(57) A shelf 10, particularly for use in supermarkets, and having high load bearing capacity,
has a shelf body member 14 and stiffening members 22,24 secured to the underside of
the body member by stud rivets 34. In manufacture, the shelf body member is precoated
on its upper load bearing surface with a wipe-clean plastics material. The stud rivets
are subsequently electrically welded to the underside of the pre-coated body member
under conditions such that no significant damage to the surface finish of the plastics
material occurs. The stud rivets are received in apertures in the stiffening members
and subsequently formed with smooth heads.
