5-V

5-V is an exposed-fastener metal roof panel from McElroy Metal with a traditional double V rib profile, also called the 5-V crimp. Listed applications are residential and light commercial roofing, agricultural and utility buildings, and coastal settings, in new construction and retrofit work on moderate-slope roofs.

It is primarily a roofing panel. It can also be used as an interior liner or an accent panel, and standard wall trim details are not offered for it.

The product data sheet draws the 5V-crimp panel profile and the panel seam, along with two fastener patterns: one at eaves, ridges and endlaps and one at intermediate spacings.

5-V is produced in 26-gauge Galvalume steel and in 29-gauge galvanized steel. The 29-gauge material is offered bare only.
