A trench drain includes a trench and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and the trench defines a trench volume therein. The peripheral side walls of the trench have a pair of opposing elongated slots formed therein and the grating has a pair of posts on opposing ends thereof. Each of the pair of posts on the grating are received in a respective one of the pair of opposing elongated slots of the trench.

A floor vent including a grille defining a plurality of vent openings and cross-members therebetween, and one or more pins corresponding to a respective one or more of said cross-members, wherein each of the one or more pins may be either (a) contained within the respective cross-members, or (b) affixed to the respective cross-members, and wherein the one or more pins are formed of material or materials that are substantially stronger than the material or materials of which the respective cross-members are formed, to provide for strengthening the respective cross-members.

An elevator trench drain includes a trench and a drain passageway. The trench has a base wall with peripheral side walls extending upwardly therefrom to define a trench volume therein. The drain passageway extends downwardly from the base wall of the trench and places the trench volume in fluid communication with a lower opening of the drain passageway. The drain passageway has a first section proximate the base wall defining a first cross-sectional area and a second section distal the base wall defining a second cross-sectional area. The second cross-sectional area is less than the first cross-sectional area and this reduction in cross-sectional area produces a head pressure that increases the flow out of the lower opening.

A roof panel includes a planar body having top and bottom edges, with a downturn edge extending therebetween, and an opposing channel edge. The downturn edge overlays a channel edge of an adjacent panel. The bottom edge overlays a top edge of another adjacent panel. A plurality of courses extends between the channel and downturn edges. Each course includes a nesting ridge to receive the downturn edge of an adjacent panel and to position a top surface of the panel flush with adjacent panels. Surface channels and contoured ridges are defined within each course. A drain aperture of the drip edge aligns with an adjacent channel edge to direct material through the drain aperture and onto adjacent panels. A gable member engages an edge when the panel has one or fewer laterally adjacent panels, wherein the gable member is flush with the adjacent planar body.

Disclosed are various embodiments of deck drainage systems. In some embodiments, the deck drainage system includes a hanger. The hanger can include a first arm and a second arm. A fastener is configured to be inserted into an opening formed in the first arm. The second arm extends from the first arm, and the second arm forms a slot for an end section of a floor panel.
