<p>Load bearing structural components, such as shelves (13) which have expanded functional capabilities are disclosed. The shelves (13) are encapsulated with sheet plastics material (14, 15) in accordance with the ARMACEL process (known per se to encapsulate structurally weak items). Preferably ribs (26), a perforated plate (36), microchips (18) or a bar code (19) are also encapsulated. The encapsulation increases the structural strength of the structural component and enables it to be rated for direct contact with food and/or pharmaceuticals. The result is a component of improved performance, serviceability and increased scope of application at a cost which is only a fraction of the cost of a new item.</p> |
