Aluminum Joist ‘‘Nailers’’
Sheathing panels are supported by aluminum ‘‘nailer-type’’ joists (Figure 2.6). Each joist is a standard I beam with a wide top flange that allows a wood nailer to be inserted to provide a wider nailing surface for the sheathing panels. Other types of joists available are symmetrically designed with wide top and bottom flanges that
allow nailing strips on either side of the joist. Aluminum nailers are also shown at the top of the flying formwork system shown in Figure 4.1.
