() Having a degree of stiffness, this lathing does not requirestretching, and it is used extensivelyfor wrapping steel beams or columnsfor fireproofing or finishing, for thinpartitions, and for concrete floors. An objection is sometimes madeto wire or expanded metal laths, thatthey require an excessive amount ofplaster for ordinary uses. This maybe overcome, when feasible, by theuse of the Bostwick sheet metal lath, shown in Fig. 242. This is made from sheet steel by punch-ing out loops at regular intervals. In this, and many other formsof sheet metal lathing, the surface is corrugated, besides being punched, to give stiffness and tokeep the lathing away from the sur-face to which it is applied. Sheetmetal lathing is easily adapted tothe forming
