Boltless shelving is a type of shelving, usually in standalone units, that is assembled without nut and bolt fasteners.
The idea behind the design of Boltless Shelving systems is to provide an easily adjustable and quick-to-assemble shelving unit. Many types of boltless modular shelving are available, utilizing a number of different designs both for assembly and for basic structure, some of which rely on the hardware and assembly methods to provide strength to the overall structure as well as to simply hold the pieces together.
One of the most common types of Boltless Shelving is wire rack shelving.
This type of shelving is built using shelves constructed of heavy gauge welded wire. At each corner of the shelf, a vertical cylinder of metal is welded to the shelf structure. The legs of the unit fit through these cylinders. Wire rack shelving is found in many restaurants, shops, garages, and warehouses. It is good for light to medium duty, but is not suitable for supporting very heavy loads.
Numerous other types of Boltless Shelving employ other methods of assembly and use other shelving materials. Some use vertical supports with slots in them that accept metal clips that support particle board, plywood, metal, or full-grain wooden shelves. The shelves provide stability to the unit, preventing swaying and twisting.
Some types of boltless shelving are pre-assembled units, constructed from welded or riveted parts. Wall mounted shelving employs metal tracks that use cantilevered shelf supports to hold shelves. Other types of boltless shelving are possible, depending on human ingenuity, such as simple garden or greenhouse shelving, constructed from stacks of concrete blocks with planks laid on them for shelves.
