel deck framing provides superior durability and longevity compared to traditional wood deck framing.

FAQ About Steel Deck Framing

  • Steel deck framing provides superior structural integrity and longevity that wood simply cannot match. It won't rot, warp, twist, or shrink over time—even through Ontario's harsh freeze-thaw cycles. You'll never worry about termite damage or deterioration, eliminating costly repairs and replacements. With dimensional stability that maintains perfect straightness for decades, your investment is protected by a comprehensive 25-year warranty. Steel framing delivers peace of mind with virtually maintenance-free performance and consistent strength that will support your outdoor living space for generations.

  • While steel framing has a higher upfront cost than traditional wood (typically 15-25% more), it delivers significant long-term value. You'll save substantially on maintenance expenses—no treatments, replacements, or repairs needed for decades. The exceptional durability means you won't face the cost of completely rebuilding your deck every 10-15 years as with wood framing. Many homeowners also benefit from potential insurance discounts due to steel's superior fire resistance and structural integrity. When considering the total lifetime cost of ownership, steel framing often emerges as the more economical choice, providing better value and peace of mind despite the initial investment.


  • Your steel-framed deck is built to last 25+ years with minimal degradation, significantly outlasting traditional wood framing which typically requires replacement after 10-15 years. Fortress steel framing is constructed from powder-coated structural galvanized steel, engineered specifically to withstand Ontario's climate conditions without warping, twisting, or rotting. This exceptional durability is backed by Fortress Building Products' comprehensive 25-year limited warranty—nearly triple the lifespan of conventional wood framing. With proper installation and basic care, many homeowners enjoy their steel-framed decks for decades beyond the warranty period, making it a truly long-term investment in your home's outdoor living space.

  • A steel-framed deck requires virtually no structural maintenance throughout its lifetime. Unlike wood framing that demands regular inspection, chemical treatments, sealing, and eventual replacement of rotted or warped components, steel framing remains structurally sound with minimal attention. Simply rinse the frame occasionally if exposed to remove any debris or dirt. There's no need for staining, sealing, pressure washing, or treating for insects. The powder-coated galvanized steel resists corrosion and maintains its integrity in all weather conditions. This dramatically reduces your ongoing maintenance costs and time investment, allowing you to simply enjoy your outdoor living space rather than constantly maintaining it.

  • Absolutely! Steel framing offers exceptional design versatility and precision engineering that actually enhances your customization options. The superior strength-to-weight ratio allows for longer spans between supports, creating more open, usable space beneath elevated decks. Steel readily accommodates complex designs including multi-level structures, curved elements, cantilevers, and unique angles that might be challenging with wood. The dimensional stability ensures your custom design maintains its exact specifications over decades without warping or shifting. Whether you envision an intimate conversation deck or an expansive outdoor entertainment area with multiple zones, steel framing provides the structural foundation to bring your unique vision to life with pinpoint accuracy and longevity.

  • Yes! Your steel deck frame is protected by Fortress Building Products' comprehensive 25-year limited residential warranty—one of the most robust coverage options in the industry. This warranty demonstrates their confidence in the structural integrity and longevity of their powder-coated galvanized steel framing system. For even greater peace of mind, Align Decking enhances this manufacturer warranty with our own industry-leading 5-year craftsmanship warranty covering all aspects of our installation work. This dual protection ensures your investment is comprehensively covered against both material and workmanship issues, providing unmatched security that wood framing simply cannot offer. Complete warranty documentation is available upon request.

  • Absolutely! Steel deck framing excels at supporting heavy features due to its superior structural strength and load-bearing capacity. Hot tubs (which can easily weigh 3,000-5,000 pounds when filled), outdoor kitchens, fire features, and pergolas are all easily accommodated with proper engineering. The precise dimensional stability of steel ensures these heavy elements remain perfectly level and secure for decades without sagging or shifting. Unlike wood framing that can weaken over time under heavy loads, steel maintains its structural integrity indefinitely. This makes it the ideal choice for homeowners planning luxury additions to their outdoor living spaces. We professionally engineer every steel deck to precisely match your specific feature requirements, ensuring rock-solid support that exceeds building code requirements for safety and performance.

  • Steel deck framing from Fortress Building Products is engineered specifically to exceed rigorous North American building codes and carries Intertek CCR0313 certification. At Align Decking, we take code compliance to an even higher standard by obtaining professionally engineered stamped drawings for every steel deck project we build. These detailed structural plans are developed by licensed Professional Engineers who certify that your specific deck design meets or exceeds all Ontario Building Code requirements. We handle the entire permit process, including submission of these engineered drawings to local building authorities for official approval before construction begins. This comprehensive approach ensures absolute code compliance, streamlines municipal inspections, and provides documented verification of structural integrity that protects your property value and ensures your family's safety.

Let’s design and build your steel-framed deck together!

As master deck builders, there are several reasons why we like steel deck framing over traditional pressure-treated lumber. For starters, its durability and longevity are unmatched. Unlike wood deck framing, steel deck framing is insusceptible to rot, decay, warping, splintering, and insect damage. Many of the modern decking products we install today are designed to last 25-50 years or more. So why put 50-year decking on a wood frame that might only last 25 years?

Another reason we love steel deck framing is for its straight uniform pieces. As Fortress Building Products say themselves, it builds flat and stays flat. This makes building decks much easier and allows for a much cleaner fit and finish thanks to the uniformity in building stock. We also think the black powder-coated framing provides a much cleaner “finished” look compared to wood, especially on raised decks where the framing is visible from underneath.

Another great feature is the ability to have greater unsupported spans, allowing for more design flexibility, and less obstructed views.
