A deck assembly uses plurality of joists preferably formed from metal located side by side and each having a web portion and a deck portion integrally formed with the web portion. The deck portion extends laterally from the web portion and the joists are spaced from one another such that the deck portions from a continuous deck surface with the joists being connected to one another.

A solid state floor lighting unit comprises a printed circuit board carrying an array of solid state lighting elements and a protective cover. The cover has openings or other light output regions aligned with the solid state lighting elements to provide light output. The protective cover has at least one edge with downwardly projecting spaced supporting tabs. These tabs form a comb structure which enables adjacent units to be interlinked. In this way a reduced pitch between lighting elements across the join between units is made possible, but the protective cover still provides the required stiffness and robustness to carry heavy loads.

There is disclosed a modular platform assembly including a plurality of legs (18), a plurality of floor beams (20a,b,c), and a plurality of connectors (24a,b,c,d) for connecting the legs (18) and the floor beams (20a,b,c). Each said connector (24a,b,c,d) comprises: a downwardly open blind recess (59) with a closed top end (60) and an open bottom end (62); and an upwardly open blind recess (64) with a closed bottom end (66) and an open top end (68). The legs (18) are mounted into the downwardly open blind recesses (59) of the connectors (24a,b,c,d) and the floor beams (20a,b,c) are mounted into the upwardly open blind recesses (64) of the connectors (24a,b,c,d) such that the legs (18) extend downwardly from the floor beams (20a,b,c).

A method according to one embodiment includes securing a first plurality of conductive sheets to a surface, applying a conductive tape to a first plurality of joints between conductive sheets of the first plurality of conductive sheets, and securing a second plurality of conductive sheets to the first plurality of conductive sheets without fully penetrating the first plurality of conductive sheets. In such an embodiment, each of a second plurality of joints between conductive sheets of the second plurality of conductive sheets is offset relative to the first plurality of joints.

Methods and associated apparatuses are described herein that provide a tile alternative material. The tile alternative material may be manufactured by providing a substrate that defines a first surface, and a second surface opposite the first surface. The second surface is configured to be secure, via an adhesive or otherwise, to a support surface. The method further includes coating an exterior layer on the first surface of the substrate, and forming a pattern element in the first surface of the substrate. Forming the pattern element includes removing material from the substrate and the coated exterior layer of the first surface to form one or more recessed portions.
