Shelving / Display
One of the commonest and simplest forms of storage is a shelf. Used in homes, offices, hotels or retail outlets, it holds items of value that are being displayed, stored, or offered for sale. It is raised off the ground and usually anchored/supported on its shorter length sides by brackets. It can also be held up between columns or pillars.
A shelf can be attached to a wall or other vertical surface, be suspended from a ceiling, be a part of a free-standing frame unit, or it can be part of a piece of furniture such as a cabinet, bookcase, entertainment center, and so on. Usually two to six shelves make up a unit, each shelf being attached perpendicularly to the vertical or diagonal supports and positioned parallel one above the other. Free-standing shelves can be accessible from either one or both longer length sides. A shelf with a hidden internal bracket is termed a floating shelf.
The length of the shelf is based on the space available and the amount of weight it is expected to hold. The vertical distance between the shelves is based on the height of the objects it can contain. Adjustable shelving systems allow the vertical distance to be altered.
