Shelving systems attached to walls are available as built-in, top-hung, free-floating, fashioned from fixed brackets or constructed as corner storage systems. The most portable shelving systems are free-standing units.
Some of the most common shelving systems are free-standing units. These are unattached and can be easily moved or shifted around. Still, free-standing shelving units can be secured to a wall with brackets for added stability.
Built-in shelving units are constructed to fit into the existing nooks and spaces of a home. In this case, the width of the unit is predetermined, but the design can be personalized by varying the height of each shelf.
Bracket shelving systems work by attaching shelves to standard rails with bracket supports. Standards are individually secured to a wall and determine the width of the unit. Shelves are added by hooking the brackets into the grooves on the standard. The system can be customized by selecting components of different shapes, sizes and colors.
Floating shelving systems give the appearance of unsupported shelves, and they lack externally visible nails and screws. Instead, internal brackets give them their needed support. Floating shelves can have low weight limits, but they offer a wide range of decoration options.
Corner shelving systems take advantage of small spaces and corners that are difficult to access. These systems offer limited storage space, and they are ideal for small items. Corner systems are free-standing or wall-hung.
