Clean design & great durability! Steel frame decks are never subject to weather. Our custom-engineered post and beam structures are tailored to your project which allows for greater distances between support posts. Our steel framing is thicker and stronger than the standard 18 gauge TREX® Elevations used by other deck builders. We use helical piers or caissons for superior strength and durability to support your structure. All of our engineered plans are stamped and all welding is certified.
