Various embodiments and features of railing systems are provided. For example, the railing system may be disposed around industrial/commercial equipment (e.g., rooftop condensing unit) that includes a baserail near the bottom of the industrial/commercial equipment and may be disposed on a structural support. The railing system may include a plurality of vertical supports extending from the baserail or structural support to above a top portion of the industrial/commercial equipment; railing extending between the vertical supports; and an attachment system to attach the vertical supports to the baserail or structural support so that the vertical supports are configured to distribute any weight received directly to the baserail or structural support via the attachment system.

A deck apparatus for assembly with a pair of opposing brace frames interconnected by a pair opposing connector bases and a deck board top frame having a plurality of deck boards disposed thereon, the connector bases having opposing posts for being received in openings in a lower end of the opposing brace frames ends and the deck board top frame having posts for being received in an upper end of the opposing brace frames, and optionally attaching a stairs riser having a plurality of spaced-apart treads or a ramp riser for extending from a deck surface at a height to a vertically lower support surface.

A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall and an overhang wall extending perpendicularly from the web wall. First and second joist support brackets include a joist support portion and a pair of attachment wings, where each one of the pair of attachment wings contacting the web wall of the perimeter support member. First and second joists each include a deck support wall and a lower wall. The deck support walls of the first and second joists are disposed between the overhang wall and the joist support portions, and the lower walls are disposed between the joist support portions and the joist support wall.
