The difference between the PLN3™ profile and HSN3 profile is the method of sidelap attachment; the panels themselves are identical in both geometry and material properties.  The prefix “PL” designates a PunchLok® II version of the N profile, while HSN indicates a top seam weld or button punch version of the same profile.

Type N profiles are 3-inch deep structural roof deck that provide both vertical load and diaphragm shear capacity.  The profile contains 4 ribs and is 32 inches wide with male and female edges, creating an interlocking side lap when installed.  The 3-inch deep ribs make N deck ideal for longer span conditions where B deck falls short.  N deck is typically used for span conditions greater than 10 feet or when a specific aesthetic look is desired.  The narrow low flutes and wide high flutes of N Deck create a very uniform look from the bottom side.
