METAL LATTICE

摘要

Metal lattice formed of overlying slats (11 and 12) of hollow tubular form. The slats (11) are provided with apertures (18 and 19) in opposite side faces and the slats (12) with apertures (20) in one side face only so that when fastened together by a rivet (21), the rivets are hidden from one side. In an alternative connection arrangement, the slats (11) may be provided with tongues for location in slots in the slats (12). A method and apparatus for manufacturing metal lattice is also disclosed.
