摘要:
Parallel sheet metal roofing pans having upwardly extending sides with inturned flanges along their upper edges are located at opposite sides of a batten that is in the form of an inverted sheet metal channel having spaced sides connected at their upper edges by a web and having outwardly extending supporting flanges along their lower edges projecting beneath the adjoining pans. Each of the channel sides is cut to provide it with a plurality of tongues spaced lengthwise thereof and integrally connected at one end to the side adjacent the channel web. The tongues are bent upward between the channel sides and adjoining pan sides and then hooked around the adjoining pan flanges to anchor the pans to the batten.
